Description

  The present invention relates to a horizontal container filled with a granular catalyst or a granular adsorbent, and more particularly relates to a horizontal container filled with a granular catalyst such as a reforming catalyst or a desulfurization catalyst or a granular adsorbent such as a granular desulfurization agent. .

  A horizontal type reformer or desulfurizer in which a granular catalyst is filled in a container is known. However, when such a horizontal reformer or horizontal desulfurizer is used for a long time, the granular catalyst particles are crushed and become finer and clog downward. For this reason, as shown in FIG. 11 (a), gas initially flows in the catalyst, but as time passes, a space is created in the upper part, and as shown in FIG. 11 (b), the gas is shortcut to that space. Therefore, the reforming effect and the desulfurization effect are remarkably lowered with time. FIG.11 (c) is a perspective view of Fig.11 (a).

  In order to avoid such a problem, a reformer having a shape as shown in FIG. 12 has been considered (Japanese Patent Laid-Open No. 2006-273635, hereinafter referred to as “635”). However, in this case, partition walls (413, 414) for forming a gas flow path must be arranged in the high-temperature reformer, and there is a problem that if the partition wall thickness is made thin, the partition wall is distorted by heat. When the thickness is made thick, there is a problem that the reformer becomes large. In addition, since the gas flow path meanders in the reformer, the contact area between the outer surface of the reformer and the gas is reduced, and heat from the outside is not easily transmitted to the center of the reformer, so that sufficient reforming performance is achieved. It may not be obtained.

  Hereinafter, aspects of the present inventions (1) to (4) will be sequentially described.

<Aspect of the present invention (1)>
The present invention (1) is a horizontal container filled with a granular catalyst or a granular adsorbent. The container has a basic portion and a raised portion above the basic portion, and the space is filled with a granular catalyst or a granular adsorbent.

  Here, as shown in FIG. 11 (c), the basic portion of the container has a quadrangular or rectangular cross section, which extends to the left and right, and has a shape in which both left and right ends are closed with wall members. Part. In the present invention (1), since the cross section has a quadrangular cross section or a rectangular shape and has a basic portion extending left and right, and a swelled portion above the basic portion, the space combining them is filled with the granular catalyst or the granular adsorbent, Of the four surfaces having a quadrangular cross section or a rectangular shape, a raised portion is formed instead of the upper surface. The cross section is not limited to a quadrangular shape or a rectangular shape, but may be a circular shape or an elliptical shape.

  A gas inlet pipe to be processed and a gas outlet pipe for processed gas are respectively arranged on the wall members at the left and right ends of the basic portion in the horizontal direction. The gas to be treated is introduced from one of the gas to be treated gas introduction pipes in the horizontal direction, flows through the granular catalyst in the container, and is led out from the treated gas outlet pipe on the opposite side.

  FIGS. 1-2 is a figure explaining the aspect of this invention (1). 1 (a) and 1 (b) are perspective views, FIG. 1 (a) shows a state in which the raised portion swells in parallel from the left and right sides toward the center, and FIG. 1 (b) shows the raised portion on the left and right. It is the aspect which swelled in the taper shape toward the center part from both sides. FIG. 2 is a cross-sectional view taken along line AA in FIGS. 1A and 1B, and FIG. 2A is a cross-sectional view taken along line AA in both FIG. 1A and FIG. become that way. That is, in terms of the cross section of the basic portion and the raised portion, as shown in FIG. 2 (a), the basic portion has a rectangular shape with a long cross section on the left and right, and the raised portion has a triangular shape.

  As such, in a horizontal type container in which the granular space is filled in the original space in the container [see FIG. 11 (c)], that is, the space of the basic part and the raised part according to the present invention, the gas to be treated is used in the container. After the start, as shown by the middle wave arrow in FIG. 2 (a), it flows through the granular catalyst filled in the original space of the container. The gas to be treated is introduced from one side in the lateral direction and flows through the granular catalyst in the container, and the gas having been treated gas is led out from the other side.

  When there is no raised portion as in the prior art, that is, when the shape does not rise upward, the gas initially flows through the catalyst as shown in FIG. As shown in FIG. 11 (b), the gas is short-cut into the space, and the catalytic effect and adsorption effect in the container are remarkably lowered with time.

  On the other hand, as shown in FIGS. 1 and 2, the horizontal type container filled with the granular catalyst or the granular adsorbent is formed by forming the horizontal type container filled with the granular catalyst or the granular adsorbent upward. Even if the catalyst particles or the adsorbent particles become finer after a long time since the start of use, as shown in FIG. 2 (b), a space without the particulate catalyst or the particulate adsorbent is formed at the top. It is only a part, Thereby, the length which a gas shortcuts can be shortened.

An adsorbent reservoir is provided. And the granular catalyst or granular adsorbent is filled in the space of the basic part, the raised part and the storage part.

  Of these, the swelled portion, that is, the portion swelled in a tapered shape from both the left and right sides toward the center, is a triangular shape as in the case of the present invention (1). The storage part has a cylindrical shape, a prismatic shape, or any other appropriate shape, and its internal space is connected to the space of the raised part. The height and volume of the storage unit can be set as appropriate.

  As such, in the container, the original space [see FIG. 11 (c)], that is, a horizontal type container in which a granular catalyst storage part is provided at the basic part, the raised part and the top part and is filled with the granular catalyst or the granular adsorbent. In FIG. 3, the gas to be processed flows through the granular catalyst filled in the original space of the container as indicated by the waved arrow in FIG. 3A after the start of use, and the processed gas is derived from the opposite side. .

  When the shape is not raised upward as in the prior art, the gas initially flows in the granular catalyst as shown in FIG. 11 (a). As shown, the gas has a shortcut to the space and the gas does not pass through the granular catalyst, so that the catalytic effect and the adsorption effect in the container are remarkably lowered with the passage of time.

  On the other hand, a horizontal container filled with a granular catalyst or a granular adsorbent is added to the basic part as shown in FIG. 3 and has a raised shape above it, and a storage part for the granular catalyst at the top. Even if the catalyst particles or the adsorbent particles in the container become fine due to a long period of time after the start of use of the horizontal type container filled with the granular catalyst or the granular adsorbent, it is shown in FIG. As described above, the granular catalyst or the adsorbent in the storage part descends and flows into the rising part, so that the gas can be prevented from being short-circuited and the length thereof can be shortened.

  Further, even if the catalyst particles or the adsorbent particles become finer after a long time since the start of the use, as shown in FIG. 2 (b), there is a space without the catalyst particles or the adsorbent particles. Only the apex having a triangular cross section is formed, whereby the length of the gas shortcut can be reduced.

And the granular catalyst or the granular adsorbent is also filled in the spaces of the plurality of raised portions. Although FIG. 4 shows a case where there are two raised portions, a plurality of three or four are provided according to the scale of the container. In terms of the cross section of the raised portion, it is triangular as shown in FIG.

  In such a container, in the horizontal type container in which the original space [see FIG. 11 (c)], that is, the basic portion and the plurality of raised portions according to the present invention are filled with the granular catalyst or the granular adsorbent, After the start of use of the horizontal container filled with the granular catalyst or the granular adsorbent, the gas passes through the granular catalyst or the granular adsorbent filled in the original space of the container as indicated by the arrow in FIG. 4 (a). Flowing. The gas to be treated is introduced from one side in the lateral direction and flows through the granular catalyst or the granular adsorbent in the container, and the treated gas is led out from the opposite side.

  When there are not a plurality of raised portions on the upper side as in the prior art, as shown in FIG. 11 (a), the gas initially flows in the catalyst or the adsorbent. As shown in FIG. 11 (b), the gas shortcuts to the space, and the catalytic effect and the adsorption effect are remarkably lowered with the passage of time.

  On the other hand, as shown in FIG. 4 (a), an original space [see FIG. 11 (c)], that is, a basic part and a plurality of the upper part thereof are placed in a horizontal container filled with a granular catalyst or a granular adsorbent. As shown in FIG. 4 (b), there is no catalyst particle or adsorbent particle even if the catalyst particle or adsorbent particle becomes fine after a long time by filling the rising part of the particle catalyst or granular adsorbent. The space is formed only at the top, and this shortens the length of the gas shortcut.

<Aspect of the present invention (4)>
The present invention (4) is a horizontal container filled with a granular catalyst or a granular adsorbent. The container has a basic part and a plurality of raised parts above the basic part, and has a storage part for a granular catalyst or a granular adsorbent at the top of the raised part, and the granular catalyst or the granular adsorbent in these spaces. It is characterized by filling. The gas to be treated is introduced from one side in the lateral direction, flows through the granular catalyst or granular adsorbent in the container, and is led out from the opposite side.

  FIG. 5 is a diagram for explaining an aspect of the present invention (4). As shown in FIG. 5 (a), a horizontal container filled with a granular catalyst or a granular adsorbent is provided with a plurality of raised portions that are tapered from the left and right sides toward the center, and A storage part for a granular catalyst or a granular adsorbent is provided at the top. And the granular catalyst or granular adsorbent is filled in the space of the basic part, the raised part and the storage part.

  As such, the original space of the horizontal container filled with the particulate catalyst or the particulate adsorbent (see FIG. 11C), that is, the basic portion, the plurality of raised portions, and the storage portion at the top of each of the raised portions. In the horizontal type container filled with the particulate catalyst or the particulate adsorbent, the gas to be treated is filled in the original space, that is, the basic portion of the container as shown by the middle wave arrow in FIG. Flows through granular catalyst or granular adsorbent.

  When the shape does not rise upward as in the prior art, as shown in FIG. 11 (a), the gas initially flows in the granular catalyst or the granular adsorbent, but as time passes, a space is formed in the upper portion. As shown in (b), the gas is short-cut into the space, and the catalytic effect and the adsorption effect are remarkably lowered with the passage of time.

  On the other hand, as shown in FIG. 5 (a), a horizontal container filled with a granular catalyst or a granular adsorbent is provided with a plurality of raised portions, and each of the raised portions is granular at each top. Even if the catalyst particles or the adsorbent particles become fine after a long time by providing the storage unit for the catalyst or the granular adsorbent, as shown in FIG. 5B, the granular catalyst or the granular adsorbent in the storage unit As the gas descends and flows into the swell, it is possible to prevent the gas from being short-cut and to reduce its length.

  Even if the catalyst particles or the adsorbent particles become finer after a long time, as shown in FIG. 2 (b), a space without the catalyst particles or the adsorbent particles is formed only at the top. Yes, this can reduce the length of the gas shortcut.

<Experiment 1: Experiment on Inclination Angle at Swell>
In the horizontal type container filled with the granular catalyst or the granular adsorbent of the present invention, the original space and the raised portion of the horizontal type container filled with the granular catalyst or the granular adsorbent are filled with the granular catalyst. This experiment 1 is an experiment for obtaining an indication of how much the bulge angle of the bulge portion should be increased.

  When the granular catalyst (the reforming catalyst with Ni supported on the granular alumina carrier) was gently flowed down from the substantially central portion directly above the concave portion of the circular flat-bottomed glass pan, the granular catalyst was dead by its own weight. It was observed that it spreads in the shape of a cone, i.e., a mountain, and has a mountain at substantially the same angle with respect to the horizontal plane. It was the same even when the catalyst particle diameter was changed.

  FIG. 6 is a diagram showing the experimental situation. FIG. 6A shows the case where the diameter of the catalyst particles is 2 mmφ (φ = diameter, the same applies hereinafter), and FIG. 6B shows the case where the diameter of the catalyst particles is 3 mmφ. . When the inclination angle was measured with respect to the horizontal plane, the angle was approximately 30 deg (θ) regardless of the diameter of the catalyst particles. This result can be used as a guide when setting the inclination angle for the swelled portion in the present invention.

<Experiment 2: Experiment related to change in shape of upper surface of catalyst in horizontal container filled with granular catalyst>
When a horizontal type container filled with a granular catalyst or a granular adsorbent, such as a reformer or a desulfurizer, is used for a long time, the catalyst particles or adsorbent particles are crushed and become finer as shown in FIG. Clogging occurs (granulation progresses more in the lower layer catalyst). Therefore, as shown in FIG. 11 (a), the gas initially flows in the catalyst or the adsorbent, but as time passes, a space is formed above, and as shown in FIG. 11 (b), the gas flows into the space. Shortcuts occur, and the reforming effect and desulfurization effect are significantly reduced with time.

  Experiment 2 is an experiment for confirming such a situation and fact, and corresponds to the precursor experiments of Experiments 3 to 5 described below. FIG. 7 is a diagram for explaining Experiment 2. In this experiment, the powdery and dense portion was slid down in a simulated manner to observe the state of voids on the upper surface of the catalyst layer. FIG. 7 shows a state seen from the front side, but if shown in a perspective view, it is the same as FIG.

  In FIG. 7, the container 1 is a lid-like container having no bottom surface, and gripping members 3 and 4 are provided on the left and right. The bottom plate 2 is a bottom plate that fits on the side of the container 1 that does not have a bottom surface and is slidable in the vertical direction. In a state where the container 1 is fixed by the gripping members 3 and 4, the granular catalyst is packed inside, and the bottom plate 2 is attached. The bottom plate 2 is placed on a table that can move in the vertical direction, and the bottom plate 2 can be slid in the vertical direction with respect to the container 1 by moving the table up and down. At first, the bottom plate 2 was pushed upward until the upper surface of the catalyst hits the upper surface of the container 1, and then the bottom plate 2 was gradually slid downward to observe the shape change of the upper surface of the catalyst.

  As a result, as shown in FIG. 7B, the upper surface of the catalyst descends while maintaining its shape, and a gap is formed in the upper part of the upper surface of the catalyst, and a shortcut path is formed by this gap. The same was true when the particle size of the catalyst particles was 2 mmφ and 3 mmφ.

<Experiment 3: Experiment concerning change in shape of top surface of catalyst when "swelling part" is provided in conventional granular catalyst-filled horizontal container (part 1)>
Experiment 3 is an experiment related to a change in shape of the upper surface of the catalyst when a “swelled portion” is provided in a horizontally placed container in which the granular catalyst is filled inside the container. 8A and 8B are diagrams for explaining Experiment 3. FIG. 8A shows the case where the diameter of the catalyst particles is 2 mmφ, and FIG. 8B shows the case where the diameter of the catalyst particles is 3 mmφ.

  In Experiment 3, the inclination angle of the “swelled portion”, that is, the angle with respect to the horizontal was 20 deg (α = 20θ). The other points are the same as those in Experiment 2 and FIG.

  In a state where the container 1 is fixed by the gripping members 3 and 4, the granular catalyst is packed inside, and the bottom plate 2 is attached. The bottom plate 2 is placed on a table that can move in the vertical direction, and the bottom plate 2 can be slid in the vertical direction with respect to the container 1 by moving the table up and down. At first, the bottom plate 2 was pushed upward until the upper surface of the catalyst hits the entire upper surface of the container 1, that is, the inclined upper surface, and then the bottom plate 2 was gradually slid downward to observe the shape change of the upper surface of the catalyst.

  As a result, as shown in the lower view in FIG. 8 (a) and the lower view in FIG. 8 (b), the upper surface of the catalyst spreads only slightly in the lateral direction. It was observed that voids were formed at approximately equal intervals between them. The same was true when the diameter of the catalyst particles was 2 mmφ and 3 mmφ.

<Experiment 4: Experiment concerning change in shape of catalyst upper surface in the case where "conical section" is provided in a conventional horizontal catalyst-filled horizontal type container (part 2)>
Experiment 4 is an experiment related to a change in the shape of the upper surface of the catalyst in the case where a “swelled portion” is provided in a horizontally placed container in which the granular catalyst is filled inside the container, as in Experiment 3. 9A and 9B are diagrams for explaining Experiment 4. FIG. 9A shows the case where the diameter of the catalyst particles is 2 mmφ, and FIG. 9B shows the case where the diameter of the catalyst particles is 3 mmφ.

  In Experiment 4, the inclination angle of the “swelled portion”, that is, the angle with respect to the horizontal was 30 deg (α = 30θ). The other points are the same as in Experiments 2 to 3 and FIGS. As a result, it was observed that the upper surface of the catalyst spreads in the lateral direction and the voids gathered at the top, as shown in the lower view in FIG. 9A and the lower view in FIG. 9B. The same was true when the diameter of the catalyst particles was 2 mmφ and 3 mmφ.

<Experiment 5: Experiment (No. 3) concerning the shape change of the upper surface of the catalyst in the case where a “swelled portion” is provided in a conventional horizontal catalyst-filled horizontal container>
Experiment 5 is an experiment related to a change in the shape of the upper surface of the catalyst in the case where a “swelled portion” is provided in a horizontally placed container in which the granular catalyst is filled inside the container, as in Experiments 3 to 4. 10A and 10B are diagrams for explaining Experiment 5. FIG. 10A shows the case where the diameter of the catalyst particles is 2 mmφ, and FIG. 10B shows the case where the diameter of the catalyst particles is 3 mmφ.

  In Experiment 5, the inclination angle of the “swelled portion”, that is, the angle with respect to the horizontal was 40 deg (α = 40θ). Other points are the same as those in Experiments 2 to 4 and FIGS. As a result, as shown in the lower view in FIG. 10 (a) and the lower view in FIG. 10 (b), the upper surface of the catalyst greatly spreads in the lateral direction, and the voids gather at the top. The shortcut path is only at the top, and is greatly shortened compared to the case of α = 0θ and α = 20θ. The same was true when the diameter of the catalyst particles was 2 mmφ and 3 mmφ.
