- GTL gas to liquids
- hydrocarbons obtained by this FT reaction are a wide range of hydrocarbons ranging from methane to wax and trace amounts of oxygen-containing compounds such as various alcohols, and cannot selectively produce a specific fraction. Therefore, for example, in order to efficiently obtain a kerosene fraction by the FT reaction, in addition to the straight kerosene fraction produced by the FT reaction, a heavier wax fraction is hydrocracked. It is common practice to produce a kerosene fraction and increase the yield of the kerosene fraction.
- gasoline fraction can also be obtained by FT reaction.

- the octane number of hydrocarbons is the highest for aromatic hydrocarbons, and then decreases in the order of naphthenic hydrocarbons, olefinic hydrocarbons, and paraffinic hydrocarbons.
- the conventional one-stage method has a problem that both reactions cannot be performed efficiently because the optimum reaction temperature ranges of the FT synthesis catalyst and the solid acid catalyst are different.
- the reaction when the reaction is carried out at a relatively low temperature that is optimal for an FT synthesis catalyst, the production of lower hydrocarbons such as CH 4 is suppressed and higher hydrocarbons having 5 or more carbon atoms are efficiently produced.
- the activity of the catalyst is low, the decomposition and isomerization reaction of the produced hydrocarbons are lowered, the gasoline yield is lowered, and the production of high octane hydrocarbons such as aromatic hydrocarbons and branched hydrocarbons is also lowered.
- the reaction when the reaction is carried out at an optimum temperature for the solid acid catalyst, the FT reaction promotes the generation of gas components such as lower hydrocarbons such as CH 4 and CO 2, resulting in a decrease in gasoline yield. .
- the reaction can proceed at the optimum temperature of each catalyst, and a gasoline fraction can be produced efficiently.
- the cost of the process is increased and hydrogenolysis is carried out by introducing hydrogen before the second stage reaction, isoparaffin in the product is produced, but the olefin content is reduced, and the octane number is reduced.

Compared with the method of producing gasoline fractions from synthetic gas, high activity, less generation of gas components, rich in aromatics, naphthenes, olefins and branched paraffins can be produced. As a result, the present invention has been completed.

Manganese carbonate as the FT synthesis catalyst component according to the present embodiment must be present in the form of a carbonate, and manganese oxide cannot provide the effects of the present embodiment. On the other hand, if the firing temperature is too low, activation of the FT active metal species cannot be achieved, which is not preferable.
- the drying and baking time is not generally determined depending on the processing amount, but is usually 1 to 10 hours. If the treatment time is less than 1 hour, the transpiration of moisture may be insufficient, and the activation of the FT active metal species is diluted, which is not preferable.

- synthesis gas can be passed through the catalyst composition according to the present embodiment reduced as described above.
- the synthesis gas used may be mainly composed of hydrogen and carbon monoxide, and other components may be mixed as long as the reaction is not hindered.

- the types of biomass in this case include agricultural, forestry and fishery resource biomass such as food, building materials and pulp, waste biomass such as agriculture, forestry and livestock waste, and plantation biomass such as sugar cane, palm palm and seaweed. Among them, it is preferable to use unused waste biomass that does not compete with food.
- biomass gasification method include various types such as direct gasification, indirect gasification, atmospheric pressure gasification, and pressurized gas.
- Gasification furnace types include a fixed bed, a fluidized bed, and a spouted bed. In the method for producing hydrocarbons using the catalyst composition according to the present embodiment, biomass gasified using any of these methods may be used.
- the reaction rate (k) depends on the hydrogen partial pressure in the first order
- the partial pressure ratio of hydrogen and carbon monoxide (H 2 / CO molar ratio) is desirably 0.6 or more. Since this reaction is a reaction accompanied by volume reduction, it is preferable that the total value of the partial pressures of hydrogen and carbon monoxide is higher.
- the partial pressure ratio between hydrogen and carbon monoxide varies depending on the type of raw material and the gasification method in biomass gasification described above, but the upper limit is not particularly limited in the present embodiment.
- 0.6 to 2.7 is appropriate, preferably 0.8 to 2.5, and more preferably 1 to 2.3. If the partial pressure ratio is less than 0.6, the yield of the generated hydrocarbons tends to decrease, and if the partial pressure ratio exceeds 2.7, the generated hydrocarbons tend to increase in gas components. It is done.
- carbon dioxide to be coexisted in the synthesis gas for example, those obtained from a reforming reaction of petroleum products or natural gas can be used without any problem.

- the catalyst composition according to the present embodiment is obtained by directly synthesizing a synthesis gas containing carbon dioxide obtained by reforming natural gas by a self-thermal reforming method or a steam reforming method without decarboxylation treatment. It can also be made to react by making it ventilate. By subjecting the synthesis gas containing carbon dioxide to the reaction as it is, it is possible to reduce the equipment construction cost and operation cost required for the decarboxylation treatment, and it is possible to reduce the production cost of the resulting hydrocarbons.
- the total pressure of the synthesis gas (mixed gas) to be subjected to the reaction is preferably 0.3 to 10 MPa, more preferably 0.5 to 7 MPa, and further preferably 0.8 to 5 MPa.
- Low pressure is not preferable because chain growth becomes insufficient and the yield of gasoline, kerosene, wax, etc. tends to decrease.
- the higher the partial pressure of hydrogen and carbon monoxide the more advantageous.
- the higher the partial pressure the more expensive the plant construction costs, and the larger the compressors required for compression, the higher the operating costs. Tend to rise. Therefore, the upper limit of the partial pressure is restricted from an industrial viewpoint.
- the contact time of the synthesis gas and the catalyst in the FT reaction (hereinafter referred to as W / F: weight / flow [g ⁇ h / mol]) is preferably 1 to 100, more preferably 1.5 to 90, still more preferably 2 to 80.
- W / F weight / flow [g ⁇ h / mol]
- W / F weight / flow [g ⁇ h / mol]
- the H 2 / CO molar ratio of the synthesis gas is the same, the lower the reaction temperature, the higher the chain growth probability and C 5 + selectivity (selectivity for synthesis of hydrocarbons having 5 or more carbon atoms). Increases, but the CO conversion decreases. Conversely, if the reaction temperature increases, the chain growth probability and C5 + selectivity decrease, but the CO conversion increases. Also, the higher the H 2 / CO ratio, the higher the CO conversion rate, the lower the chain growth probability and C5 + selectivity, and vice versa when the H 2 / CO ratio is low. The effect of these factors on the FT reaction varies depending on the type of catalyst used.
- the reaction temperature is 230 to 350 ° C., and 240 to 310 ° C. is used. Preferably, 250 to 300 ° C is more preferable. If the reaction temperature is 230 ° C. or higher, both the FT synthesis catalyst and the zeolite work effectively, and it becomes possible to produce a high-octane gasoline fraction by the generation of hydrocarbons and their decomposition and isomerization reactions. . In addition, by setting the reaction temperature to 350 ° C. or lower, it is possible to suppress generation of undesirable gas components on the FT synthesis catalyst and to suppress generation of gas components due to overdecomposition on zeolite. In addition, CO conversion rate and the selectivity of various products are defined by the following formula.
- CO conversion rate [(number of moles of CO in raw material gas per unit time) ⁇ (number of moles of CO in outlet gas per unit time)] / (number of CO moles in raw material gas per unit time) ⁇ 100

本実施形態に係る触媒組成物は、炭酸マンガン及びFT活性金属種を含有する1種以上のFT合成触媒と、固体酸を示すゼオライトとを含有するものである。
本実施形態において用いられるFT合成触媒は、1種以上のFT活性金属種と炭酸マンガンとを含有する。
本実施形態の触媒組成物は、炭酸マンガンとFT活性金属種とを含有する1種以上のFT合成触媒、及び固体酸を示すゼオライトを含有する。
本実施形態の触媒組成物を構成するFT合成触媒中に含有されるFT活性金属種としては、ニッケル、コバルト、鉄、ルテニウムが挙げられる。中でも、より高活性な金属種としてルテニウムやコバルトが好ましく選択される。また、これらの金属種は単独で用いることも可能であり、2種以上を複合させて用いることも可能である。
本実施形態の炭化水素類の製造方法は、上記FT合成触媒を用いて、合成ガスから炭化水素類を合成するFT反応と、FT反応により得られた炭化水素類を、固体酸を示すゼオライトに接触させる変換反応とを有する。炭化水素類をゼオライトに接触させると、分解反応や異性化反応等の様々な反応により、炭化水素類が変換される。その結果、ガソリン留分が増大すると推察される。
この還元処理により、触媒が反応において所望の触媒活性を示すように活性化される。この還元処理を行わなかった場合には、FT活性金属種が十分に還元されず、所望の触媒活性を示さない。還元処理温度は、140~350℃が好ましく、150~300℃がより好ましい。140℃未満では、FT活性金属種が十分に還元されず、十分な反応活性が得られない。また、350℃を大幅に超える高温では、触媒成分の炭酸マンガンの酸化マンガンへの分解が進行して活性低下を招く可能性が高くなる。

触媒Aに対する合成ガス(H2+CO)の接触時間(W/F:weight/flow[g・h/mol])は約13.4g・h/molであった。なお、混合したH-ZSM-5はFT反応に対して全く活性を示さないことから、W/Fは、触媒A中のFT合成触媒である触媒aに対する合成ガスの接触時間で表している。反応結果及びこの時得られた生成物の組成分析結果を表1及び図1に、さらに生成物の炭化水素タイプ別分析結果を表2に、それぞれ示す。
