Definitions
- the present invention relates to natural silicates of fibrous structure, plastically deformable in the presence of moisture, which contain activated carbon homogeneously dispersed within its mass.
- These new materials which have a micro, meso and macroporous texture, high adsorption capacity, high plasticity in the forming of parts and high resistance to abrasion, are especially suitable for the purification, in a dynamic regime, of fluids containing traces of undesirable compounds of relatively large molecular size.
- Activated carbons are materials of biological origin, formed mostly of carbon, which are prepared by processes that provide them with a porous structure (F. Rodriguez Reinoso, Carbon 27 (1991) 305). Its most important property is its high adsorption capacity due to its large surface area and high degree of porosity. In fact, its use for the treatment of liquids is widely known in units for the removal of colors, flavors, odors and other impurities or in solute separation processes; Likewise, its use in gas purification or vapor recovery systems is widespread, see for example Encyclopedia of Chemical Technology. Kirk-Othmer Third Edition Vol 4, p. 561-569. Wiley- Inter Science (1978).
- Activated carbons are (R.E. Franklin, Acta Cryst. 3 (1950) 107) by elementary crystals of dimensions similar to those of graphite and arranged in parallel sheets of hexagonally arranged carbon atoms. Unlike graphite, parallel planes are not perfectly arranged with respect to the perpendicular axis, so that their microporous structure is due to spaces between sheets and defects between microcrystals.
- clays that have plastic properties are known, that is to say that they are sufficiently wet, they are deformable when light pressure is applied while maintaining the shape and that they become rigid in drying and vitreous when subjected to high temperatures.
- they are natural hydrated phyllosilicates of aluminum, magnesium, iron and other elements less abundant, which in some cases contain alumina and frequently quartz and other natural components and rocks. They are composed of small particles or crystals, generally of colloidal size, which give rise to materials of great surface development with capacity for both physical adsorption and chemical interaction.
- These small particles in general, are configured as a set of lamellae or microplates, although they can also occur in fibrous structures, such as atapulgite and sepiolite. This fibrous structure gives the aforementioned materials certain properties that are not observed in clays configured by lamellae.
- Sepiolite is found in nature mainly in two forms: ⁇ -sepiolite or parasepiolite that appears as large beams or sheaves of crystalline fibers and ⁇ -sepiolite that takes the form of amorphous aggregates, small rounded sheets or rods.
- sepiolite can adopt several macroscopic aspects (compact, spongy, fibrous, etc.).
- the shape of sepiolite is very important in relation to its possible applications. Take as an example U.S. Patent 4,266,672 describing a process for cracking hydrocarbons with a sepiolite-containing catalyst whose configuration must inexcusably be in the form of rods to achieve the desired catalytic action.
- Sepiolite is a naturally occurring hydrated magnesium silicate for which various structural formulas have been proposed, such as Si ⁇ Mg 8 O 30 (OH) 4 -8H 2 O with stoichiometric variations in the number of protons, surface hydroxyl groups and Crystallization water molecules depending on their origin and subsequent purification treatments. They have a fibrous structure consisting of talc type tapes parallel to the fiber axis with two layers of tetrahedral units of silica attached to a layer of octahedral units of magnesium through oxygen atoms. Its alternating arrangement determines the presence of channels oriented to the direction of the fiber whose section is 3.6 x 10.6 ⁇ . More detailed information can be found in the review carried out by A.
- the material is arranged in sheets or parallel plates, or preferably it is formed in structures perforated along the longitudinal axis by multiple parallel channels that are called monoliths.
- the pressure drop or pressure drop that causes the passage of gases through the adsorbent formed in this way is two or three orders of magnitude lower than that which occurs when conventional beds of particles are used, see for example De Luca JP and Campbell, L.E. Adv. Mat. Cat., 293 (1977).
- These structures have their greatest application in the catalytic converters of gasoline cars, although their use has been extended in recent years to other industrial applications and especially to the design and operation of adsorption units.
- the current state of the art contemplates three processes for the preparation of monoliths of adsorbent material, all based on activated carbon: a) the formation of activated carbon powder is carried out with the help of organic or inorganic binders; b) the monolith is prepared from precursors of activated carbon previously formed; c) activated carbon is deposited on previously configured structures.
- the material that is obtained maintains the microporous structure of activated carbon (pore diameter between 0 and 2 nm) and, therefore, has severe limitations for the dynamic adsorption of compounds whose molecular volume is relatively large.
- the plastic and textural properties of natural silicates of fibrous structure are combined with those derived from the microporous nature of activated carbons, in order to obtain micro, meso and macroporous materials of high surface performance, high mechanical strength and easily conformable .
- the object of the present invention is to obtain materials with high surface performance, resistant to breakage and abrasion and easily conformable, by integrating the plastic and textural properties of natural silicates of fibrous structure with the characteristics of activated carbon.
- the surface available for adsorption depends on the size of the adsorbate molecule and the pore diameter of the adsorbent material; if it is intended to adsorb large molecules, it is of greater interest to have adsorbents with adequate pore diameter.
- the intimate mixture of the aforementioned components has a double effect: a) it results in materials that have a slight increase in specific surface area and a greater volume of meso and macropores when compared with the values that would correspond to the starting products taking count your percentages in the mix; b) the activated carbon integrated in the dough limits the volume reduction that normally occurs when a wet piece of silicate is subjected to drying and subsequent heat treatment.
- the natural sepiolite used in this invention is ⁇ -sepiolite in a compact form, commercially known as Sepiolite of Vallecas, whose typical impurity content is as follows: Al 2 O 3 : 2.6%; Fe 2 O 3 : 0.3%; K 2 O: 0.6%; CaO: 0.9%; Na 2 O: 0.1%.
- sepiolite and activated carbon are preferably mixed dry and homogeneously; Subsequently, the mixture is kneaded with water in a high shear kneader.
- the elementary acicular particles of sepiolite are normally found forming beams.
- this new mass is arranged in parallel sheets or plates or preferably it is formed in structures perforated by parallel channels along its longitudinal axis - monoliths - materials with high surface performance and highly resistant to abrasion are obtained, which allow the treatment of large volumes of gases with minimal pressure losses.
- these materials can be subjected to high temperature heat treatments in an air atmosphere to remove activated carbon by combustion and thus obtain ceramic structures of controlled porosity.
- a commercially activated carbon sawdust carbon which has a moisture content of 3% by weight, an ash content of 8.5% by weight, an apparent density of 0.45 g / cm 3 , pH of 9, a specific surface area of 1200 m 2 / g and a total pore volume of 0.62 mL / g measured with N 2 according to the BET method and a total pore volume with a diameter greater than 8 nm of 0.05 mL / g measured by mercury intrusion.
- sepiolite from Vallecas is treated at 270 ° C for 3 hours; it has a specific surface area of 250 m 2 / g and a total pore volume of 0.42 mL / g measured with N 2 according to the BET method and a total pore volume with a diameter greater than 8 nm of 0.64 mL / g measured by mercury intrusion.
- 1 kg of dried sepiolite with particle size less than 0.1-0.3 mm is mixed with 1 kg of dry active carbon with particle size less than 0.1 mm. Once a mixture is obtained homogeneous, this is taken to a double sigma kneader and kneading begins by slowly adding deionized water; After the addition of water, kneading is maintained for 4 hours.
- the mass thus obtained is formed by an extruder to obtain a parallelepiped perforated by parallel channels along the longitudinal axis of external dimensions of 5x5x100 cm.
- the cross section of the channels is square with dimensions of 0.25 x 0.25 cm and wall thickness of 0.09 cm and has a geometric surface of 8.65 cm 2 / cm 3 . These shaped pieces are air dried for 24 hours and subsequently treated at 270 ° C for 3 hours in an air atmosphere.
- the monoliths obtained have a rupture pressure of 150 Kg / cm 2 and high abrasion resistance (3000 hours of air passing through them at room temperature at a linear speed of 7 m / s without the least weight loss).
- the decrease in size observed in relation to the green monolith is 8% on any axis when treating at 270 ° C.
- they In relation to their texture, they have a specific surface area of 760 m 2 / g and a total pore volume of 0.72 mL / g measured with N 2 according to the BET method and a total pore volume with a diameter greater than 8 nm of 0, 55 mL / g measured by mercury intrusion.
- the acetone adsorption-desorption experiments are carried out in a dynamic regime system containing an adsorbent monolith with 21 cells, a length of 26.8 cm and a weight of 35.15 g.
- An air flow of 4 liters / minute, at 25 ° C and atmospheric pressure, containing 0.24 mg of acetone / minute and gram of adsorbent is fed to this system.
- the entire acetone is adsorbed; From this time on, a progressive decrease in adsorption rate is observed, which is 0.22 mg / min per gram of adsorbent at 7 hours and 0.10 mg / min per gram of adsorbent at 10 hours of operation. .
- Saturation of the adsorbent occurs after 13 hours of testing, the amount adsorbed 0.10 g of acetone / g of adsorbent.
