Background technology
Solid catalyst generally is made up of carrier and catalyst activity component (coating) two parts.The key of Catalyst Production has three: one, the selection of carrier rerum natura, and as pore structure and the Acidity of Aikalinity of shape, bulk density, specific area, inside, and mechanical strength etc.The 2nd, the catalytic active component optimization of formulation, this relates to activity of such catalysts, selective and service life.The 3rd, the combination between catalytic active component and carrier and distribution.This is related to representing of active component performance and efficient.And carrier is carrying in the Catalyst Production nearly 80% workload, also is that the basis that promotes of catalyst efficiency is with crucial.
The development of irregular shape catalyst carrier has been experienced from traditional sphere, annulated column shape, to five holes, multi-through hole cylindricality such as seven apertures in the human head, nine holes, 24 holes, clover, the bunge bedstraw herb shape of the current international practice from the petroleum refining industry, tooth sphere by now (having another name called celestial being's sphere), and miniature spherical (Φ 1～2mm).For hydrofinishing and hydrocracking catalytic reaction, because reactant is big hydrocarbon molecules, so the influence of the diffusion couple catalytic reaction of reactant is very large, and the speed that therefore improves diffusion is favourable to improving reaction speed.In general, the catalyst external surface area is more big, and the hydrogenation activity of catalyst is more high.
The profile of Hydrobon catalyst develops into clover and the bunge bedstraw herb shape of today by bead or bar shaped, and main just is to increase the external surface area of catalyst and shorten the length in duct, thereby is conducive to react the restriction of breaking away from diffusion.And celestial being's sphere can be regarded the improvement of the leafy careless shape of equal length roughly as, has increased the external surface area of catalyst greatly, to conduct heat, mass transfer is more favourable, can make catalyst give play to bigger usefulness.
The main machine for making pill of using the field of Chinese medicines is produced the product (seeing accompanying drawing) of approximate celestial being's sphere on the market now.But following defective is arranged when using machine for making pill production catalyst carrier:
1. product appearance is lack of standardization.Product is rubbed with the hands the type that is cut at a high speed by the pair of metal wheel, rubs the irregular movement of cutting with the hands and makes every finished product profile all be not quite similar, and modification thing in irregular shape reaches more than 20%, influences following catalyst buildup effect.When ball was cut in stranding, tooth-like part of anything had been crushed, and caused outer surface to dwindle, and can not embody the trefoil profile advantage that contrasts.
2. limit to some extent for material.Because the requirement of some rerum natura, in the time of need be than softer material, can produce the material adhesion, moulding is obstructed.
3. can destroy the internal pore structure setting of material.Use the vibrations of screw-type extruder and machine for making pill to rub the butt formula with the hands and can produce a large amount of heat, make the chemical action aggravation of acid, delicate variation takes place in material performance, has destroyed default pore structure, easily produces the water crack phenomenon of big ratio, has influenced the performance of product.
4. contaminating impurity.Owing to learn from each other by exchanging views in the moulding at high speed vibration, higher mechanical wear is arranged, the iron in the metal, nickel plasma meeting polluted product are difficult to adapt to the catalyst prod needs that impurity is had relatively high expectations.
5. production cost is higher.The metal wheel wearing and tearing that stranding is cut are big, often need to change.Need auxiliary agent in the production process: full-bodied sesbania powder and constantly spray to stranding and cut wheel cooling and wetting ethanol etc.Thing lack of standardization is many in the semi-finished product, and the percent defective height needs extra indirect labor.
