The development experience of irregular shape catalyst carrier is from traditional spherical, Ring-cylindrical, to five holes, seven apertures in the human head, nine holes, the multi-through hole cylindricality such as 24 holes, the clover of the current international practice, bunge bedstraw herb shape from petroleum refining industry, tooth by now spherical (having another name called celestial being spherical), and miniature spherical (Φ 1 ~ 2mm).For hydrofinishing and hydrocracking catalyst reaction, because reactant is large hydrocarbon molecules, therefore the impact of the diffusion couple catalytic reaction of reactant is very large, and the speed therefore improving diffusion is favourable to raising reaction speed.In general, catalyst external surface is long-pending larger, and the hydrogenation activity of catalyst is higher.
The profile of Hydrobon catalyst, by bead or bar shaped, develops into clover and the bunge bedstraw herb shape of today, main just for increasing the external surface area of catalyst and shortening the length in duct, thus is conducive to reacting the restriction breaking away from diffusion.And the spherical improvement can regarding roughly the leafy careless shape of equal length as of celestial being, considerably increase the external surface area of catalyst, to heat transfer, mass transfer advantageously, catalyst can be made to have given play to larger usefulness.
Now commercially mainly apply the machine for making pill of the field of Chinese medicines to produce the spherical product (see photo) of approximate celestial being.But use during machine for making pill production catalyst carrier and have following defect:
