Njirimara nke particulate catalysts

Particulate catalysts nwere akụkụ elu dị elu na porosity, na-eme ka arụmọrụ mmeghachi omume dịkwuo mma. Methanol anyị {{1}to{2}}arọmatics catalysts na hydrogenation catalysts ka emebere ya n'ụdị mkpọpu, na-egosipụta nkwụsi ike na nhọrọ dị mma. N'ime ha, ngwaahịa zeolite molecular sieve nwekwara ụdị topologies dị ka FAU/MWW.

Particulate catalysts bụ otu ihe dị mkpa nke a na-ejikarị na mpaghara kemịkalụ, gburugburu ebe obibi na ike. Ụdị morphology ha pụrụ iche na arụmọrụ catalytic na-eme ka ha bụrụ akụkụ dị mkpa n'ọtụtụ usoro mmepụta ihe. Ngwa nke particulate catalysts bụ tumadi dabeere na ha elu kpọmkwem n'elu ebe, ezi dispersibility, na catalytic ọrụ, nke nwere ike budata belata ebighị ike ma melite mmeghachi omume ọnụego na selectivity na chemical Jeremaya mere.

Ọrụ catalytic nke particulate catalysts na-esite na saịtị ha na-arụ ọrụ n'elu. Saịtị ndị a nwere ike ime ka ụmụ irighiri ihe na-emeghachi omume, na-akwalite nbibi na nguzobe nke njikọ kemịkal. The particulate imewe bụghị nanị enwekwu kọntaktị ebe n'etiti catalyst na reactants kamakwa mmemmem eruba na dispersion ke reactor, na-eme ka uka nyefe arụmọrụ. Ọzọkwa, particulate catalysts na-enwekarị ike igwe dị elu, na-eguzogide iyi anụ ahụ na corrosion kemịkalụ n'oge usoro mmeghachi omume, na-agbatị ndụ ọrụ ha.
