I-Henan Sinmat Chemical Co., Ltd. ingomunye wabakhiqizi nabaphakeli abathembekile be-zeolite catalyst hy e-China. Ngolwazi oluningi, sikwamukela ngokufudumele ukuthi uthenge i-zeolite catalyst hy yekhwalithi ephezulu ethengiswa lapha embonini yethu. Xhumana nathi ngesampula yamahhala.
Isingeniso
I-Zeolite catalyst HY (Hydrogen Y) noma i-HY molecular sieve iwuhlobo lwe-protonic Y-uhlobo lwe-zeolite olutholwe ngokushintsha i-NaY zeolite ngokushintshisana kwe-ammonia ion kanye nokubala. Iphinde ibe yohlobo lwe-FAU lwesakhiwo se-zeolite, futhi inobubanzi obuyimbotshana obucishe bube ngu-0.74 nm, ukubukeka kwayo kuyimpuphu emhlophe.
I-HY i-molecular sieve igcina-isakhiwo esikhulu esiyi-dimensional esingu-Y-sohlobo lwe-molecular sieve. Kodwa-ke, ngemuva kokushintshaniswa kwe-ion, uNa+ithathelwe indawo ngu-H+, okwenza kube ne-asidi ephezulu kanye nomsebenzi okhuthazayo. Izici zayo ezine-asidi zifaka izikhungo ze-asidi i-Brønsted (B) kanye ne-Lewis (L), ebonisa umsebenzi ophezulu kakhulu ekuphenduleni kwe-catalytic.
Njengesithwali se-catalyst esivamile nesisefo samangqamuzana ane-acidic, i-HY molecular sieve iyingxenye eyinhloko esebenzayo ye-fluid catalytic cracking catalysts futhi isetshenziswa kakhulu ekuqhekekeni kwe-petroleum catalytic. Iphinde isetshenziswe njenge-adsorbent ye-VOC adsorption kanye ne-pyridine adsorption, noma isetshenziswe ku-isomerization kanye{1}}nokusabela kwe-alkylation ku-chemical catalysis.
