Henan Sinmat Chemical Co., Ltd. y’emu ku zisinga okwesigika mu kukola n’okugabira zeolite catalyst hy mu China. Nga tulina obumanyirivu bungi, tukwaniriza n'ebbugumu okugula zeolite catalyst hy ey'omutindo ogwa waggulu etundibwa wano okuva mu kkolero lyaffe. Tukwasaganye okufuna sample ya bwereere.
Okwanjula
Zeolite catalyst HY (Hydrogen Y) oba HY molecular sieve kika kya protonic Y-type zeolite efunibwa nga tukyusa NaY zeolite okuyita mu ammonia ion exchange ne calcination dealumination. Era eri mu kika kya FAU structural type of zeolite, era erina pore diameter nga 0.74 nm, endabika yaayo ya butto omweru.
HY molekyu ssefuliya ekuuma ensengekera ya macroporous ey’ebitundu bisatu-ey’ekika kya Y-molekyulu. Wabula oluvannyuma lw’okuwanyisiganya ion, Na+kikyusiddwa ne kifuulibwa H+, okugiwa asidi ow’amaanyi n’omulimu gw’okutabula. Ebintu byayo ebya asidi mulimu ebifo bya asidi ebya Brønsted (B) ne Lewis (L), ebiraga emirimu egy’amaanyi ennyo mu nsengekera z’okutabula.
Nga ekitambuza ekirungo ekya bulijjo n’ekisengejja molekyu ya asidi, HY molekyu ssefuliya kye kitundu ekikulu ekikola mu katalisi z’okukutula ebirungo ebiziyiza amazzi era kikozesebwa nnyo mu kwatika kwa katalisiti y’amafuta. Era ekozesebwa nga ekinyiga eky’okusikiriza VOC n’okusikiriza piridini, oba okusiigibwa mu isomerization ne de-alkylation reactions mu chemical catalysis.
