Henan Sinmat Chemical Co., Ltd. y’emu ku kkampuni ezisinga okwesigika mu kukola n’okugabira zeolite catalyst sapo-34 mu China. Nga tulina obumanyirivu bungi, tukwaniriza n'ebbugumu okugula omutindo ogwa waggulu zeolite catalyst sapo-34 etundibwa wano okuva mu kkolero lyaffe. Tukwasaganye okufuna sample ya bwereere.
Okwanjula
SAPO-34 zeolite catalyst kye kimu ku bisinga obukulu ebikola catalytic mu SAPO series of molecular sieves, ye microporous silica-aluminophosphate molecular sieve. SAPO-34 erina enkola ya CHA topology framework, erimu ebiyumba bya CHA n’obutuli bw’empeta obw’ebitundu munaana, nga obunene bw’obutuli obumanyiddwa nga 3.8 Å.
Okuyingiza Si mu nsengekera ya aluminophosphate kutonda ebifo bya asidi, ne kiwa SAPO-34 byombi enkula-okulonda ekikolwa eky’ebisengejja molekyu n’omulimu gw’okutabula ogwa asidi enzigumu. Ebirungi ebikulu ebya SAPO-34 molekyu ssefuliya biri mu nsengekera yaayo ey’obutuli obutono, asidi ow’ekigero, okutebenkera okulungi mu bbugumu n’amazzi. Enkula y’obutuli obutono n’obuziba obw’ekigero biwa SAPO-34 okulonda okw’amaanyi eri olefini ezirimu kaboni omutono nga ethylene ne propylene.
SAPO-34 zeolite catalyst naddala kimanyiddwa nnyo-okukozesebwa mu nkola za methanol-ku-olefins (MTO), ezikyusa methanol mu olefins ezitaliimu kaboni omutono, okusinga ethylene ne propylene. SAPO-34 era esaanira enkola z’okukyusa methanol ezigenderera propylene, awamu n’enkyusa ezimu ez’ekirungo kya hydrocarbon catalytic, enkola z’okukyusa omwenge, oba nga catalyst oba catalyst component.
