Henan Sinmat Chemical Co., Ltd. ke e mong oa bahlahisi le barekisi ba tšepahalang ba zeolite catalyst ssz-13 naheng ea China. Ka boiphihlelo bo bongata, re u amohela ka mofuthu hore u reke zeolite catalyst ssz-13 ea boleng bo holimo e rekisoang mona fekthering ea rona. Ikopanye le rona bakeng sa sampole ea mahala.

SSZ-13 catalyst, ke mofuta oa CHA structure molecular sieve e nang le masoba a ikhethang a robeli-e leng litho tsa ring ring, 'me ke e 'ngoe ea li-sieve tsa bohlokoa ka ho fetisisa tsa limolek'hule tsa tlhabollo ea tikoloho, haholo-holo ho diesel exhaust denitrification (SCR). SSZ-13 e fetohile maemo a indasteri ho li-catalyst systems tsa NH₃-SCR.
SSZ-13 molecular sieve e na le-dimensional cross{4}}sistimi ea sebopeho sa pore, e lumellang NH₃, NO, le NO₂ ho kena ha e ntse e sitisa ho kena ha SO₂ oxides le hydrocarbons tse kholo, kahoo e bontša ho hanyetsa chefo. Bokahare ba eona bo na le li-cage tse tloaelehileng tsa CHA, tse tiisang li-ion tsa tšepe tse kang Cu²⁺ le Fe³⁺ ka har'a mekotla ena, e leng lebaka la mantlha la ho hanyetsa botsofali ba hydrothermal le botsitso ba mocheso o phahameng.
SSZ-13 SCR catalyst ke sesebelisoa se atlehileng ka ho fetesisa sa ho hlakisa khase ea exhaust kajeno, ke sieve e khethehileng ea molek'hule e etselitsoeng NH₃-SCR. Ka lebaka la botsitso ba eona bo botle ba hydrothermal le sebaka se phahameng se ikhethileng, e boetse e bonts'a ts'ebetso e ikhethang ho methanol ho olefins (MTO) le karohano ea khase ea adsorption.
