Ọnwụ akpọnwụ akpọnwụ akpọnwụ 4A Zeolte Molecular Sieve

Nkọwa dị mkpirikpi:

Molecular sieve 4A dabara adaba maka ihicha nke gas (dịka ọmụmaatụ: gas sitere n'okike, gas petrol) na mmiri mmiri, nwere oghere nke ihe dịka 4 angstroms.

Ụkpụrụ na-arụ ọrụ nke sieves molekụla metụtara nke ọma na nha nke sieves molecular, nke bụ 0.3nm/0.4nm/0.5nm n'otu n'otu. Ha nwere ike ịgbanye ụmụ irighiri gas nke dayameta molekụla ha dị obere karịa nha pore. Ka oke nha nke pore buru ibu, ka ikike mgbasa ozi na-abawanye. Ogo pore dị iche iche, ihe ndị a na-enyocha na nkewa dị iche iche dịkwa iche. N'okwu dị mfe, sieve molekụla 3a nwere ike ịgbasa ụmụ irighiri ihe dị n'okpuru 0.3nm, sieve molecular 4a, ụmụ irighiri ihe a na-ekesa ga-enwerịrị ihe na-erughị 0.4nm, na sieve molecular 5a bụ otu ihe ahụ. Mgbe ejiri ya dị ka onye na-ekpochapụ ihe, sieve molecular nwere ike ịmịkọrọ ihe ruru 22% nke ịdị arọ ya na mmiri.

Zeolite molecular sieves nwere usoro kristal pụrụ iche mgbe niile, nke ọ bụla n'ime ha nwere usoro pore nke otu nha na ọdịdị ya, ma nwee nnukwu ebe elu. Ọtụtụ sieves molecular zeolite nwere ebe acid siri ike n'elu, ma enwere ogige Coulomb siri ike na oghere kristal maka polarization. Njirimara ndị a na-eme ka ọ bụrụ ihe na-eme ka ọ dị mma. A na-eme mmeghachi omume catalytic dị iche iche na ndị na-emepụta ihe siri ike, ọrụ catalytic na-ejikọta na nha nke pores kristal nke ihe na-eme ka ọ dị elu. Mgbe a na-eji zeolite molecular sieve mee ihe dị ka ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ onye na-ebu ibu, ọganihu nke mmeghachi omume catalytic na-achịkwa site na nha pore nke zeolite molecular sieve.
