Enwere ike ikewa paraffins linear na alaka ya site na sieve molecular zeolite. Paraffins nwere ngwa na ụkpụrụ dị iche iche na petrochemicals na kemịkalụ dị mma nke ala, na nkewa nke linear na paraffins nwere ike nweta nrụpụta ọrụ ụlọ ọrụ dị elu yana uru akụ na ụba.
Kedu ihe kpatara iji kewaa Linear na Paraffins alaka?
Linear paraffins (nke a makwaara dị ka alkanes nkịtị ma ọ bụ n {{0}paraffins) na paraffins alaka (nke a na-akpọkwa alkanes isomeric ma ọ bụ i{1}paraffins) bụ ihe dị mkpa maka akụrụngwa na ụlọ ọrụ petrochemical, na nkewa ha dị oke mkpa maka mmepụta mmanụ ọkụ na akụrụngwa kemịkal.
Maka paraffins linear, ha nwere isi ihe na-esi esi elu yana ọnụọgụ octane dị ala (mgbochi - arụmọrụ mgbawa). Ha dabara nke ọma dị ka akụrụngwa kemịkal, dị ka mgbawa iji mepụta ethylene na propylene, na-emepụta ihe ndị na-emepụta ihe, na-akwadebe ihe mgbaze alkane nkịtị na kemịkalụ pụrụ iche, wdg.
Maka paraffins nwere alaka, ha nwere isi ihe na-esi nri dị ala, ọnụọgụ octane dị elu, yana ọkụ zuru oke. Ha dabara nke ọma dị ka ihe mmanụ ụgbọala, dị ka mmanụ ụgbọala na-agwakọta iji mụbaa nọmba octane, mmanụ ụgbọ elu, na mmanụ dị ọcha, wdg.
Kedu ka esi ekewapụta paraffins Linear na alaka?
Dị ka a maara, dayameta dị oke egwu nke mkpụrụ ndụ paraffin linear bụ 4.9 angstroms, ebe dayameta nke paraffin nwere alaka karịrị angstroms ise. Ya mere, anyị nwere ike iji mmetụta siri ike nke ụdị 5A zeolite molecular sieves iji kewaa paraffins linear na branched.
Paraffins nkịtị (dị ka n-butane na n{1}hexane) nwere usoro ahịrị ma pere mpe ma dị gịrịgịrị n'ogo, yabụ na ha nwere ike ịbanye n'oghere nke ụdị 5A molecular sieve. Na paraffins isomeric (dị ka iso{4}}butane na iso{{5}hexane) nwere akụkụ alaka, mpịakọta molekụla buru ibu ma ọ bụ ọdịdị na-adịghị ahụkebe, na enweghị ike ịbanye n'oghere nke ụdị 5A molecular sieve.
Mgbe mkpụrụ ndụ paraffin na-abanye na sieves molekụla, a na-etinye paraffin nkịtị site na sieves molecular 5A; paraffins isomeric enweghị ike ịbanye na pores ma nọgide na gas ma ọ bụ mmiri mmiri. N'ụzọ dị otú a, a pụrụ ikewapụ paraffins nkịtị na paraffins isomeric site na sieves molecular 5A.
Sieves Molecular Maka ikewapụta Linear na Paraffins alaka
N'ụzọ doro anya, ụdị 5A zeolite molecular sieve dị mma maka ikewa paraffins linear na alaka. Nha pore nke 5A molecular sieve bụ ihe dị ka angstroms ise. N'ihi nnukwu nha ha na nnukwu ihe mgbochi dị elu, paraffins ndị nwere alaka enweghị ike ịbanye n'oghere nke sieve molecular 5A ma ya mere agaghị anabata ya.
Iji ụdị 5A zeolite molecular sieve kewapụ paraffins linear na alaka, nwere ike iwepụta nri nri paraffin dị ọcha dị elu (dị ka n{1}}pentane na n{2}hexane) ma kwalitekwa nhọrọ nke isomerization.
