Surface acidity yeZSM molecular sieve

Iyo acidity yepamusoro yeZSM molecular sieve ndechimwe chezvinhu zvayo zvakakosha sechinhu chinokonzera.
Iyi acidity inobva kumaatomu ealuminium ari mumolecular sieve skeleton, iyo inogona kupa mapurotoni kuti aumbe nzvimbo ine protonated.
Iyi protonated surface inogona kutora chikamu mune zvakasiyana siyana zvemakemikari kuita, kusanganisira alkylation, acylation, uye kupera mvura. Iyo acidity yepamusoro yeZSM molecular sieve inogona kudzorwa.
Iyo acidity yepamusoro yemolecular sieve inogona kudzorwa nekugadzirisa masisitimu mamiriro, akadai seSi-

Al ratio, tembiricha ye synthesis, mhando ye template agent, etc. Mukuwedzera, iyo acidity yepamusoro ye molecular sieve inogonawo kuchinjwa ne-post-therapy, senge ion exchange kana oxidation kurapwa.
Iyo acidity yepamusoro yeZSM molecular sieve ine mhedzisiro yakakosha pakuita kwayo uye kusarudza sechinhu chinokonzeresa. Kune rimwe divi, acidity yepamusoro inogona kusimudzira activation ye substrate, nekudaro ichimhanyisa chiyero chekuita.
Kune rimwe divi, acidity yepamusoro inogonawo kukanganisa kugoverwa kwechigadzirwa uye maitiro ekuita. Semuenzaniso, mune alkylation reactions, ma molecular sieves ane high acidity yepamusoro anogona kupa zvirinani alkylation selectivity.
Muchidimbu, iyo acidity yepamusoro yeZSM molecular sieve imwe yeayo akakosha hunhu sechikonzero.
Nekunzwisisa uye kudzora iyi acidity, zvinokwanisika kukwidziridza kuita kwema molecular sieves mune akasiyana makemikari maitiro.
