Cire Hydrogen Sulfide da Mercaptan

Baya ga hydrogen sulfide, iskar gas mai fashewa yawanci tana ɗauke da wani adadin sulfur na halitta. Mabuɗin rage yawan sulfur shine cire sinadarin sulfur da hydrogen sulfide daga iskar gas mai ɗanɗano. Ana iya amfani da sieve na molecular don shaye wasu mahaɗan da ke ɗauke da sulfur. Ka'idar shaye-shaye ta ƙunshi fannoni biyu:

1- Zaɓar siffa da kuma shaƙa. Akwai hanyoyin buɗewa iri ɗaya da yawa a cikin tsarin sieve na ƙwayoyin halitta, waɗanda ba wai kawai suna ba da babban yanki na saman ciki ba, har ma suna iyakance adadin ƙwayoyin da ke shiga babban buɗewa.

2- Shaƙar polar, saboda halayen layin ion, saman sieve na kwayoyin halitta yana da babban polarity, don haka yana da ƙarfin sha mai yawa ga ƙwayoyin da ba su cika ba, ƙwayoyin polar da ƙwayoyin da aka raba cikin sauƙi. Ana amfani da sieve na kwayoyin halitta galibi don cire thiol daga iskar gas. Saboda raunin polarity na COS, kama da tsarin kwayoyin halitta na CO₂, akwai gasa tsakanin shaye-shaye a kan sieve na kwayoyin halitta a gaban CO₂Domin sauƙaƙa aikin da kuma rage saka hannun jari a kayan aiki, yawanci ana amfani da sulfate na shaƙar sieve na ƙwayoyin halitta tare da bushewar sieve na ƙwayoyin halitta.

Buɗaɗɗen sieve na ƙwayoyin JZ-ZMS3, JZ-ZMS4, JZ-ZMS5 da JZ-ZMS9 sune 0.3nm, 0.4nm, 0.5nm da 0.9nm. An gano cewa sieve na ƙwayoyin JZ-ZMS3 ba ya shan thiol sosai, sieve na ƙwayoyin JZ-ZMS4 yana shan ƙaramin ƙarfi kuma sieve na ƙwayoyin JZ-ZMS9 yana shan thiol sosai. Sakamakon ya nuna cewa ƙarfin sha da halayen sha suna ƙaruwa yayin da buɗaɗɗen sieve ke ƙaruwa.
