Amakhemikhali e-Petrochemicals3

Ngaphezu kwe-hydrogen sulfide, igesi yokuqhekeka kwe-petroleum ngokuvamile iqukethe inani elithile le-organic sulfur.Isihluthulelo sokunciphisa okuqukethwe kwesulfure ukukhishwa okusebenzayo kwesibabule utshwala ne-hydrogen sulfide kugesi eluhlaza.Isisefo se-molecular singasetshenziselwa ukukhangisa ezinye izinhlanganisela ezinesulfure.Umgomo we-adsorption ikakhulukazi uhlanganisa izici ezimbili:

1- ukukhethwa komumo kanye ne-adsorption.Kunemigudu eminingi yokuvula iyunifomu esakhiweni se-molecular sieve, engahlinzeki nje kuphela indawo enkulu yangaphakathi, kodwa futhi ikhawulela ingxenye yama-molecule anendawo enkulu yokungena.

I-2- i-polar adsorption, ngenxa yezimpawu ze-ion lattice, indawo ye-molecular sieve i-polarity ephezulu, ngaleyo ndlela inamandla okukhangisa ama-molecule angenayo i-unsaturated, i-polar molecule kanye nama-molecule ahlukaniswe kalula.Isisefo samangqamuzana sisetshenziswa kakhulu ukususa i-thiol kugesi yemvelo.Ngenxa ye-polarity ebuthakathaka ye-COS, efana nesakhiwo samangqamuzana e-CO2, kukhona ukuncintisana phakathi kwe-adsorption kusihlungo se-molecular phambi kwe-CO2.Ukwenza inqubo ibe lula futhi kuncishiswe ukutshalwa kwezimali kwemishini, i-molecular sieve adsorption sulfate imvamisa isetshenziswa ngokuhambisana ne-molecular sieve dehydration.

Imbobo ye-JZ-ZMS3, JZ-ZMS4, JZ-ZMS5 kanye ne-JZ-ZMS9 i-molecular sieve ingu-0.3nm, 0.4nm, 0.5nm kanye no-0.9nm.Kwatholakala ukuthi i-JZ-ZMS3 i-molecular sieve ayimunca neze i-thiol, i-JZ-ZMS4 i-molecular sieve imunca umthamo omncane kanye ne-JZ-ZMS9 i-molecular sieve imunca kakhulu i-thiol.Imiphumela ibonisa ukuthi amandla e-adsorption kanye nezakhiwo ze-adsorption ziyakhula njengoba imbobo ikhula.
