Ama-molelisalar sieveszisetshenziswa kabanzi kwizimboni zamakhemikhali neze-petrochemical zokuhlukaniswa okuhlukahlukene kanye nezinqubo zokuhlanza. Enye yezicelo zabo ezibalulekile ekuhlanzeni kwegesi ye-hydrogen. I-Hydrogen isetshenziswa kabanzi njenge-feedstock ezinhlokweni ezahlukahlukene zezimboni, njengokukhiqizwa kwe-ammonia, methanol kanye namanye amakhemikhali. Kodwa-ke, i-hydrogen ekhiqizwa yizindlela ezahlukahlukene ayihlali ihlanzekile ngokwanele ngalezi zicelo, futhi idinga ukuhlanzwa ukuze kudalule ukungcola okufana namanzi, isikhutha, namanye amagesi. Amavie amahle aphumelela kakhulu ekususeni lokhu kungcola okuvela emifudlaneni yegesi ye-hydrogen.

Ama-molelisalar sieves ayizinto zokwenziwa ezinamandla akwazi ukukhetha ama-molecule akhethe ama-adsorb asuselwa kusayizi nokwakheka kwawo. Ziqukethe uhlaka lwemithambo exhumekile noma ama-pores angosayizi kanye nokwakheka okufanayo, okubavumelayo ukuthi bakhethe ama-molecule alungile angena kule mikhakha. Usayizi wemithambo ungalawulwa ngesikhathi sokuhlanganiswa kwesihlungo se-molecular, esenza sikwazi ukuvumelanisa izakhiwo zazo ngezinhlelo ezithile.

Endabeni yokuhlanzwa kwe-hydrogen, kusetshenziswa ama-molefanelar sieves ukuze kukhethwe amanzi e-adsorb kanye nokunye ukungcola okuvela emfuleni igesi ye-hydrogen. Ama-molecular ama-adenges ama-molecule wamanzi nokunye ukungcola, ngenkathi kuvumela ama-molecule we-hydrogen ukuba adlule. Ukungcola okwenziwe ama-adsorbed kungase kuhlaselwe udutshulwe kusuka kusihlungo se-molecular ngokukushisa noma ngokuzihlanza ngomfula igesi.

Okusetshenziswa kakhuluisihlungo se-molecularUkuhlanzwa kwe-hydrogen kuwuhlobo lwe-zeolite olubizwa nge-3A zeolite. Le zeolite inosayizi we-pore of 3 angstroms, okuvumela ukuthi ikhethe amanzi adsorb nokunye ukungcola okunosayizi omkhulu wamangqamuzana kune-hydrogen. Kukhethile futhi kumanzi, okwenza kube yimpumelelo ekususeni amanzi emfuleni we-hydrogen. Ezinye izinhlobo zeZeolites, ezinjenge-4a nezalites, nazo zingasetshenziselwa ukuhlanzwa kwe-hydrogen, kepha zikhethe kancane kumanzi futhi zingadinga amazinga okushisa aphezulu noma izingcindezi zokukhuphuka.

Ekuphetheni, ama-molelisalar sieves aphumelela kakhulu ekuhlanzweni kwegesi ye-hydrogen. Zisetshenziswa kabanzi kwizimboni zamakhemikhali neze-petrochemical zokukhiqizwa kwegesi ehlanzekile ye-hydrogen ephezulu yezinhlelo zokusebenza ezahlukahlukene. I-3A ZEOLITE iyisihlungo esisetshenziswa kakhulu se-hydrogen ukuhlanzwa kwe-hydrogen, kepha ezinye izinhlobo zama-zeolites nazo zingasetshenziswa ngokuya ngezidingo ezithile zohlelo lokusebenza.

Ngaphandle kwama-zeolites, ezinye izinhlobo zamazwi ama-molelisar, njenge-carbon ne-silica gel ecushiwe, nazo zingasetshenziselwa ukuhlanzwa kwe-hydrogen. Lezi zinto zokwenziwa zinendawo ephezulu yendawo kanye nevolumu ephezulu ye-pore, ebenza baphumelele kakhulu ekungcoleni kwe-adderbing kusuka ekusakazweni kwegesi. Kodwa-ke, akhethe kangako kunama-zeolites futhi angadinga amazinga okushisa aphezulu noma izingcindezi zokuvuselelwa kabusha.

Ngaphezu kokuhlanzwa kwe-hydrogen,ama-molelisalar sieveszisetshenziswa nakwezinye izinsiza zokuhlukaniswa kwegesi kanye nokuhlanzwa kwezicelo. Zisetshenziselwa ukususa umswakama kanye nokungcola kusuka emoyeni, nitrogen, nakweminye imifudlana yegesi. Zisetshenziselwa futhi ukuhlukanisa amagesi ngokususelwa kusayizi wazo we-molecular, njengokuhlukaniswa komoya-mpilo kanye ne-nitrogen kusuka emoyeni, kanye nokuhlukaniswa kwama-hydrocarbons kusuka kugesi yemvelo.

Sekukonke, ama-molelisar sieves anezinto eziguquguqukayo ezinobubanzi bezicelo kwizimboni zamakhemikhali neze-petrochemical. Baqakathekile ukukhiqizwa kwamagesi ahlanzeke aphezulu, futhi banikela ngezinzuzo eziningana ngaphezu kwezindlela zokuhlukaniswa kwendabuko, njengokusetshenziswa kwamandla okuphansi, ukukhetha okuphezulu, nokusebenza kalula. Ngesidingo esandayo samagesi ahlanzekile aphezulu ezinqumweni ezahlukahlukene zezimboni, ukusetshenziswa kwama-molefanelar sieves kulindeleke ukuthi kukhule ngokuzayo.
