Inxalenye ephambili yomhlaba we-diatomaceous njengomthwali yiSiO2. Ngokomzekelo, inxalenye esebenzayo ye-industrial vanadium catalyst yi-V2O5, umgqugquzeli i-alkali metal sulfate, kwaye umthwali uhlanjululwe umhlaba we-diatomaceous. Iimvavanyo zibonisa ukuba i-SiO2 inefuthe lokuzinzisa kumacandelo asebenzayo, kwaye iqinisa ngokunyuka kwe-K2O okanye umxholo we-Na2O. Umsebenzi we-catalyst unxulumene nesakhiwo se-pore ye-dispersion ye-carr

ier. Emva kokuba i-diatomite iphathwe nge-asidi, umxholo wokungcola kwe-oxide uyancitshiswa, umxholo we-SiO2 wanda, kwaye indawo ethile yendawo kunye nevolumu ye-pore nayo yanda. Ngoko ke, umphumo we-carrier we-diatomite ococekileyo ungcono kune-diatomite yendalo.

Umhlaba we-Diatomaceous usenziwa ngokubanzi ziintsalela ze-silicate emva kokufa kwe-algae eneseli enye ngokudibeneyo ebizwa ngokuba yi-diatoms, kwaye undoqo wayo inamanzi e-amorphous SiO2. Iidiatom zinokuphila emanzini amatsha kunye namanzi anetyuwa. Kukho iintlobo ezininzi ze-diatom. Ngokuqhelekileyo, zinokwahlulwa zibe "zii-central order" diatoms kunye ne "pinnacle order" diatoms. Kuluhlu ngalunye, kukho "i-genus" eninzi, enzima kakhulu.

Inxalenye ephambili yomhlaba we-diatomaceous wendalo yi-SiO2, umgangatho ophezulu umhlophe, kwaye umxholo we-SiO2 uhlala udlula i-70%. Iidiatom ze-Monomer azinambala kwaye ziyabonakala. Umbala womhlaba we-diatomaceous uxhomekeke kwiiminerali zodongwe kunye ne-organic matter. Ukubunjwa kwe-diatom kwimithombo eyahlukeneyo yamaminerali kuyahluka.

Umhlaba we-Diatomaceous yi-fossilized diatomaceous earth deposit eyenziwe emva kokufa kwesityalo esineseli enye ebizwa ngokuba yi-diatom emva kwexesha lokuqokelela malunga ne-10,000 ukuya kwi-20,000 yeminyaka. I-Diatoms yenye yeeprotisti zokuqala ezivela emhlabeni, zihlala emanzini olwandle okanye emanzini echibi. Yile diatom ebonelela ngeoksijini emhlabeni ngephotosynthesis kwaye ikhuthaza ukuzalwa kwabantu, izilwanyana kunye nezityalo.
