Ibhola yePorous Ceramic yokugquma i-catalyst kunye nezinto ezixhasayo

Inkcazelo emfutshane:

Ibhola ye-ceramic eneporous ikwabizwa ngokuba ziibhola zokucoca. Yenziwe ngokwenza i-20-30% pores ngaphakathi kweebhola ze-ceramic ezingenayo. Ngoko ke ingasetyenziselwa ukuxhasa kunye nokugquma i-catalyst, kodwa kunye nokucoca kunye nokuphelisa ukungcola okuziinkozo, i-gelatin, i-asphalting, isinyithi esinzima kunye ne-iron ion ezingaphantsi kwe-25um. Ukuba ibhola ye porous iseti kumphezulu wereactor, ukungcola okusilelayo ukukhutshwa kwinkqubo yangaphambili kunokubhengezwa kwi pores ngaphakathi kweebhola, apho khusela i-catalyst kunye nokwandisa umjikelo wokusebenza kwenkqubo. Njengoko ukungcola okukhoyo kwizinto eziphathekayo kuyahluka, umsebenzisi unokukhetha umkhiqizo ngobukhulu bawo, iipores kunye ne-porosity, okanye ukuba kuyimfuneko, yongeza i-molybdenum, i-nickel kunye ne-cobalt okanye ezinye izinto ezisebenzayo ukukhusela i-catalyst kwi-coking okanye ityhefu.
