| 中文摘要 | The so-called petroleum residue cracking gasification (RCG) process intends to convert the heavy oil first into cracked liquid by catalytic cracking and then into syngas via catalytic gasification of the cracking-formed coke. A bifunctional catalyst (BFC) was synthesized in this article and tested for the petroleum residue cracking gasification in a laboratory-scale fluidized bed reactor through comparison with the performance over an FCC catalyst. Low liquid yield of vacuum residue (VR) cracking was obtained with fresh BFC and FCC catalysts because of their strong acidity and thus activity. Hydrothermal treatment was thus performed to weaken the acidity of both the catalysts. This resulted in liquid yields of about 80 wt.% at 500 degrees C for cracking the same VR. The spent BFC and FCC catalysts were both in situ regenerated via steam gasification of the formed coke in the same fluidized bed reactor. This generated simultaneously syngas which contained CO and H-2 of up to 80 vol.%, and the realized carbon conversion was over 95% at 800 degrees C for both the catalysts. However, the regeneration time for BFC was greatly shorter than that for the FCC catalyst. This shows the much better activity of BFC for coke gasification in comparison with FCC that has almost no activity for catalyzing coke gasification. In fact, the BFC contained much more active alkaline metal sites than the FCC to ensure its catalytic activity for gasification. Crown Copyright (C) 2013 Published by Elsevier Ltd.
