Abstract

The residue cracking gasification process is intended to convert vacuum residue into light olefins by cracking and co-production the H2-rich syngas by gasifying the cracking-generated coke. In this paper, a bifunctional base catalyst is used and tested vacuum residue cracking gasification in a fluidized bed reactor in comparison with the effects over FCC catalyst and SiO2. The result shows that higher light olefins yield is produced with Ca12Al7 as the cracking catalyst in comparison with that over the FCC catalyst and SiO2. The coke over the Ca12Al7 catalyst is gasified well at 800 oC in steam. The content of H2 is about 55.5 vol% and with the content of CH4 is less than 0.2 vol% when compared to 36.6 and 2.4 vol% over the FCC catalyst, respectively.
