HYDRODEOXYGENATION OF PYROLYSIS OIL AND SUBSEQUENT CO-PROCESSING AT FCC CONDITIONS FOR FUEL PRODUCTION

摘要

In this work, bimetallic Ni-Co catalyst and monometallic Ni catalyst supported on HZSM-5 were testedrnin hydrodeoxygenation of fast pyrolysis oil to further check the impact of second metal on catalytic performance. Thernbimetallic catalyst 10Ni10Co/HZSM-5 was found as the best performaning compared to corresponding monometallicrncatalysts with 39% deoxygenation degree and 37 wt% oil yield (on wet basis). To demonstrate a possible route forrnproduction of fuel from biomass, the upgraded bio-oil was subsequent co-fed with conventional feed (atmosphericrndistillation residue) at FCC conditions using a commercial micro activity test (MAT) setup. These tests showed thatrnsimilar conversion was observed for both co-processed feeds and 100% conventional feed and a reduction of heavyrncycle oil (HCO) yield and slight increase of gasoline, gas and light cycle oil (LCO) yields was found in the coprocessedrnfeeds. These findings offer a potential pathway to implement a renewable liquid fuels production from biooilrnas well as important benchmarks for fuel yields and quality.
