Hydrothermal liquefaction (HTL) is effective for converting biomass to bio-crude, but direct use of bio-crude derived from biomass HTL remains a challenge due to its low quality. In this study, Ni/HZSM-5 catalysts and zinc hydrolysis were combined to upgrade bio-crude to biofuel in HTL process. The effects of Ni/HZSM-5 and HZSM-5 on the yield and quality of bio-crude and gas were investigated. The results indicate that bifunctional Ni/HZSM-5 catalysts exhibited higher catalyst activities to improve bio-crude quality compared to HZSM-5 catalyst. Ni/HZSM-5 was more effective to convert oxygenated compounds to hydrocarbons due to the integrated cracking and hydrodeoxygenation reactions. Compared to HZSM-5, 6%Ni/HZSM-5 catalyst produced the bio-crude product with the highest hydrocarbon content at 11.02%. HZSM-5 produced the highest bio-crude yield at 64.31 wt.%.(Download PDF) (Export to EndNotes)
