Catalytic hydrothermal liquefaction of empty fruit bunch(EFB)with no added H2 effectively produces biomass derived fuel or known as bio-oil.In this study,a bimetallic modified zeolite(BaNi,BaLa and BaCe/CHZSM5)catalyst with a series of dosage ratio(1:1,1:2 and 2:1)was used for the EFB conversion to bio-oil.Ni,La and Ce addition to the Ba/CHZSM5 showed significant changes on the physicochemical properties of catalysts and exhibited enhanced catalytic performance.The activity-structure correlation revealed that EFB conversion and bio-oil yield were favoured on bimetallic modified CHZSM5 and the most effective catalyst was BalLa2/CHZSM5.Brunauer-Emmett-Teller(BET)surface area measurement and temperature programmed desorption of ammonia(TPD-NH3)results confirmed that high surface area and rich acidic sites of BalLa2/CHZSM5 catalyst eventually enhanced the catalytic activity in HTL of EFB.Comparing to other bimetallic modified catalyst,the desirable aromatic and aliphatic hydrocarbon also predominated over BalLa2/CHZSM5 catalysed reaction which demonstrated that this catalyst have a good ability in produce high quality of bio-oil with less oxygenated compounds.
