Catalytic pyrolysis using catalyst nickel-natural zeolite (Ni/NZA) on conversion of biomass to bio-oil

Abstract

World crude oil demands tend increase while it supplies decreases. Due to limit of fossil fuel resources on future, hence finding out renewable resource is inevitable. Bio-oil is one of an alternative energy source produced by pyrolysis of biomass. Pyrolysis is a potentially important route for biomass conversion to fuel by heating of biomass in the absence of oxygen to produce bio-oil. Trunk, shell and fiber of palm oil solid wastes were used as sample. The Catalytic Pyrolysis process were conducted in pyrolysis reactor using biomass of 50 gram, silinap 500 ml and Ni/NZA catalyst of 1.5 gr at 320°C. In this research the effect of ratio of nickel metal in catalyst of 1, 3 and 5 wt/wt % respectively in activated natural zeolite (NZA) were investigated. The maximum bio-oil result of 63.0 % is obtained from trunk having the particle size of -8+10 mesh with the catalyst of Ni 3%. Bio oil result is analysed which includes acidity, density, viscosity and flash poit. And bio oil chemical components were characterized using GC-MS.
