Abstract

Bio-oil, a liquid product from biomass via fast pyrolysis, by the virtue of its environmentally friendly potential, is regarded as a promising energy source. In spite of that, it has certain limitations that bring on many problems in its handling and utilization. Thus, bio-oils require upgrading to improve their characteristics before they can be used as replacement for fuels. The objective of this project is to upgrade bio-oil over different solid catalysts. Based on the literature review, it is concluded that esterification is the most preferable upgrading technique due to the properties of bio-oil resulted from the process and its low production cost. To carry out the esterification either a homogenous or heterogeneous catalyst can be used. For this project, heterogeneous catalyst is used whereas the scope is within the usage of solid acid and solid base catalysts, specifically 40SiO2/TiO2-SO42" and 30K2CO3/Al2O3-NaOH. The research methodology of this project consists of artificial bio-oil preparation, catalysts preparation, esterification experiment and characterization of bio-oil. The results and discussion analysis along with case study to compare with previous similar project are conducted. At the end, both solid acid and solid base catalysts successfully converted the bio-oil into esters through esterfication experiment. For generating solid acid catalyst, new approach is used: by using silica gel and highly dispersed Si02 as the materials. It is also concluded that this project gives a fast reaction rate in achieving the equilibrium conversions and that the characteristics of upgraded bio-oil in this project are improved to standard biodiesel properties.
