Abstract
Thermal pyrolysis of biomass produces a bio-oil of low quality, thereby it was proposed the use of a catalyst in order to improve the quality and yield of products. Several studies have highlighted the use of catalysts to improve bio-oil quality. There are many types of catalyst, alkaline catalysts such as metallic oxide have demonstrated a deoxygenating capacity. In literature, there are many studies about catalytic pyrolysis in-situ because of their simplicity and low cost, however, there are few studies about ex-situ catalytic pyrolysis. In this type of pyrolysis, the catalyst is separated from biomass. In Brazil, sugarcane is an important energy crop used for ethanol production, thereby, large quantities of sugarcane bagasse are generated. Nowadays there are many alternatives for using this resource, one of them is pyrolysis. In literature, the are scarce studies about ex-situ catalytic pyrolysis of sugarcane bagasse, moreover, the possibility of obtaining bio-oil has not yet been studied. Thus, the objective of this work is to study the ex-situ catalytic pyrolysis of sugarcane bagasse for bio-oil production. The preliminary results show that bio-oil has more higher heating value. The temperature of the catalytic reactor has influenced on properties of bio-oil. Calcium oxide has the potential to be used as a catalyst in ex-situ catalytic pyrolysis.
