摘　　要：Microbial, vegetal or animal organic matter, which has potential to be transformed into energy, is considered biomass. Among the various alternative energy sources, biomass is the only one with the possibility of generating a class of substances of interest for fine chemistry （ketones, aldehydes, alcohols, phenols, etc.）. From biomass, it is possible to produce bio-oil using pyrolysis, a thermodegradation process. The quality of the bio-oil depends on the process conditions （pyrolysis temperature, heating temperature, etc.） and biomass used. In this paper, the pyrolysis （using a fixed bed reactor） of three biomasses （coconut fiber, coffee grounds and sugar cane straw） is studied. The results indicated that the bio-oil yields for all biomass were similar, approximately 37%. The chemical profile obtained by gas chromatography coupled with mass spectrometry （GC/qMS） showed high amounts of fatty acids in the coffee grounds bio-oil and aliphatic and aromatic hydrocarbons in coconut fiber bio-oil, whereas guaiacols were the predominant components of the sugar cane straw bio-oil.
