Abstract

Wood and sugar-eane usage in Brazil is outlined from the perspective of the opportunities for conversion into liquid fuels using modern pyrolysis techniques and conversion technologies.

Wood consumption in Brazil exceeded 130million tons in 1986, with about 40% being converted to charcoal for steel production. Wood carbonization is carried out in brick kilns, and major manufacturers also have condensation units for tar recovery. Liquid by-products are used as boiler fuels and also, after further processing, as a source of chemicals such as methanol and acetic acid.

In 1986 also, cane consumption reached over 200 million tons for production of ethanol and sugar. The by-products of these processes include bagasse which is used for steam raising, to substitute for fuel oil in agro-industry and as cattle feed after appropriate defibrelation treatment. Sugar-eane bagasse may also be used as an interesting source offuels and chemicals, by ultrafast pyrolysis of biomass. A new project has been established to exploit this technology.
