carbonaceous feed pyrolysis apparatus and bio-oil production process

摘要

carbonaceous feed pyrolysis apparatus, and bio-oil production process. The invention provides a carbonaceous pyrolysis apparatus comprising two or more hot particle fluidized beds, and one or more positive displacement apparatus for the transfer of hot particles between two or more of the beds, wherein one or more of the fluidized beds contains / contain a combustion zone. The invention includes a process for producing bio-oil, including pyrolysis of a carbonaceous biomass, which process includes 2 or more fluidized beds, a first combustion zone carried out in one or more fluidized combustion beds in which a particulate material is fluidized and and a second pyrolysis zone carried out in one or more pyrolysis fluidized beds in which hot particles heated in the combustion zone are used for biomass pyrolysis, said combustion zone being operated at or about atmospheric pressure at a temperature 400 198 ca 1,100 198 c, typically around 900 198 c, and the pyrolysis zone being operated at a pressure from atmospheric pressure to 10,000 kpa (nanometer) at a temperature of 400 198 ca 900 198 c.
