Abstract
A rapid thermal conversion process for efficiently converting wood, other biomass materials, and other carbonaceous feedstock (including hydrocarbons) into high yields of valuable liquid product, e.g., bio-oil, on a large scale production. Biomass material, e.g., wood, is feed to a conversion system where the biomass material is mixed with an upward stream of hot heat carriers, e.g., sand, that thermally convert the biomass into a hot vapor stream. The hot vapor stream is rapidly quenched with quench media in one or more condensing chambers located downstream of the conversion system. The rapid quenching condenses the vapor stream into liquid product, which is collected from the condensing chambers as a valuable liquid product. The liquid product may itself be used as the quench media.
Claims14
A method for converting biomass or non-biomass feedstock into liquid product comprising:
- mixing feedstock with solid heat carriers in a reactor to thermally convert the feedstock into a vapor stream at a conversion temperature of between 350 and 600° C.;
- separating the solid heat carriers from the vapor stream;
- rapidly quenching the vapor stream with a quench media to a temperature of less than 100° C. in less than 1 second in a condensing chamber to condense the vapor stream into liquid product;
- and
- collecting liquid product from the condensing chamber.
