Abstract

See full text

Apparatus and process for producing hydrocarbons from biomass having a pyrolysis reactor (2) in which dry biomass (Bd) is heated in an environment substantially free from oxygen and halogens, a pyrolysis product (PP) and char (C) is produced, a gasification reactor (3) in which separated char (C) is heated in an environment containing steam (Wst) to reduce the char (C) to produce a synthesis gas (Sh), a gas cooler (4) in which the produced synthesis gas (Sh) is cooled to a cooled synthesis gas (Srt); a conditioning and pressure system (5) in which cooled synthesis gas (Srt) is refined to produce a purified synthesis gas (Sp), and a separation device (6) in which hydrogen gas (H2) is separated from purified synthesis gas (Sp). A hydrogenation device (7) into which pyrolysis oil (PO) retrieved from the pyrolysis product (PP) and separated hydrogen gas (H2) recuperated from the separation device (6) are introduced for hydrogenation in which pyrolysis oil (PO) is hydrogenated by the presence of hydrogen gas (H2), and hydrocarbons (BO) that are substantially free from oxygen are produced.
