TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Process: The biomethanol is recovered from black liquor by distillation and/or stripping. The crude biomethanol recovered from black liquor is purified and reformed, after recovering biohydrogen. The purification process is carried out by washing, scrubbing, stripping, liquid-liquid separation, distillation, catalytic conversion, ion exchange, absorption or adsorption. The reforming process is carried out by autothermal reforming or steam reforming. The biohydrogen is recovered by separating biohydrogen from carbon dioxide in a pressure swing adsorption unit. The crude biomethanol recovered from black liquor is purified and reformed to obtain biohydrogen, and purified biohydrogen is recovered. A biohydrocarbon stream is produced by Fischer-Tropsch reaction of syngas produced from biomass and/or hydrodeoxygenation of biological triglycerides or fatty acids. The recovered purified biohydrogen and the biohydrocarbon stream are separated into fractions and biofuel is recovered from the fractions. The biomethanol is reformed together with gaseous stream which emanates from biofuel production process and contains gaseous component of forming hydrogen by reforming. Preferred Composition: The biomass contains biological waste or by-products of wood processing industry and Kraft pulp mill. The triglyceride or fatty acid contains tall oil or tall oil fatty acids. The biofuel contains biohydrocarbon produced from biological waste and/or byproducts of Kraft pulp mill and biohydrogen produced from black liquor. Preferred Component: The recovery unit has a stripping unit and/or distillation unit. The methanol purification unit has a scrubbing unit, a washing unit, a stripping unit, an adsorbing unit, an absorbing unit and/or catalytic reactor unit. The reforming unit has an autothermal reforming unit (7) or steam reforming unit. The hydrogen purification unit has an adsorbing unit.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The biomethanol contains purified biomethanol derived from black liquor.
