FIELD: process engineering.
SUBSTANCE: invention relates to hydrothermal treatment of biomass. Proposed method comprises the feed of biomass-based stock to reaction area. Stock water-to-biomass ratio makes at least 1:1. Note here that biomass-based stock contains phosphorus while stock hydrothermal processing is conducted under conditions efficient for hydrothermal processing with yield of multiphase product. The latter includes a fraction of solid particles containing about 80% of phosphorus of its content in said stock. Molar ratio between phosphorus and carbon of said fraction of solid substances makes at least 0.2. Said multiphase product is separated to get at least one gas-phase fraction, liquid hydrocarbon product and fraction of solid substances. Invention claims also the versions of process implementation.
EFFECT: efficient process, production of liquid hydrocarbon product.
