SYNTHETIC GAS PRODUCTION METHOD Russian patent published in 2018 - IPC C10J3/00 C10G15/08 

FIELD: technological processes.

SUBSTANCE: invention relates to a method for producing synthesis gas by thermochemical processing of a combined feedstock consisting of plant material and a heavy hydrocarbon feedstock. Process is carried out by heating the heavy hydrocarbon feedstock to a temperature of 60–90 °C, and the vegetable raw material is subjected to grinding to a degree of grinding of at least 100 mcm. Thereafter, said heavy hydrocarbon feedstock and plant raw materials are mixed, followed by dispersing the resulting mixture in the presence of water and carbon black to form a slurry, which is subjected to successive acoustic treatment with a frequency of 21–25 kHz, an emission intensity of 5–10 W/cm² at a temperature of 50–70 °C and processing time of 1–3 hours and electromagnetic processing with a radiation frequency of 40–60 MHz, capacity of 0.2–0.6 kW at a temperature of 50–70 °C, treatment time 1.0–8.0 hours. Gasification of the treated suspension is then carried out at a temperature of 800–1,200 °C to produce a synthesis gas that is purified with the separation of the carbon black used in the dispersing step.

EFFECT: technical result consists in increasing the ratio H₂:CO in synthesis gas with simultaneous reduction of soot formation.
