SYNTHETIC GAS PRODUCTION METHOD Russian patent published in 2019 - IPC C10J3/00 C10B53/02 C10G15/08 

FIELD: technological processes.

SUBSTANCE: invention relates to production of synthesis gas by thermochemical treatment of vegetal raw materials and heavy hydrocarbon material. Method includes heating of heavy hydrocarbon material to 60–90 °C, milling vegetal raw material to particle size of not more than 200 mcm, pyrolysis of milled vegetal raw material at 500–800 °C to produce first gas stream, resin and semi-coke, mixing resin and semi-coke with heavy hydrocarbon feedstock. Method then includes dispersing said mixture in the presence of an aqueous suspension of soot and water to obtain a suspension which is successively subjected to acoustic treatment with a radiation frequency of 21–25 kHz, radiation intensity of 5–10 W/cm², treatment time 1.0–3.0 h and electromagnetic processing with radiation frequency of 40–60 MHz, power of 0.2–0.6 kW, processing time of 1.0–8.0 hours at temperature of 50–70 °C to form a treated suspension, which is fed for gasification at 800–1,400 °C to produce a second gas stream, separating the aqueous soot suspension from the second gas stream. Then, the first gas flow and the second gas flow are mixed after separating the aqueous suspension of soot and the formed mixture is purified to obtain the target synthetic gas.

EFFECT: technical result is higher ratio H₂:CO in synthesis gas with simultaneous reduction of soot formation.
