Abstract: The present disclosure provides a method for catalytic conversion of waste plastic into liquid fuel. The method comprises thermally decomposing the waste plastic at a temperature in the range of 350 to 650° C. and under a pressure in the range of 0.0010 psi to 0.030 psi, to obtain a gaseous stream. The gaseous stream is further subjected to four stage sequential cooling to a temperature in the range of −5 to −15° c. to obtain a gas-liquid mixture comprising a gaseous fraction and a liquid fraction. The gas-liquid mixture is fed to the gas-liquid separator to obtain the gaseous fraction comprising C1 to C4 hydrocarbons and the liquid fraction comprising liquid fuel. The method of the present disclosure is simple, economical and energy efficient, which provides a high value liquid fuel with enhanced yield.

Abstract: The invention discloses a method for producing bio-fuel (BF) from a high-viscosity biomass using thermo-chemical conversion of the biomass in a production line (10) with pumping means (PM), heating means (HM) and cooling means (CM). The method has the steps of 1) operating the pumping means, the heating means and the cooling means so that the production line is under supercritical fluid conditions (SCF) to induce biomass conversion in a conversion zone (CZ) within the production line, and 2) operating the pumping means so that at least part of the production line is in an oscillatory flow (OF) mode. The invention is advantageous for providing an improved method for producing biofuel from a high-viscosity biomass. This is performed by an advantageous combination of two operating modes: supercritical fluid (SCF) conditions and oscillatory flow (OF).

Abstract: A pyrolysis reactor (12) and method for the pyrolysis of hydrocarbon gases (e.g., methane) utilizes a pyrolysis reactor (12) having a unique burner assembly (44) and pyrolysis feed assembly (56) that creates an inwardly spiraling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a burner conduit (46) with a constricted neck portion or nozzle (52). At least a portion of the swirling gas mixture forms a thin, annular mixed gas flow layer immediately adjacent to the burner conduit (46). A portion of the swirling gas mixture is combusted as the swirling gas mixture passes through the burner conduit (46) and a portion of combustion products circulates in the burner assembly (44). This provides conditions suitable for pyrolysis of hydrocarbons or light alkane gas, such as methane or natural gas.
