A syngas generator is disclosed as an exothermic gas generator that can accommodate high combustion temperatures of a natural gas/oxygen flame. The generator consists of four sections: a heavily insulated combustion chamber, a catalyst chamber, a spray chamber, and a heat exchanger. These four sections may be arranged in series and tightly bolted together to form a gas-tight system. Natural gas, oxygen and steam are supplied to a burner at the inlet end of the combustion chamber. This mixture is ignited and the resulting hot process gas is then fed into a catalyst bed where it reacts with the steam and is converted to carbon monoxide and hydrogen (syngas). The syngas is fed to a Fischer-Tropsch unit to create liquid fuel.

A method for preparing hydrogen-rich synthesis gas by degrading waste polyolefin plastics at a low temperature includes the following steps: weighing 1 part by weight of polyolefin waste plastics and 3 parts-80 parts by weight of hydrogen peroxide containing 0.25%-6% of H.sub.2O.sub.2; feeding the polyolefin waste plastics and the hydrogen peroxide into a hydrothermal reactor, and carrying out the oxidation pretreatment reaction at a reaction temperature of 150° C.-230° C. under a reaction pressure of 0.5 MPa-2 MPa for 30 minutes-90 minutes, and obtaining an aqueous-phase product and a gas-phase product after the reaction is finished; filling another hydrothermal reactor with a mesoporous carbon supported metal-based catalyst, and then introducing the aqueous-phase product into the hydrothermal reactor for a reforming reaction to obtain a hydrogen-rich synthesis gas product.
