Embodiment 1～3

[0115] waste oil at a rate of 10 kg / h in figure 2gasification in the gasification reactor shown in . The diameter of the reactor was 250 mm and the total length was 2000 mm, including the upper and lower end sections. At the lower end of the reactor, gas supply nozzles and oxygen supply nozzles respectively connected to the generated gas recirculation pipe and the oxygen supplier are installed on the wall along the tangential direction. At the lowermost end of the reactor, a burner for preheating the reactor to about 600° C. in the early stage of the reaction was installed. After preheating the reactor to 600° C., the burner was removed to equip an ash trap for trapping the ash remaining after the gasification reaction. In addition, an observation port for observing the state of the reaction carried out in the reactor and equipment for determining the temperature and pressure in the reactor were installed in the flange plate on the wall of the reactor.

Abstract

A method of gasifying organic materials (carbonaceous compounds) such as coal, shredded waste tire or waste oil into gaseous fuel, carbon monoxide and hydrogen, and an apparatus therefore are provided. The method comprises the steps of supplying initial fuel gas and oxygen into a gasification reactor to produce water and carbon dioxide, supplying the organic materials into the reactor and reacting them with the water and carbon dioxide to produce carbon monoxide and hydrogen gas, discharging the carbon monoxide and hydrogen gas from the reactor, recycling a part of the carbon monoxide and hydrogen gas discharged from the reactor into the reactor, and reacting the carbon monoxide and hydrogen gas supplied into the reactor with oxygen to produce water and carbon dioxide. The method facilitates the control of temperature in the gasification reactor as well as produces fuel gas of high quality by increasing the concentration of hydrogen.

Description

technical field [0001] The present invention relates to a method for gasifying large molecular weight organic materials (carbonaceous materials) such as coal, waste oil, crushed tires, garbage or waste into gaseous fuel, carbon monoxide and hydrogen, and also relates to a device used in the method. Background technique [0002] The gasification of carbonaceous liquid wastes such as waste oil or waste organic solvents and solid carbonaceous materials such as coal or pulverized waste tires refers to the conversion of carbon and hydrogen contained in organic materials into fuel gas, carbon monoxide and hydrogen (commonly known as synthetic gas). Because gasification is an endothermic reaction requiring continuous heat supply, the gasifier should be maintained at a high enough temperature for the reaction to continue. [0003] In a conventional method of gasification, a gasification furnace is maintained at a high temperature by combustion heat generated from an oxidation react...
