Embodiment

[0099] · Invention Example 1

[0100] After removing impurities such as hydrogen chloride, a branch pipe is installed on the exhaust gas (hereinafter referred to as Purified synthesis gas) generated by the thermoselect waste gasification and reforming process (Thermoselect WasteGasification and Reforming Process), through which the exhaust gas can be discharged. Partial heat. On the downstream side of the branch pipe, a flow control valve, a steam mixer, a gas preheater, a reforming reactor (external heating type rotary furnace), and a gas cooling system for cooling the reforming reaction product gas equipped with a liquid fuel trap are arranged in sequence. device. A quantitative feeding device for waste plastics in the form of a screw feeder is arranged on the feeding side of the reforming reactor. In addition, a sampling port and a flow meter are installed on the discharge side piping of the cooled gas of the gas cooler.

[0101] The average composition of the hot gas is...

Abstract

An organic substance is reformed and lowered in molecular weight by: producing a mixed gas (g) by mixing water vapor to a gasification melting furnace-generated exhaust gas (g0) that contains carbon dioxide and hydrogen; or adding an excessive amount of water vapor to a gasification melting furnace-generated exhaust gas (g1) that contains carbon monoxide and hydrogen to cause a shift reaction, and thereby producing a mixed gas (g) that contains the hydrogen contained in the exhaust gas (g1), carbon dioxide and hydrogen produced by the shift reaction, and the water vapor that was not consumed by the shift reaction; and bringing said mixed gas (g) into contact with said organic substance.

Description

technical field [0001] The present invention relates to a method for modifying organic substances to make them low molecular weight, which is used for converting waste plastics and other organic substances into gaseous fuels, liquid fuels and the like. Background technique [0002] At present, waste plastics, oily sludge, waste oil, etc. are mostly incinerated. However, CO is produced during incineration 2 However, the burden on the environment is high, and there is also the problem of thermal damage to the incinerator, so it is necessary to establish a chemical recycling technology. [0003] Among the chemical recycling technologies, various researches have been conducted centering on waste plastics as technologies for converting organic substances into gaseous fuels or liquid fuels, and the following proposals have been proposed, for example. [0004] Patent Document 1 discloses a method for efficiently hydrocracking organic substances by reacting coke oven gas (COG) hav...
