Abstract

The invention provides a system and method for producing fuel chemicals by conducting solar high-temperature thermal-coupling on methane. The method includes the steps of introducing CO2-enriched gasinto a first high-temperature thermochemical reactor, carrying out a thermochemical decomposition reaction to produce a gas mixture of CO and CO2 and first oxygen under irradiation of first sunlight,and making the gas mixture of CO and CO2 sequentially pass a first temperature reducing device and a CO2 removal device to become CO-enriched gas; introducing water vapor into a second high-temperature thermochemical reactor, carrying out a thermochemical decomposition reaction to produce a gas mixture of water vapor and H2 and second oxygen under irradiation of second sunlight, and making the gasmixture of water vapor and H2 sequentially pass a second temperature reducing device and a dewatering device to become H2-enriched gas; after mixing methane-enriched gas with the first oxygen and thesecond oxygen, carrying out a reaction in a methane partial-oxidation reactor to produce synthesis gas; mixing the synthesis gas, the CO-enriched gas and the H2-enriched gas to be introduced into a fuel chemical synthesis tower for reacting to obtain the fuel chemicals.

Description

technical field [0001] The invention relates to the technical fields of solar energy application and coal chemical industry, in particular to a zero-carbon emission system and method for producing fuel chemicals by utilizing solar high-temperature thermal coupling methane. Background technique [0002] In the face of increasingly serious energy crisis, environmental pollution and other issues, while adhering to the road of sustainable development, the resource-rich solar energy is very valuable as a new type of clean energy. It is estimated that the amount of sunlight shining on the earth is huge, and the synthesis of all the fossil energy stored on the earth is only equivalent to the sunlight shining on the earth for 18 days. The sunlight that hits the earth every hour is enough to meet the entire energy demand of the world for a year. At the same time, the sun is the ultimate source of almost all kinds of energy on the earth, directly or indirectly. Fossil fuels -- coal,...
