Abstract

The combustion catalyst for carbon-base fuel is prepared through compounding the main material and the auxiliary material into matrix, and dissolving the matrix in solvent. The main material includes alkyl alcohol ether, alkyl ester, olefin and aromatic compound; and the auxiliary material includes phosphate ester, chlorohydrocarbon, alkyl alcohol amide, metal compound and small amount of nitrogen, silicon and oxygen containing organic compound. When it is used, the combustion catalyst is mixed with carbon-base fuel through spraying or stirring. It promotes combustion by means of increasing the free radicals in the system, and can raise the combustion strength and efficiency and reach the aims of saving energy, raising efficiency, reducing pollution, etc.

Description

technical field [0001] The invention belongs to the technical field of catalytic combustion of carbon-based fuels. Background technique [0002] Energy is an indispensable material basis for economic development and social life. my country's primary energy is dominated by carbon-based fuels (including coal, coke, charcoal, biomass, asphalt, residual oil, heavy oil, etc.), and it is predicted that from 2000 to 2010, the proportion of coal alone in my country's primary energy demand will be 70%. %, and can be reduced to less than 50% in 2050, but the absolute amount of coal consumption is still greatly increased. According to statistics, in the total amount of carbon-based fuels consumed in my country, more than 85% of the carbon-based fuels directly used for thermal power generation, industrial boilers, industrial kilns and household stoves are directly burned. [0003] The large amount of direct combustion of carbon-based fuels, coupled with the poor quality and low combust...
