Abstract

Disclosed is a highly effective environmental protection catalysts coal-saving agent, which comprises 20-30 weight parts of puffing agent composing of mixture of lignin sulfonate and alkylbenzene sulfonate, 30-40 weight parts of emulsifying agent composing alkylphenol polyoxyethylene, 8-15 weight parts of purifying agent composing polyethylene oxide, 15-25 weight parts of catalyst composing the mixture of palladium metal salts, titanium metal salts and cerium metal salts, 3-10 weight parts of catalyst promoter composing cobalt metal salts, 3-10 weight parts of modifier composing alkaline metal and/or alkaline metal hydrates. The invention also discloses the process for preparing the coal-saving agent and its use.

Description

technical field [0001] The invention relates to a solid fuel, especially a catalytic combustion aid for coal, that is, a high-efficiency environmental protection catalytic coal-saving agent and its preparation method and application. A coal-saving agent composed of a regulator belongs to the technical field of coal catalytic combustion. Background technique [0002] Energy is the driving force behind economic development. The energy used by countries all over the world is mainly primary energy, which accounts for more than 93% of the total energy consumption. The primary energy consumption is mainly oil, coal, and natural gas, which are the three basic energy sources in the world. Coal is the fossil fuel with the most abundant reserves in the world. Coal is not only a power fuel, but also a raw material for chemical industry and coking and iron making. It is known as "industrial food". At present, the economically recoverable reserves of coal are about 984.5 billion tons,...
