Abstract

The invention provides a method for preparing methanoic acid by the catalytic hydrogenation of a nanometer porous nickel material. The method comprises the following steps: after a carbon source, solvent and the nanometer porous nickel material are mixed, regulating a pH value to 8-12, reacting at a temperature of 150-200DEG C under hydrogen atmosphere, carrying out solid-liquid separation after reaction is finished, and collecting a liquid part to obtain methanoic acid solution or formate solution. Compared with the prior art, the method has the following beneficial effects: the method for preparing the methanoic acid by the catalytic hydrogenation of CO2 and carbonate by the nanometer porous nickel material has the advantage of abundant raw material resources (such as industrial exhaust gas, automobile exhaust and the like) and is nontoxic or harmless, fossil energy does not need to be consumed, and CO2 emission can be effectively reduced. Water is used as reaction solvent so as to be environmental-friendly and pollution-free. The nanometer porous nickel material which is cheap and can be easily prepared is used, the highest yield of the methanoic acid can be 92.1%, and selectivity is good.

Description

technical field [0001] The invention relates to a method for preparing formic acid by catalytic hydrogenation of a nanoporous nickel material, which belongs to the technical field of energy and chemical industry. Background technique [0002] As the main greenhouse gas, CO 2 The amount of emissions is increasing year by year, which has caused a series of adverse effects on the environment and ecology, such as temperature rise, glacier melting, forest degradation, sea level rise, etc. On the other hand, the massive consumption of fossil fuels has led to a crisis of energy shortage and an imbalance in the global carbon cycle. CO 2 As a recyclable C1 resource, it is rich in content, cheap and easy to obtain, and non-toxic and harmless. Therefore, how to efficiently use CO 2 The production of chemical products with high added value is a research hotspot of scholars. CO 2 The utilization of resources can not only effectively reduce the CO in the atmosphere 2 concentration,...
