Abstract

The invention discloses a method for intensifying a carbon dioxide catalytic hydrogenation reaction. The method for intensifying the carbon dioxide catalytic hydrogenation reaction mainly comprises the following steps that active ingredients having capacity for catalyzing CO2 hydrogenation are loaded on a porous conductive framework to prepare a structural catalyst; the structural catalyst is plugged into a circuit to conduct a current; and the structural catalyst is placed in raw material gas containing CO2 and hydrogen, a power source is turned on to apply the current on the circuit, joule heat generated on the structural catalyst of the current can heat the structural catalyst to a temperature at which CO2 hydrogenation reaction can be carried out, and CO2 and hydrogen react on the structural catalyst. The current is applied on the structural catalyst of the conductive framework to realize electric internal heating, so that the catalyst is heated more uniformly, activity and sulfurpoisoning capacity of the catalyst are improved, and the conversion performance of CO2 is obviously improved.

Description

technical field

[0001] The invention relates to the field of gas-solid heterogeneous catalysis, in particular to a method for strengthening the catalytic hydrogenation reaction of carbon dioxide. Background technique

[0002] The excessive development and use of traditional fossil energy has resulted in carbon dioxide (CO 2 ) has caused serious environmental and ecological problems. to CO 2 Recycling and resource utilization are powerful means to reduce emissions. Hydrogen produced by splitting water with electricity can convert CO 2 Converted into useful fuels and chemicals (methane, methanol, etc.), CO 2 Emission control provides an effective technical solution for mitigating the greenhouse effect and large-scale storage of hydrogen energy.

[0003] CO 2 The molecule is one of the most chemically stable molecules, and its hydrogenation reaction needs to overcome a high reaction energy barrier. Generally, the conversion with low energy consumption is achieved by lowe...
