Abstract

The invention provides a nickel-containing catalyst. The nickel-containing catalyst contains a magnetic carrier and nickel which accounts for 5-30 weight percent of the nickel-containing catalyst and is loaded on the magnetic carrier. The invention further provides a method for removing H2 in a CO raw material. The method comprises the following steps: making the CO raw material be contact with the nickel-containing catalyst under the condition of a methanation reaction, wherein the nickel-containing catalyst is the nickel-containing catalyst provided by the invention. The method for removing H2 in the CO raw material, provided by the invention, can be used for rapidly reducing the content of H2 in the CO raw material to below 310ppm by adopting the nickel-containing catalyst without adopting a precious metal catalyst or adding oxygen in the reaction.

Description

technical field [0001] The invention relates to a nickel-containing catalyst, and the use of the nickel-containing catalyst to remove H in CO raw materials 2 Methods. Background technique [0002] The technology of using coal or natural gas instead of petroleum ethylene to synthesize ethylene glycol through oxalate is recognized as the most scientific raw material route, the most reasonable resource utilization, and obviously superior to the petroleum route. According to calculations, if the world’s 22 million tons of ethylene glycol produced from petroleum ethylene are produced with this technology, it is equivalent to the successful development of a new Daqing Oilfield with an annual output of 55 million tons of oil above the scale, and its output value is nearly 200 billion yuan. . Combined with my country's current situation of lack of oil, gas, and relatively rich coal resources, the development of technology for preparing ethylene glycol from coal has significant eco...
