Preparation method of nickel-supported halloysite-based methane dry reforming catalyst

Abstract

The invention relates to a method for preparing a nickel-loaded halloysite-based methane dry reforming catalyst. The preparation method comprises the following steps: performing in situ modification on the surface of halloysite used as a carrier by a molten salt ball-milling technology to disperse and anchor an active nickel species, loading a nickel precursor on the modified surface of halloysiteby a rotary evaporative impregnation technology in order to realize uniform dispersion and strong interaction of all metals, and performing drying, high-temperature calcination and temperature programming reduction to finally obtain the catalyst with high resistance to sintering and carbon deposition. The catalyst has the advantages of simple preparation process, low cost, no pollution to the environment, high catalytic efficiency and the like.

Description

technical field

[0001] The invention relates to a preparation method of a nickel-loaded halloysite-based methane dry reforming catalyst, belonging to the technical fields of nano-catalyst preparation technology and environmental protection. Background technique

[0002] With the consumption of coal and petroleum fuels, fossil energy is increasingly scarce, and the problem of environmental pollution caused by its combustion continues to aggravate. With the rapid development of society, the world's energy structure is constantly changing, and natural gas as a clean energy has received extensive attention. The main component of natural gas is methane. According to scientific research, China's demand for natural gas will increase in the next few years, and natural gas will play an important role in the energy structure. The effective use of natural gas can not only reduce carbon dioxide emissions, but also It is beneficial to alleviate the impact of the greenhouse effect on hum...
