Description

[0001] Involved areas [0002] The invention relates to a sulfonic acid functional nano-carbon intercalation clay catalytic material and a preparation method thereof, belonging to the field of material preparation and application. Background technique [0003] Liquid acid is an important acid catalyst in the chemical production process, and millions of tons of industrial concentrated sulfuric acid are used in petrochemical production every year. However, the catalyst separation in the concentrated sulfuric acid catalytic system is a complex and risky project. A large amount of waste acid is produced every year, which is not only a waste, but also brings great pressure on environmental protection. In recent years, with the improvement of environmental protection requirements in industrial production, there is an urgent need to develop solid acid catalysts that can replace liquid acids, have strong acid catalytic activity, and can be reused. An ideal solid acid catalyst needs ...
