Abstract

The invention belongs to the technical field of oxidation catalyst preparation, and particularly relates to a preparation process of a special oxidation catalyst for acrylonitrile volatile matters. The process comprises the following process steps: S1, preparing carrier raw materials including the following raw materials in parts by weight: 2-5 parts of rhodium chloride, 45-55 parts of ceramic powder, 25-35 parts of ammonium heptamolybdate, 10-15 parts of titanium dioxide sol and 40-45 parts of polyvinyl alcohol; S5, coating: coating a mixture C with the titanium dioxide sol; S6, roasting: putting the mixture C into a calcining furnace, heating to 1200 DEG C at a heating speed of 100 DEG C / h, and performing calcining for 3 hours at 1200 DEG C to obtain the special oxidation catalyst for the acrylonitrile volatile matters; and S7, packaging: packaging the obtained oxidation catalyst in a packaging machine. By using a mixer, the mixing efficiency of a mixture can be improved, the uniformity of the mixture is improved, and the mixer is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of preparation of oxidation catalysts, in particular to a preparation process of a special oxidation catalyst for acrylonitrile volatiles. Background technique [0002] Due to the characteristics of water (such as non-toxic, cheap, wide sources, etc.), it is often used as a reaction solvent, medium or heat carrier in the chemical production process, so the water quality of the water body is inevitably damaged. With the vigorous development of the chemical industry, water pollution is increasing year by year, and the pollution of toxic organic substances to water is particularly serious. This kind of pollutant has the characteristics of large discharge, wide pollution area and refractory biodegradation, which has seriously threatened human life and restricted the development of chemical industry. Therefore, research on how to treat industrial organic wastewater with high efficiency and energy saving has beco...
