Abstract

The invention discloses a production process of a metal oxide supported boron-silicon-containing phenolic resin-based active carbon tail gas desulfurizer for producing hydrogen fluoride. The production process comprises the following steps: firstly introducing boron and silicon atoms into a phenolic resin framework for effectively improving the heat resistance and oxidation resistance of the phenolic resin, then carrying out carbonization to obtain boron-silicon-containing phenolic resin carbon, and then activating the boron-silicon-containing phenolic resin carbon to finally obtain the metaloxide supported boron-silicon-containing phenolic resin-based active carbon tail gas desulfurizer. The production process provided by the invention has the following beneficial effects that (1) the desulfurization efficiency is high; (2) the number of holes in the desulfurizer is large; and (3) the desulfurizer can be recycled and reused.

Description

technical field [0001] The invention relates to a production process of a desulfurizing agent, in particular to a production process of a metal oxide-loaded borosilicate phenolic resin-based activated carbon tail gas desulfurizing agent used for hydrogen fluoride production. Background technique [0002] There are many types of odorous pollutants produced in the hydrogen fluoride production process, such as sulfides, nitrides, fluorides, and various organic solvents. At present, China's emission standard for odor pollutants (GB14554-93) defines 8 types of odorous substances, five of which are sulfur-containing compounds, so sulfur-containing compounds are the main target pollutants for odor control. Sulfur-containing compounds are toxic and corrosive substances, which not only cause direct harm to personal safety, but also cause corrosion of devices, equipment and pipelines, and poison and deactivate catalysts, which in turn leads to increased processing costs and affects th...
