Catalytic reburning of waste gas on platinum glass-fiber catalysts IC-12-S102

Abstract

The process of catalytic afterburning of volatile organic compounds (VOCs) in industrial waste gases on new platinum fiberglass catalyst IC-12-S102 with a low platinum content (0,02 % wt.) is developed. This catalyst is superior to well-known in domestic and world practice of industrial catalytic afterburner. The way of glass fiber catalyst loading to a reactor in the form of vertical spiral cartridges, structured wire mesh weaving volume is described. The successful application of catalyst IC-12-S102 confirmed by its operation at «Nizhnekamskneftekhim» in the process of waste gases afterburning in industrial reactor with cleaned gases capacity up to 15 000 m3/h. During the reactor operation in harsh conditions (low oxygen content, high content of water vapor) the degree of gas cleaning was 99,5–99,9 %, and the residual VOC content in the purified gases was not more 10–15 mg/m3. For more than 15 months of the catalyst operation, the degree of gases purification was not reduced, thus overall lifetime of the catalyst IC-12-S102 may be substantially longer than the life of well-known industrial afterburning catalysts.
