The using of APKGS-20SH catalyst for the removal of air emissions in the rubber production on «Voronezhsintezkauchuk»

Abstract

In this paper, the authors presented the results of pilot tests of «crusted» 0,2%Pd/γ-Al2O3-catalyst APKGS-20SH at «Voronezhsintezkauchuk» for air emissions cleaning, as well the results of industrial exploitation. Stable operation (degree of purification of ventilation emissions) of the catalyst was observed under real operating conditions that differ significantly from the regulatory norms for the input concentration and flow rate. Volume rate of gas from time to time exceeds scheduled in eight times (80 and 10 thousand hours, respectively). Input concentrations of toluene and nefras periodically exceed for more than twice of the recommended norm. Despite the periodic increase in the concentrations of major pollutants above the regulatory standards at the outlet of the catalytic reactor routine concentration is not exceeded. The first batch of APKGS-20SH catalyst, loaded in July 2009 is stable to date. The catalyst can be recommended for use for air emissions clean units at enterprises of synthetic rubbers production.
