VOC waste gas treatment catalysts

Volatile organic compounds(VOCS) refers to the benzene, alcohols, aldehydes, phenol, ether, ketone, and mephitic gas, etc. The main sources of VOCs is painting, printing, petroleum refining, pharmacy, plastic materials and gum polymer process. Treatment of VOCs is very important and difficult in most actual occasions. Temperature of catalytic combustion is 180-500°C, Purification is 90-99% with related initiative temperature, no secondary pollution (NOX). VOC (Volatile Organic Compounds) Catalyst is formed by the first carrier cordierite honeycomb ceramic, second carrier γ-Al2O3 and the active components noble metal Pd and Pt. It is the new high efficient catalyst for VOC waste gas. 1. Product Features Widely application – It can be applied to the industrial waste gas purification which mainly contains monoxide, hydrocarbon and related oxide ramification.Lower gas-flowing resistance, lower initiative temperature for reaction, high active function, wide range for air speed. When the hydrocarbon concentration is within 500-900 mg/m3, the speed range is within 15000 -30000 h-1, the initiative temperature for the reaction is within 180 -300 centigrade, it can achieved more than 98% purification efficiency.2. Application Area It can be used for noxious waste gas containing hydrocarbon and monoxide chemicals. Such gas is from many industries such as chemical, food, mechanical, instrument and meters, Household Appliances, painting, insulating material and colorful steel. 3.
