Our catalyst is mainly used in formaldehyde, acetaldehyde, glyoxal production, with a large specific surface area, thermal stability, the system resistance, high purity, anti-drug capability, mechanical stability, use of our products can be increase in formaldehyde production, improve the methanol conversion rate, a longer catalyst life, formic acid generation rate is low, and reduce costs. At present the yield of tons of formaldehyde can be reduced to 440KG below consumption.
