The honeycomb ceramic has the characteristics of high surface area, small resistance, strong thermal capacity, small coefficient of thermal expansion, strong chemical corroding resistance and excellent thermal shock resistance.
As a storage material of regenerative thermal oxidation and catalytic oxidation (RTO, RCO) equipment for volatile organic compounds (VOC) and hazardous air pollutants (HAP) removal, honeycomb ceramic heat accumulator has been widely used in petrochemical processes, as well as kinds of industries using organic solvents, such as painting, printing, metal degreasing and degreasing, adhesives, pharmaceuticals, plastics, rubber processing industry, chemical industry, high-temperature regenerative air purification, industrial waste gas treatment, gas purification system of harmful waste incineration.
