Honeycomb Ceramic Monolith Catalyst Support Stone Monoliths Alumina Porcelain Heat Accumulator

Product Description
Ceramic honeycombs are used in regenerative thermal oxidizer (RTO) and regenerative catalytic oxidation (RCO) devices to destroy hazardous air pollutants (HAPs), volatile organic compounds (VOCs) and odorous emissions etc.
According to different process requirements of exhaust gas treatment (RTO, RCO), our company develop and produce a variety of materials and sizes of ceramic honeycomb products. Products have large surface area, small resistance loss, low thermal expansion coefficient, high water absorption, good crack resistance, moderate millipore aperture and other characteristics, have been widely used in RTO, RCO equipment at home and abroad.
Material: Alumina porcelain, Dense cordierite, Porous cordierite, Porous mullite, Stoneware porcelain, etc.
Size: According to customers’ requirements.Alumina Ceramic
