In Fluid Catalytic Cracking (FCC)processes, widely used in oil refineries, the separation and recovery of powder catalysts is a major concern. Particularly, the concentration of catalyst after the FCC regenerator is usually over 150 mg/Nm3. Since these levels of emissions didn`t represent any environmental harm in the past, they were not controlled by any separator or filter. Plant managers main concern was to clean a fraction of the gas to produce energy in a Turbo Expander, or similar, while concentrating the...
After the proliferation of the Clean Air Act in 1970, the catalytic converter for automobiles was introduced as probably the most important technology in History to clean air pollution worldwide. Removing Carbon monoxide (CO), Hydrocarbons (HC) and nitrogen oxides (NOx), the catalysts contributed substantially to the elimination or reduction of smog in major cities in the USA and Worldwide.
The Applied Catalyst Activated Carbon Monolith (ACM) can be used for CO2 capture, H2S adsorption, and hydrocarbon adsorption. The porosity and high surface area of activated carbon is sufficient to allow for long-term capture and subsequent de-adsorption of various gases.
Applied Catalysts has a unique activated carbon monolith based catalyst (ACMC, link to Flyer) based on Applied Ceramic carbon honeycomb (ACM). The ACM has been commercialized in a number of gas adsorption applications, such as for evaporative emission control in automobiles. The ACMC catalysts can be used in most applications where catalysts are carbon supported with advantages for continuous process chemistries in flow reactors.
