In practice, industrial catalysts typically consist of both "zeolitic components" and "non-zeolitic components," which together play important roles in processes like polyolefin catalytic cracking and ...

Introducing interconnected mesopores and macropores into microporous zeolites with the rationalized pore size at each level is an effective strategy to suppress the diffusion limitations, but remains ...

This paper deals with a free-moving boundary diffusion model which describes a catalytic diffusion-reaction process in a gas-solid system with catalyst decay. We consider a one-phase free boundary ...

Incorporating interconnected mesopores and macropores into microporous zeolites with rationalized pore size at each level is an effective approach for overcoming diffusion limitations. Still, ...

Our earlier experimental study has shown that exhaust unburnt hydrocarbon emissions from spark-ignition engines can be reduced effectively by using in-cylinder catalysts on the surface of the piston ...
