Numerical simulation of particle/monolithic two-stage catalyst bed reactor for oxidative coupling of methane

- 3D models were set up for OCM reactors using computational fluid dynamics method.
- The effects of catalyst bed heights on reactor performance were investigated.
- The simulated reactor performance matched well with the experimental.
- The monolithic catalyst bed had a higher C2 selectivity than the particle bed did.
- Effects of residence time and the CO2 blocking decided the reactor performance.
