Catalytic Light Hydrocarbon Upgrading under Methane Environment
The catalytic light hydrocarbon upgrading is explored under methane environment over metal modified zeolites. This novel process not only replaces naturally unavailable hydrogen with methane in the upgrading process, but also converts methane into value added products such as fuels and aromatic …
