Metgas Production from Bi-reforming of Methane over La-modified Santa Barbara Amorphous-15 Supported Nickel Catalyst

An integrated process of steam reforming coupled with CO2 reforming of methane (bi-reforming) has emerged as a promising reforming technique among pre-existing technologies. Syngas with a H2/CO ratio of about 2 (called Metgas) is desirable for the production of methanol and liquid hydrocarbons. La-...
