CO2 reforming of methane over Zr-promoted Ni/SBA-15 catalyst : effect of zirconium loading

In the present time, increased concerns on anthropogenic greenhouse gas emissions and abundance of natural gas resources have renewed interest in the CO2 (dry) reforming process as an alternative to steam reforming for synthesis gas production from natural gas. The catalytic performance of catalyst...
