Ammonia-assisted reforming and dehydrogenation toward efficient light alkane conversion

Abstract

The proven world reserves of natural gas are up to 7400 trillion cubic feet, providing cheap and abundant light alkane as feedstocks for chemicals and energy syntheses. However, efficient conversion...

Intermetallic Ni3Ga1 Catalyst for Efficient Ammonia Reforming of Light Alkane

“…Nonetheless, we believe that such a reaction could be employed for CO x -free H 2 production if the reaction can be realized at mild temperatures and green ammonia, as an H 2 carrier, is ubiquitously available from renewable energy. 16,17 Indeed, ammonia as a carbon-free H 2 carrier has been extensively recognized recently. 18−20 Considering that the market size of H 2 is larger than HCN, the catalytic hydrolysis (HCN + H 2 O → NH 3 + CO 21−23 or NaCN + H 2 O → HCOONa + NH 3 24,25 ) can be employed to convert HCN back to NH 3 .…”

“…Consequently, H 2 from the BMA process is frequently used as fuel for heating the reactor in the current industry. Nonetheless, we believe that such a reaction could be employed for CO x -free H 2 production if the reaction can be realized at mild temperatures and green ammonia, as an H 2 carrier, is ubiquitously available from renewable energy. , Indeed, ammonia as a carbon-free H 2 carrier has been extensively recognized recently. − Considering that the market size of H 2 is larger than HCN, the catalytic hydrolysis (HCN + H 2 O → NH 3 + CO − or NaCN + H 2 O → HCOONa + NH 3 , ) can be employed to convert HCN back to NH 3 . Although we understand HCN hydrolysis, currently, it is not employed in industry, and the process is of interest only for exhaust gas treatment.…”
