An Efficient Nickel Catalyst for the Reduction of Carbon

Jun 14, 2010 · Nickel hydride with a diphosphinite-based ligand catalyzes the highly efficient reduction of CO2 with catecholborane, and the hydrolysis of the resulting methoxyboryl species produces CH3OH in good yield. The mechanism involves a nickel formate, formaldehyde, and a nickel methoxide as different reduced stages for CO2. The reaction may also be catalyzed by an air-stable nickel formate.

influence of nickel-based catalysts on syngas production

Influence of nickel-based catalysts on syngas production

Syngas production (H2 and CO) from carbon dioxide reforming of high density polyethylene (HDPE) over Ni–Al catalyst was evaluated in a two-stage fixed bed reactor. Syngas production was favoured by CO2 addition, with the highest production of 138.81 mmolsyngas g− 1HDPE, which was about six times higher than non-catalytic, non-CO2 addition. The catalytic performances of nickel-based

Nickel catalyst with different supports for green diesel

Sep 01, 2019 · Methane (CH 4) and carbon dioxide (CO 2) were found in the gaseous product and CH 4 was the major gas presented in all catalysts. This result suggested that the methanation reaction between CO or CO 2 and fatty acids occurred due to methanation being strongly selective when the reaction was catalyzed by the Ni metal, as many studies have
