Catalyst Development for Higher Alcohol Synthesis (HAS)
MetadataShow full item record
This study investigated the effects of partial substitution at the A- and/or B-site of LaCoO3 perovskite catalysts (ABO3) on higher alcohol synthesis (HAS) from syngas. The catalyst properties and catalytic performances were well studied for the La1-xSrxCo1-y-zNiyCuzO3 catalysts. A-site substitution affected CO conversion, while B-site substitution affected higher alcohol selectivity. The effects of alkali promoters and reaction conditions were also discussed. This study proved that partially-substituted perovskites are promising candidates for the enhancement of HAS.
