Highly selective, energy-free, and environmentally friendly one-pot production of linear α-olefin from biomass-derived organic acid in a dual-bed catalyst system

Abstract

Linear α-olefins (LAOs) such as 1-heptene and 1-octene are in high demand in the petrochemical industry. The increasing concerns about the environment and resource depletion have raised the importance of...

Highly Efficient N-Doped Carbon-Supported Subnanometer Cobalt–Zinc Bimetallic Catalysts for Decarbonylation of Fatty Acids into Long-Chain Olefins

“… , Although these systems demonstrate high activity and high yields of olefins, they usually face challenges such as the need for expensive organic ligands, low stability, the reliance on specific solvents and atmospheric conditions, and complex processes for separating the catalyst and purifying the product . As a result, alternative heterogeneous catalytic systems, including Pd/C, Pt/C, Ru/C, Rh/C, and Os/C, have been explored, but their ability to produce alkenes is limited, necessitating the addition of phosphine ligands or acid anhydrides as co-reactants. − Despite the development of noble metal alloy systems that eliminate the need for acid anhydrides, their widespread implementation is hindered by high costs and the scarcity of noble metals. − Currently, various supported non-precious metal catalysts for non-additive catalytic decarbonylation have been reported, including Cu, Fe, Ni, Mn, Co, etc. ,− These alternatives show great potential due to their economic viability. However, a significant challenge remains: these non-noble metal catalysts often suffer from severe cracking issues.…”
