Hydrogenation of Vegetable Oils over Pd on Nanocomposite Carbon Catalysts

Abstract

Catalytic hydrogenation of vegetable oils was studied over Pd nanocomposite carbon catalysts. The mesoporous structure of the carbon support was beneficial to achieve fast hydrogenation rates and the desired cis/trans ratio of monoenic products of edible oil hydrogenation. The preparation procedure developed for a slurry catalyst was successfully utilized for fixed bed applications. Industrial experience of Pd/nanocomposite carbon utilization in selective hydrogenation of edible and total hydrogenation of nonedible oils is described.

Utilization of Triglycerides and Related Feedstocks for Production of Clean Hydrocarbon Fuels and Petrochemicals: A Review

“…The supported noble metal catalysts were proposed to be efficient deoxygenation catalysts [37] and their activity and selectivity were studied comprehensively by Murzin et al [34,[38][39][40][41][42][43][44][45][46]. The group was even awarded a patent covering the method of hydrocarbon production by using noble metal catalysts [47,48].…”

Diesel-like Hydrocarbons from Catalytic Deoxygenation of Stearic Acid over Supported Pd Nanoparticles on SBA-15 Catalysts

“…The main parameter under study is the effects of metal loading. The supported Pd nanoparticles that have large support surface area and porosity are reported to be more suitable for catalytic conversion of larger fatty acid molecules [13][14][15].…”

Molecular engineering approach in the selection of catalytic strategies for upgrading of biofuels

“…Issues with triglycerides arise from four molecular aspects: long‐chain lengths, olefin content, ester groups, and free fatty acids. The former two aspects can be improved through conventional processing well established in refinery operations, although selective hydrogenation of the olefin groups has been the focus of recent publications 25. The latter two, however, lead to problems with water solubility, storage, and corrosion.…”
