“…The glycerol portion of the triglyceride molecule is turned into propane by adding H 2 . Alternative route to convert the glycerides to FFAs is thermal hydrolysis [101][102][103]. Oils and fats that contain mostly triglycerides are converted into three moles of FFAs and one mole of glycerol by processing the feedstocks with three moles of water.…”

“…In recent years, catalytic (hydro)deoxygenation (HDO) has emerged as a promising technological step in the conversion of vegetable oil to biodiesel . HDO is a highly effective technology for removing oxygen atoms from the fatty acids in vegetable oils under high hydrogen pressures (up to 140 bar) and at high temperatures (250‐450 °C).…”

Molybdenum Nitrides, Carbides and Phosphides as Highly Efficient Catalysts for the (hydro)Deoxygenation Reaction

Transition metal nitrides, carbides and phosphides have the potential to replace the expensive and hazardous catalysts typically used for the conversion of fatty acids. However, there has been little research on the influence of treatment conditions and precursor nature on the properties of such catalytic systems. To better understand these dependencies, we synthesized a number of Mo catalysts by temperature‐programmed reduction (700‐900 °C; CH4/N2, N2/H2) using ammonium heptamolybdate, diammonium phosphate and hexamethylenetetramine (HMT) as Mo, C, N and P sources. The presence of HMT in the precursor mixtures ensured the synthesis of pure phase Mo2C, Mo2N and MoP. Catalytic activity in the (hydro)deoxygenation of stearic acid (240 min; 360 °C; 50 bar of H2) decreased in the following order: Mo2C>Mo2N>MoP. However, all of the studied Mo‐based catalysts showed good deoxygenation efficiency and, thus, represent excellent alternatives to traditional noble and sulfur‐containing catalysts.

“…Triglycerides, the main components of vegetable oils, animal fats, waste cooking oils and microalgae lipids, can produce straight chain alkanes, ranging from C8 to C18, that can be used for the production of aviation fuel67. At present, hydrodeoxygenation of triglycerides or free fatty acids is the main approach to producing aviation fuel from biomass891011.…”

Catalytic Decarboxylation of Fatty Acids to Aviation Fuels over Nickel Supported on Activated Carbon

Decarboxylation of fatty acids over non-noble metal catalysts without added hydrogen was studied. Ni/C catalysts were prepared and exhibited excellent activity and maintenance for decarboxylation. Thereafter, the effects of nickel loading, catalyst loading, temperature, and carbon number on the decarboxylation of fatty acids were investigated. The results indicate that the products of cracking increased with high nickel loading or catalyst loading. Temperature significantly impacted the conversion of stearic acid but did not influence the selectivity. The fatty acids with large carbon numbers tend to be cracked in this reaction system. Stearic acid can be completely converted at 370 °C for 5 h, and the selectivity to heptadecane was around 80%.
