MOF-derived Co nanoparticle on nitrogen-rich carbon for fatty acid hydrotreatment into green diesel

Compositional dependence of Co- and Mo-supported beta zeolite for selective one-step hydrotreatment of methyl palmitate to produce bio jet fuel range hydrocarbons

“…3 -desorption peak shi from high temperature to low temperature while maintaining a similar total amount (see also Table1). Noticeably, group III showed a dramatic decrease in the NH 3 -desorption peak at high temperature and the position of the peak also appeared at higher temperature range of 410-430 °C, unlike 380-400 °C in group II.…”

“…By utilizing diverse biomass sources consisting of triglycerides and free fatty acids (FFAs), biomass-derived fuel is a promising candidate to substitute conventional fossil fuels with green biofuel. [1][2][3] The common commercialized technology for converting biomass to biofuel is the transesterication of triglycerides or esterication of free fatty acids (FFAs) with methanol, which produces fatty acid methyl esters (FAMEs). However, because of the high oxygen content, out of jet fuel range hydrocarbons, and low isomerization degree, FAMEs have poor combustion properties such as low heating value, thermal instability, and high freezing point.…”

Carbon-Coated NiMoOx Bimetallic Catalyst for Selective Hydrodeoxygenation of Lipids to Fatty Alcohols

“…According to previous reports, hydrogen activation and substrate adsorption are two key steps in this transformation, but most non-noble metals can only effectively promote one step. For example, Ni and Co have particularly strong abilities to activate hydrogen gas, , while Mo and Nb exhibit excellent adsorption properties for fatty acids and their derivatives. , With that in mind, lots of non-noble-metal-based bimetallic catalysts have been developed for the transformation. − A Cu-NbO x /SBA-15 catalyst has been fabricated for highly efficient production of fatty alcohol via the HDO of fatty acid. The adsorption of fatty acid is promoted by NbO x , which also results in electron-deficient and highly dispersed Cu species .…”
