Indium an efficient co-catalyst in novel Cu or Ni catalysts for selective reduction of biomass derived fatty acids to alcohols, in Indium: Properties, Technological Applications and Health Issues [PDF]

open access: yes, 2013
Supported copper or especially nickel catalysts are very important for hydrogenation of various organic compounds in the practice. Activity, selectivity and stability can be greatly improved using co-catalysts: e.g.

Effect of Mesopore Structural Parameters in Alumina Supports on Catalytic Hydrodeoxygenation of Guaiacol to Cycloalkanes via Ni-Supported Al2O3 Catalysts

open access: yesEnergies
The elevated oxygen content in lignin-derived oil restricts its direct application as a liquid fuel. Ni-based Al2O3 catalysts are commonly employed to enhance the quality of lignin-derived oil via the hydrodeoxygenation (HDO) process.

Hydrodeoxygenation of fatty acid methyl ester in gas oil blend–NiMoS/alumina catalyst

open access: yesGreen Processing and Synthesis, 2018
Hydrotreating of 10% fatty acid methyl ester (FAME) blended in gas oil was carried out by an NiMo-S/alumina catalyst and performed at an elevated temperature (300–400°C), a space velocity of 0.7–1.5 1/h and pressure 5 MPa.

Direct catalytic conversion of cellulose to liquid straight-chain alkanes [PDF]

open access: yes, 2014
High yields of liquid straight-chain alkanes were obtained directly from cellulosic feedstock in a one-pot biphasic catalytic system. The catalytic reaction proceeds at elevated temperatures under hydrogen pressure in the presence of tungstosilicic acid,

Hydrodeoxygenation of phenol over Pd catalysts by in-situ generated hydrogen from aqueous reforming of formic acid [PDF]

open access: yes, 2016
Hydrodeoxygenation of phenol, as model compound of bio-oil, was investigated over Pd catalysts, using formic acid as a hydrogen donor. The order of activity for deoxygenation of phenol with Pd catalysts was found to be: Pd/SiO2 > Pd/MCM-41 > Pd/CA &

Hydrodeoxygenation of stearic acid over Co-Mg-Al-O mixed oxide catalysts

open access: yesChimica Techno Acta
The influence of the Co/Mg molar ratio on the physicochemical and catalytic properties of Co-Mg-Al-O mixed oxides obtained by thermal treatment of layered double hydroxides (LDH) was investigated. Characterization of the mixed oxides by ICP, XRD, and TPR

Understanding and controlling the structure and segregation behaviour of AuRh nanocatalysts [PDF]

open access: yes, 2016
Heterogeneous catalysis, which is widely used in the chemical industry, makes a great use of supported late-transition-metal nanoparticles, and bimetallic catalysts often show superior catalytic performances as compared to their single metal counterparts.

A numerical model for the fractional condensation of pyrolysis vapours [PDF]

open access: yes, 2015
Experimentation on the fast pyrolysis process has been primarily focused on the pyrolysis reactor itself, with less emphasis given to the liquid collection system (LCS). More importantly, the physics behind the vapour condensation process in LCSs has not
