This paper is a review of the developments in the field of catalytic hydroprocessing of biomass-derived liquefaction conversion products (bio-oil) over the past 25 years. Work has been underway, primarily in the U.S. and Europe, in catalytic…
-
Fast pyrolysis bio-oils currently produced in demonstration and semi-commercial plants have potential as a fuel for stationary power production using boilers or turbines but they require significant modification to become an acceptable…

PLS-regression (PLSR) is the PLS approach in its simplest, and in chemistry and technology, most used form (two-block predictive PLS). PLSR is a method for relating two data matrices, X and Y, by a linear multivariate model, but goes beyond…

Fast pyrolysis utilizes biomass to produce a product that is used both as an energy source and a feedstock for chemical production. Considerable efforts have been made to convert wood biomass to liquid fuels and chemicals since the oil crisis in…
-
The modern chemical industry relies heavily on homogeneous and heterogeneous catalysts. Understanding the operational mode, or reactivity, of these catalysts is crucial for improved developments and enhanced performance. As a result, various…

Biofuels offer the potential to substitute for a large proportion of fossil fuels, however it is considered that the utilisation of lignocellulosic biomass, via second-generation biorefining technologies, will be necessary for this to be achieved…
-
Single-layer MoS2 nanoclusters were synthesized on a Au substrate as a model system for the hydrotreating catalyst and studied by atomically resolved scanning tunneling microscopy (STM) in order to achieve atomic-scale insight into the interactions…
-
The pyrolysis of four biomasses (corn stalk, rice husk, sorghum straw, and wheat straw) was studied at different temperaturetime functions in an inert gas flow by thermogravimetric analysis (TGA). Linear and stepwise heating programs were employed.…
-
High-resolution scanning tunneling microscopy (STM) is used in combination with density-functional theory (DFT) to provide new insight into the morphology and atomic-scale structure of MoS2 nanoclusters in hydrodesulfurization (HDS) catalysts.…

Bio-oil (product liquids from fast pyrolysis of biomass) is a complex mixture of oxygenates derived from the thermal breakdown of the biopolymers in biomass. In the case of lignocellulosic biomass, the structures of three major components,…
-
By means of scanning tunneling microscopy (STM), it has been possible to obtain the first atomic-scale images of the Co-Mo-S structure present in hydrodesulfurization (HDS) catalysts. Information on the catalytically important edge structures has…
-
The pyrolysis behaviors of several agricultural residues have been investigated by using thermogravimetric analysis. The evolving rates of the gaseous products during the pyrolysis such asH2,CH4,H2O, CO and CO2 were also measured by the TG-MS…
-
Seven mesoporous catalysts were compared in how they can convert the pyrolysis vapours of spruce wood in order to obtain improved bio-oil properties. Four Al-MCM-41 type catalysts with a Si/Al ratio of 20, a commercial FCC catalyst, a pure siliceous…
-
A new group contribution method for the estimation of properties of pure organic compounds is presented. Estimation is performed at two levels: the basic level uses contributions from first-order groups, while the next higher level uses a small set…
-
The determination of the local structure of cobalt- or nickel-promoted MoS2-based hydrodesulfurization catalysts is of interest for understanding the mechanism leading to an increased activity brought by cobalt or nickel, the so-called synergetic…
-
We present density functional theory (DFT) calculations of reaction pathways for both the hydrogenation (HYD) and direct desulfurization (DDS) routes in the hydrodesulfurization (HDS) of thiophene over the different MoS2 edge structures, which will…
-
The crude bio-oil was upgraded in supercritical ethanol under hydrogen atmosphere by using Pd/SO42-/ZrO2/SBA-15 catalyst. This is a novel way to upgrade bio-oil with the combination of hydrotreatment, esterification, and cracking under supercritical…
-
Commercial catalysts, including zeolites (HZSM-5), fluid catalytic cracking (FCC) catalysts, transition metal catalysts (Fe/Cr), and aluminas, were successfully evaluated in a fixed bed catalytic reactor using a mixture of model compounds to…
-
Periodic effects form the basis for progress in understanding the role of structure/function relationships in hydrodesulfurization (HDS). Theoretical results of Toulhoat, and Raybaud et al. based on ab initio calculations using density functional…
