Catalytic conversion of lignin pyrolysis model compound- guaiacol and its kinetic model including coke formation
Lignin is the most difficult to be converted and most easy coking component in biomass catalytic pyrolysis to high-value liquid fuels and chemicals. Catalytic conversion of guaiacol as a lignin model compound was conducted in a fixed-bed reactor over ZSM-5 to investigate its conversion and coking behaviors. The effects of temperature, weight hourly space velocity (WHSV) and partial pressure on ...
متن کاملModeling Transport Phenomena in Selective Catalytic Reductant Catalytic Converter with NH3 as Reductant for NO Degradation
In the current study, reduction of nitrogen oxide from exhaust gas in the presence of NH3 as reductant on selective catalytic reductant (SCR) impregnated catalytic converter was simulated using Comsol© software. Mass transfer (one-dimensional) and heat transfer (three-dimensional) governing equations were taken into account to model the unsteady state behavior of the catalytic converter. Modeli...
متن کاملCatalytic transformation of carbohydrates and lignin in ionic liquids
Ionic liquids with anions of strong hydrogen-bond basicity have been broadly reported in the literature as effective solvents for the dissolution of the components of lignocellulosic biomass. The key attributes of various ionic liquids are reviewed with a focus on their structural and functional properties related to biomass dissolution capacity. A number of the most studied ionic liquids with ...
متن کاملCatalytic Oxidation and Depolymerization of Lignin in Aqueous Ionic Liquid
Lignin is an integral part of the plant cell wall, which provides rigidity to plants, also contributes to the recalcitrance of the lignocellulosic biomass to biochemical and biological deconstruction. Lignin is a promising renewable feedstock for aromatic chemicals; however, an efficient and economic lignin depolymerization method needs to be developed to enable the conversion. In this study, w...
متن کاملSelective catalytic conversion of guaiacol to phenols over a molybdenum carbide catalyst.
An activated carbon supported α-molybdenum carbide catalyst (α-MoC1-x/AC) showed remarkable activity in the selective deoxygenation of guaiacol to substituted mono-phenols in low carbon number alcohol solvents. Combined selectivities of up to 85% for phenol and alkylphenols were obtained at 340 °C for α-MoC1-x/AC at 87% conversion in supercritical ethanol. The reaction occurs via consecutive de...
