Selective adsorption removal of carbonyl molecular foulants from real fast pyrolysis bio-oils

Chemical Composition of Bio-oils Produced by Fast Pyrolysis of Two Energy Crops†

Bio-oils from the fast pyrolysis of switchgrass forage and two sets of alfalfa stems (from two stages of developmentsbud and full flower stages) have been analyzed by wet-chemical methods, GC-MS, and HPLC. The chemical composition of bio-oil is important because it may give insights into its quality, stability, or suitability for downstream upgrading. Pyrolysis experiments were conducted at 500...

Removal of Organobromine Compounds from the Pyrolysis Oils of Flame Retarded Plastics Using Zeolite Catalysts

Two flame retarded plastics have been pyrolysed in the presence of two Zeolite catalysts to remove the organobromine compounds from the derived pyrolysis oil. The flame retarded plastics were, acrylonitrile – butadiene – styrene (ABS) that was flame retarded with tetrabromobisphenol A and high-impact-polystyrene (HIPS) that was flame retarded with decabromodiphenyl ether. The two catalysts inve...

Hydrotreating of fast pyrolysis oils from protein-rich pennycress seed presscake

The fast pyrolysis oils produced from proteinaceous biomass, such as pennycress presscake differ significantly from those produced from biomass with mostly lignocellulosic composition. Those from proteinaceous biomass tend to be deoxygenated, contain more nitrogen, be less acidic and be more stable. Because their composition is different, their behavior in and products from upgrading via hydrot...
