“…Mahfud et al [133] developed a liquid phase ruthenium catalysts for the hydrotreatment of the aqueous phase of bio-oil at mild conditions (50-90˚C and 2-4 MPa). Model bio-oil compounds were used and upon reaction amounts of reactive aldehydes were reduced significantly.…”

In this vein, fast pyrolysis of biomass and upgrading of the product is deemed to have potential as a technology solution. The objective of this review is to provide an update on recent laboratory research and commercial developments in fast pyrolysis and upgrading techniques. Fast pyrolysis is a relatively mature technology and is on the verge of commercialisation. While upgrading of biooils is currently confined to laboratory and pilot scale, an increased understanding of upgrading processes has been achieved in recent times.

“…Homogeneous catalysis offers a great potential for catalytic upgrading of bio-oil to avoid or slow down catalyst deactivation by coke deposition. Mahfud et al initially employed a homogeneous catalyst to hydrogenate two bio-oil model compounds (acetol and hydroxyacetaldehyde), and found that the hydroxyacetaldehyde could be effectively converted at a temperature lower than 90°C and a pressure lower than 45 bar [20].…”

A homogeneous RuCl 2 (PPh 3 ) 3 catalyst was prepared for the hydrogenation of bio-oil to improve its stability and fuel quality. Experiments were first performed on three model aldehydes of acetaldehyde, furfural and vanillin selected to represent the linear aldehydes, oxygen heterocyclic aldehydes and aromatic aldehydes in bio-oil. The results demonstrated the high hydrogenation capability of this homogeneous catalyst under mild conditions (55-90°C, 1.3-3.3 MPa). The highest conversion of the three model aldehydes was over 90 %. Furfural and acetaldehyde were singly converted to furfuryl alcohol and ethanol after hydrogenation, while vanillin was mainly converted to vanillin alcohol, together with a small amount of 2-methoxy-4-methylphenol and 2-methoxyphenol. Further experiments were conducted on a bio-oil fraction extracted by ethyl acetate and on the whole bio-oil at 70°C and 3.3 MPa. Most of the aldehydes were transformed to the corresponding alcohols, and some ketones and compounds with C-C double bond were converted to more stable compounds.

Abstract:The asymmetric hydrogenation of methyl acetoacetate (MAA) in methanol using dibromobis{(S)-4-phenyl-4,5-dihydro-3H-dinaphtho[2,1-c: 1',2'-e]phosphepine}-ruthenium was studied in detail. For the determination of the reaction network, data from kinetic experiments were compared to different possible reaction networks using the kinetic software Presto Kinetics. The simulation was optimised to describe the reaction accurately with a minimal set of process parameters and reaction equations. For the best model the reaction orders, collision factors and activation energy of all reaction steps were determined. Additionally, the influence of reaction temperature and hydrogen pressure on the enantiomeric excess (ee) of the reaction was studied. It was found that high reaction temperatures and high hydrogen pressures result in increasing enantioselectivities.
