The invention relates to a method for manufacture of hydrocarbon fuels and oxygenated hydrocarbon fuels such as alkyl substituted tetrahydrofurans such as 2,5-dimethyltetrahydrofuran, 2-methyltetrahydrofuran, 5-methylfurfural and mixtures thereof. The method generally entails forming a mixture of reactants that includes carbonaceous material, water, a metal catalyst and an acid reacting that mixture in the presence of hydrogen. The reaction is performed at a temperature and for a time sufficient to produce a furan type hydrocarbon fuel. The process may be adapted to provide continuous manufacture of hydrocarbon fuels such as a furan type fuel.

A hydrotalcite-derived Ni-Al2O3 catalyst can catalyze HMF hydrogenation to DMF, DMTHF and DHMTHF with high yields (91.5%, 97.4% and 96.2% respectively).
Bioassay results were that most compounds had obvious inhibitoryactivity at 20 μg/mL. Compounds 5j, 5k, and 5l possessed outstanding inhibitoryactivity against B. cinerea. Their EC50 values were 0.540, 0.676, and 0.392 μg/mL, respectively. They owned better effects than fluxapyroxad (EC50 = 0.791 μg/mL). In the meantime, the inhibitoryactivity of 16 compounds was evaluated against SDH. It turned
An object of the present invention is to provide high-quality 1,4BG capable of working out to a raw material of PBT with good color tone, by efficiently removing and refining impurities mixed when producing a biomass-derived 1,4BG on an industrial scale. The present invention relates to a production method of refined 1,4BG, where a crude 1,4BG-containing solution is obtained from refined raw material 1,4BG obtained by removing bacterial cells, salt contents and water from the fermentation culture medium, through a step of removing high-boiling-point components and/or low-boiling-point components by distillation and/or a step of converting an unsaturated compound to a hydride and the target product is obtained as a side stream in a further distillation step.
At the time of producing a polyester by using a dicarboxylic acid component and a biomass-resource-derived diol as raw materials, a polyester is efficiently produced with good color tone. As the raw material diol derived from biomass resources, a diol in which the content of a cyclic carbonyl compound having a carbon atom number of 5 or 6 is from 0.01 to 12 ppm by mass, is used. By controlling the content of a cyclic carbonyl compound having a carbon atom number of 5 or 6 in the raw material diol to fall in a prescribed range, the color tone of the polyester is improved.
