    Abstract: Furfural is produced from biomass material containing pentosan, in high yields, in a production process comprising treating the biomass with a solution containing at least one α-hydroxysulfonic acid thereby hydrolyzing the biomass to produce a product stream containing at least one C5-carbohydrate compound in monomeric and/or oligomeric form, and dehydrating the C5-carbohydrate compound in the presence of a heterogeneous solid acid catalyst, in a biphasic reaction medium comprising an aqueous phase and a water-immiscible organic phase, at a temperature in the range of from about 100° C. to about 250° C. to produce a dehydration product stream containing furfural. An aqueous stream is separated from the dehydration product, which can be optionally recycled to the hydrolysis step.

    Abstract: The present invention is directed to a method which includes the steps of: contacting an oil sand with a suitable solvent to generate a solvated oil sand slurry; separating solvent-diluted bitumen from the solvated oil sand slurry to generate (a) a solvent-diluted bitumen and (b) a slurry with increased solids concentration; filtering the slurry with increased solids concentration; dropping the solids into a pressure reduction vessel wherein the pressure in the pressure reduction vessel is a pressure below a vapor pressure of the solvent; and drying the solids removed from the pressure reduction vessel to produce solids having dry tailings. The method of the present invention may be used to produce a low ash bitumen product and dry tailings from oil sands.
