Abstract: The invention provides a continuous process for the preparation of ethylene glycol and 1, 2-propylene glycol from starting material comprising one or more saccharides, said process being carried out in a reactor system comprising a reactor vessel equipped with an external recycle loop and said process comprising the steps of: i) providing the starting material in a solvent, via an inlet, to the external recycle loop and contacting it therein with a retro-aldol catalyst composition to provide an intermediate stream; ii) then contacting said intermediate stream with hydrogen in the presence of a hydrogenation catalyst composition in the reactor vessel; iii) withdrawing a product stream comprising glycols from the reactor vessel; iv) providing a portion of said product stream, via an outlet, for separation and purification of the glycols contained therein; and v) recycling the remainder of said product stream via the external recycle loop.

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 an acid, 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 that can be optionally recycled to the hydrolysis step.
