A method of generating a refined sugar stream that comprises xylose from a biomass hydrolysis solution, including contacting a biomass hydrolysis solution that includes a population of mixed sugars comprising xylose, an acid, and impurities, with a thermally-phase separable solvent such as a glycol solvent to form an extraction mixture; and separating from said extraction mixture a first stream including the thermally-phase separable solvent, acid, and impurities and a second, refined sugar stream that comprises xylose. The thermally-phase separable solvent is an ethylene glycol or a propylene glycol ether, such as 2-butoxyethanol or 1-propoxy-propanol or any combination thereof.

PROCESS FOR THE SEPARATION OF PINITOL FROM A CAROB EXTRACT

A process for separating at least one inositol from a carob extract, may include: chromatographically separating pinitol a first carob extract in at least one passage on a chromatographic resin, thus obtaining an aqueous solution comprising the pinitol in a range of from 35 to 70 wt. 8, based on a total aqueous solution weight, the aqueous solution having a Brix value of 20 or lower. The first carob extract may be filtered and demineralized carob extract having a Brix value greater than 60 and comprising the pinitol in a range of 5 to 25 wt. %, based on a total first carob extract weight.

Method for operating a chromatography setup

A method for operating a chromatography setup of a bioprocess installation with a plurality of chromatography columns, each with a column inlet and a column outlet, and a valve switching cassette with a group of inlet ports, a group of outlet ports, a group of column-in ports and a group of column-out ports. It is prosed, that a first liquid stream of concentrated buffer is introduced into a first internal liquid line via a first inlet port and that a second liquid stream of diluent is introduced into a second internal liquid line via a second inlet port, that in a dilution process, the array of valve units is switched as to create a third liquid stream by merging the first liquid stream and the second liquid stream at a merging location within the valve switching cassette.

Phosphonic acid catalyst in dehydrative cyclization of 5 and 6 carbon polyols with improved color and product accountability

A process for preparing cyclic dehydration products from sugar alcohols is described. The process involve using a mixed-acid catalyst reaction mixture containing a reducing acid, having a pKa of about 1.0-1.5, and at least a strong Brnsted acid or a Lewis acid, having a pKa0, or both acids in a solution to dehydrate and ring close said sugar alcohol. Synergistically, the mixed-acid catalysis can produce greater amounts of the desired product at similar levels of compositional accountability than either of the component acid catalysts acting alone.

Paraxylene separation process

A process for producing paraxylene is provided. The process includes separating a first mixture of C.sub.8 aromatic hydrocarbons in a simulated moving bed apparatus using a desorbent to produce (i) an extract comprising 50.0 wt % of the paraxylene in the first mixture; (ii) a desorbent-rich raffinate comprising 75 wt % of the desorbent withdrawn, and (iii) an desorbent-lean raffinate comprising 25 wt % of the desorbent withdrawn in the desorbent-rich and desorbent-lean raffinates. The desorbent-lean raffinate can then, without an intervening separation step, be passed to a refinery process or a vapor phase isomerization reaction to produce an effluent comprising paraxylene in a greater concentration than the desorbent-lean raffinate. The desorbent-rich raffinate can be passed to a liquid phase isomerization reaction to produce an effluent comprising paraxylene in a greater concentration than the desorbent-rich raffinate.
