    摘要： A method for the production of pentose syrup from hemicellulosic material comprising the separate steps of:(a) mixing said hemicellulose material with an acid selected from the group consisting of sulfuric and hydrochloric to obtain a final concentration of from about 1% to 15% at liquid:solid ratios between 0.1 and 4.0 whereby the material is ready for hydrolyzing directly or being stored for an indefinite period of time at ambient temperatures without degradation;(b) hydrolyzing the acidified material from step (a) by heating the material to a reaction temperature of from 90.degree. to 120.degree. C. for a period of time sufficient to hydrolyze substantially all of the hemicellulose;(c) leaching the hydrolyzed material at a temperature of from about 15.degree. to 100.degree. C. with an aqueous medium by percolating said medium through the hydrolyzed material at a velocity of 0.016 to 0.83 mm/sec; and(d) recovering a syrup containing at least 5 percent of pentoses whereby there is obtained a pentose syrup having a low PH and suitable for storage for extended periods of time without microbial degradation. The hydrolysis and leaching steps are carried out in a packed bed reactor. The resulting pentose syrup may be subsequently fermented to produce alcohol.

    摘要： A process is provided for increasing mixing in a regenerator. Streamlines of gas and some catalyst may form in a regenerator as a result of cyclone inlet horns positioned in the same direction. Overall mixing in the regenerator may decrease because of these streamlines. A dampening device may be used to interrupt the streamlines and increase mixing in the regenerator. The dampening device may be a baffle and direct streamlines from the outside of the chamber toward the center to collide and mix. In another embodiment, a dampening device may be a secondary disengager such as a T-disengager or an inverted can arrangement that may discharge gas and catalyst near the center of the upper chamber and interrupt the streamlines. In another embodiment, a dampening device may have swirl arms that redirect stream lines counter to the direction of flow.

    摘要： A process is disclosed for catalytically converting two feed streams. The feed to a first catalytic reactor may be contacted with product from a second catalytic reactor to effect heat exchange between the two streams and to transfer catalyst from the product stream to the feed stream. The feed to the second catalytic reactor may be a portion of the product from the first catalytic reactor.

    摘要： One exemplary embodiment can be an alkylation system including a catalyst regeneration zone. Generally, the catalyst regeneration zone includes first and second columns. The first column can provide an overhead stream having a catalyst and a first hydrocarbon, a side-stream having the catalyst and water, and a bottom stream having a second hydrocarbon. Typically, the second column receives the side-stream as a feed.
