摘要： Method for synthesizing L-2-oxothiazolidine-4-carboxylate and its acid, L-2-oxothiazolidine-4-carboxylic acid. The present invention involves the separation of phenol from a reaction mixture containing L-2-oxothiazolidine-4-carboxylate and phenol. In the present method a reaction mixture containing phenol, L-2-oxothiazolidine-4-carboxylate, and chloride salt, is contacted with a phenol adsorbing adsorption resin, the adsorption resin comprising a polymer having a polyethylene backbone. The adsorption resin is capable of adsorbing substantially all of the phenol while not adsorbing substantial amounts of the L-2-oxothiazolidine-4-carboxylate from the reaction mixture.

摘要： A process for treating a liquid comprising subjecting a liquid containing, in solution, citric acid as well as a less desirable component having a similar molecular weight to citric acid, to nanofiltration in a filtration step. From the filtration step, a permeate in which the ratio of the concentration of the citric acid to that of the less desirable component is greater than the ratio of the concentration of the citric acid to that of the less desirable component in the solution, is obtained.

摘要： A process which permits the facile conversion of green bananas to a sugar syrup uses a sequence of steps involving grinding the bananas, heating the bananas, treating the bananas with an alpha amylase to convert the starch granules into lower molecular weight molecules (liquefaction), changing conditions and treating the low molecular weight starch molecules and other substances in the liquefied fluid with the enzymes, amyloglucosidase, pectinase, cellulase, macerase, etc., filtering the resultant fluid to remove the solids, and, if necessary, evaporating the sugar solution to a suitable concentration. Use of elevated pH in each of the enzymatic conversion steps was found to greatly increase the glucose yield.

摘要： A method for increasing the sedimentation of mineral particles in feed liquids containing the same, particularly coal-derived liquids, by the use of an anti-solvent gas pressure technique. The mixture is held under a pressurized carbon dioxide atmosphere which causes an increase in the initial settling rate for sedimentation of the mineral particles from such liquids so that they may be used as fuels.

摘要： The present invention is directed to an improved wet air oxidation system and method for reducing the chemical oxygen demand (COD) of waste water used from scrubbers of coal gasification plants, with this COD reduction being sufficient to effectively eliminate waste water as an environmental pollutant. The improvement of the present invention is provided by heating the air used in the oxidation process to a temperature substantially equal to the temperature in the oxidation reactor before compressing or pressurizing the air. The compression of the already hot air further heats the air which is then passed in heat exchange with gaseous products of the oxidation reaction for "superheating" the gaseous products prior to the use thereof in turbines as the driving fluid. The superheating of the gaseous products significantly minimizes condensation of gaseous products in the turbine so as to provide a substantially greater recovery of mechanical energy from the process than heretofore achieved.

摘要翻译： 本发明涉及一种改进的湿式空气氧化系统和方法，用于降低用于煤气化装置的洗涤器的废水的化学需氧量（COD），该COD减少足以有效地消除废水作为环境污染物。 通过在氧化反应器中压缩或加压空气之前将氧化过程中使用的空气加热到与氧化反应器中的温度基本相等的温度来提供本发明的改进。 已经热空气的压缩进一步加热空气，空气然后与氧化反应的气态产物进行热交换，以在气体产物在涡轮机中作为驱动流体使用之前“过热”气态产物。 气态产品的过热显着地使涡轮机中的气态产物的冷凝最小化，从而提供比迄今为止实现的更大程度的机械能回收。

摘要： Reactive and sorbent materials including a non-encapsulated crosslinked biological material immobilized on a support matrix that includes a polyamine and at least one support material are described. The support material can be an inorganic or organic support material. The reactive and sorbent materials are formed by reacting the biological material with the polyamine, at least one support material, and a crosslinking agent. The materials exhibit enhanced properties generally, are capable of maintaining their reactive and sorbent properties in contact with digestive fluids, and exhibiting their reactive and sorbent properties as they pass throughout an organism's entire digestive system. Reactive and sorbent materials in contact with digestive juices at pH's ranging from about 3 to about 7 have maintained their reactive and sorbent properties for at least 4 hours.
