Abstract: Process for gas-phase polymerization carried out in two interconnected polymerization zones, to which one or more &agr;-olefins CH2═CHR are fed in the presence of catalyst under reaction conditions and from which the polymer product is discharged. The process is characterized in that the growing polymer flows through a first polymerization zone under fast fluidization conditions, leaves said first zone and enters a second polymerization zone through which it flows in a densified form under the action of gravity, leaves said second zone and is reintroduced into the first polymerization zone, thus establishing a circulation of polymer around the two polymerization zones. The novel process allows olefins to be polymerized in the gas phase with high productivity per unit volume of the reactor without incurring the problems of the fluidized-bed technologies of the known state of the art.

Abstract: The operation of a hydrocarbon synthesis reactor and catalyst distributed in the reaction slurry therein are improved by the presence in said reactor of one or more vertical downcomers open at both ends with gas disengaging areas located at their top end. The downcomer which circulates catalyst from the top of the reaction slurry to the bottom of said slurry is fully immersed in the reaction slurry and preferably extends from just above the bottom of the reaction zone of the reaction vessel to just below the top surface of the reaction slurry. The bottom end of said downcomer is shielded from intrusion of rising synthesis gas by the placement of a baffle which blocks rising gas entry but facilitates the exit of catalyst and liquid from the bottom of said downcomer and distributes them radially throughout the adjacent reactor slurry.

Abstract: An apparatus and method for blending a solute and a solvent to form a solution product which substantially eliminates starting material and product operational loss while improving environmental safety both in the workplace and the ambient atmosphere. The apparatus and method employ a closed system and controls which remove substances from the overhead vapors generated in the various units by employing separate and distinct filtering systems. A high efficiency particulate air filter (HEPA) is employed in a closed solute supply means. A demister device is in fluid communication with the vent of the mixing vessel unit to remove solvent and solution products, to form droplets from the exhaust stream and return them to the mixing tank and discharging the exhaust stream without stress to the environment.

Abstract: A hybrid reactor arrangement provides a reactive design that achieves higher acrylonitrile yield and lower catalyst circulating rate. The hybrid reactor design first passes a mixture of reactants and catalyst through a circulating bubbling bed reaction section. Heat exchange coils or other cooling medium in the bubbling bed reactor section maintain temperature in a range that will maximize the selectivity of reactants to the acrylonitrile product. The bubbling bed reactor section provides the initial conversion of the reactant. A circulating fluidized bed reaction zone finishes the conversion of reactants to a high yield under conditions that reduce the occurrence of secondary reactions that could otherwise produce unwanted by-products. The circulating fluidized bed reactor section maintains nearly plug flow conditions that allow continued conversion of unreacted feed components through primary reactions while limiting the time for secondary reactions to continue and diminish the final yield of products. Selectivity and conversion may also be improved by sequential addition of oxygen into the CFB reaction section. The sequential addition of oxygen may occur by the direct injection of an oxygen-containing gas or by the delivery of re-oxidized catalyst particles that are fully recharged with the lattice oxygen necessary for the reaction. Through this method the hybrid reactor provides the typical 5% improvement of higher acrylonitrile product yield from CFB-type reaction zones while reducing the required catalyst circulation by a factor of 10 or more.

Abstract translation: 混合反应器装置提供了实现较高丙烯腈产率和较低催化剂循环速率的反应性设计。 混合反应器设计首先将反应物和催化剂的混合物通过循环鼓泡床反应段。 鼓泡床反应器部分中的热交换盘管或其它冷却介质将温度保持在使反应物对丙烯腈产物的选择性最大化的范围内。 起泡床反应器部分提供反应物的初始转化。 循环流化床反应区在减少可能产生不需要的副产物的次级反应的情况下，完成反应物转化为高收率。 循环流化床反应器部分保持几乎堵塞流动条件，其允许未反应的进料组分继续转化通过初级反应，同时限制二级反应的持续时间并降低产物的最终产率。 还可以通过将顺序加入到CFB反应部分中来提高选择性和转化率。 氧的顺序添加可以通过直接注入含氧气体或通过输送用反应所需的晶格氧充分再充电的再氧化的催化剂颗粒进行。 通过该方法，混合反应器提供了CFB型反应区中较高丙烯腈产物产率的典型的5％的改进，同时将需要的催化剂循环减少10倍或更多。
