摘要： Piston deposits resulting from neutralizing combustion acids present in the lubricating oil circulating within the lubrication system of an internal combustion engine are reduced or eliminated by first contacting the acids with a soluble weak base in the piston ring zone of the engine to form soluble neutral salts containing the weak base and the combustion acids. Thereafter, the neutral salts are contacted with a heterogenous strong base immobilized within the lubrication system by outside of the piston ring zone. The strong base displaces the weak base from the neutral salts, returning the weak base to the oil for recirculation to the piston ring zone for further use. The remaining strong base/combustion acid salts are immobilized as deposits with the strong base rather than on the piston. In a preferred embodiment, trioctadecyl amine is the weak base and zinc oxide is the strong base. In a particularly preferred embodiment, the weak base is incorporated on a substrate, preferably a cement binder.

摘要： A filter system for use in a three-phase slurry reactor is provided. The filter system comprises one or more bundles of a plurality of filter elements for separating liquid from a mixture of liquid and solids contained in the reactor. Each filter bundle is connected to a product transfer conduit transporting separated liquid to a location outside of and downstream from the reactor. The transfer conduit is provided with means for backflushing the filter bundle and guard filter means.

摘要： Disclosed is a catalytic cracking process which incorporates a short contact time catalytic cracking step. The short contact time cracking step provides for an overall increase in distillate quality as well as provides for an overall increase in the quantity of light olefins product. After the short contact time reaction step, gasoline and high quality distillate products are separated from a gas oil containing bottoms fraction, and the gas oil containing bottoms fraction is reprocessed.

摘要翻译： 通过首先使酸与发动机的活塞环区域中的可溶性弱碱接触而形成可溶性中性盐，从而减少或消除存在于内燃机润滑系统内的润滑油中存在的中和燃烧酸的活塞沉积物，形成可溶性中性盐 弱碱和燃烧酸。 此后，中性盐与固定在润滑系统内的异质强碱接触，但在活塞环区外。 强碱将弱碱从中性盐中取代，将弱碱返回到油中再循环到活塞环区进一步使用。 剩余的强碱/燃烧酸盐作为沉积物固定为强碱而不是活塞。 在优选的实施方案中，三十八烷基胺是弱碱，氧化锌是强碱。 在特别优选的实施方案中，将强碱掺入基材，优选掺入水泥粘合剂。
