摘要： A process for enhancement of the cetane number of a diesel fuel which in one embodiment comprises:(1) treating a diesel oil with a nitrogenous treating agent in a nitrogen amount, equivalent on a 100% nitric acid basis, to about 10 weight percent or less of the diesel oil feed;(2) separating unreacted nitrogenous treating agent from the diesel oil of step (1);(3) treating the diesel oil of step (2) with an inorganic alkali to produce a treated diesel oil; and(4) blending the treated diesel oil of step (3) with an untreated diesel oil to produce a blended diesel fuel such that the added nitrogen content in the blended diesel fuel is(a) about 300 ppm or less of nitrogen added when the diesel oil treated in step (1) is obtained from virgin diesel oil stock; or(b) about 450 ppm or less of nitrogen added when the diesel oil treated in step (1) is obtained from hydrotreated diesel oil stock.
摘要翻译：一种用于增强柴油燃料十六烷值的方法，其在一个实施方案中包括：（1）用含氮量（基于100％硝酸当量）的含氮处理剂将柴油处理至约10重量％或少柴油饲料; （2）从步骤（1）的柴油中分离未反应的含氮处理剂; （3）用无机碱处理步骤（2）的柴油以制备经处理的柴油; 和（4）将经处理的步骤（3）的柴油与未处理的柴油混合以产生混合的柴油燃料，使得混合柴油燃料中加入的氮含量为（a）当加入的柴油中添加约300ppm或更少的氮时，在步骤（1）中处理的柴油由原始柴油原料获得; 或（b）当从加氢处理的柴油原料获得在步骤（1）中处理的柴油时，加入的氮约为450ppm以下。

摘要： A process for the recovery of carbon disulfide from a flue gas. A stream of sulfur dioxide is removed from a flue gas and introduced into a first reduction reactor containing a chromium promoted iron oxide catalyst where the sulfur dioxide is reduced to carbonyl sulfide. The carbonyl sulfide is introduced into a second reduction reactor which contains an active alumina catalyst. The carbonyl sulfide decomposes to carbon disulfide which is recovered.
摘要翻译：从烟道气中回收二硫化碳的方法。将二氧化硫流从废气中除去，并引入含有铬促进的氧化铁催化剂的第一还原反应器中，其中二氧化硫还原成硫化羰。将羰基硫化物引入含有活性氧化铝催化剂的第二还原反应器中。羰基硫化物分解成回收的二硫化碳。

摘要： A copolymer of maleic anhydride and an alkyl vinyl ether is stabilized by contacting same with a non-reactive substantially moisture free gas at a temperature of from about 30.degree.-100.degree. C. for from about 0.5-24 hours. The copolymer is preferably prepared by reacting together maleic anhydride and an alkyl vinyl ether in the presence of a free radical initiator.
摘要翻译：通过使马来酸酐和烷基乙烯基醚的共聚物在约30℃-100℃的温度下与非反应性基本上不含水分的气体接触约0.5-24小时来稳定。共聚物优选通过使马来酸酐和烷基乙烯基醚在自由基引发剂的存在下反应来制备。
