摘要： Oxidative dehydrogenation of paraffins to olefins provides a lower energy route to produce olefins. Oxidative dehydrogenation processes may be integrated with a number of processes in a chemical plant such as polymerization processes, manufacture of glycols, and carboxylic acids and esters. Additionally, oxidative dehydrogenation processes can be integrated with the back end separation process of a conventional steam cracker to increase capacity at reduced cost.

摘要： Oxidative dehydrogenation catalysts comprising MoVNbTeO having improved consistency of composition and a 25% conversion of ethylene at less than 420° C. and a selectivity to ethylene above 95% are prepared by treating the catalyst precursor with H2O2 in an amount equivalent to 0.30-2.8 mL H2O2 of a 30% solution per gram of catalyst precursor prior to calcining.

摘要： In the operation of an oxidative dehydrogenation (ODH) process, it is desirable to remove oxygen in the product stream for a number of reasons, including to reduce oxidation of the product. This may be achieved by having several pre-reactors upstream of the main reactor having a catalyst system containing labile oxygen. The feed passes through one or more reactors saturated with labile oxygen. When the labile oxygen is consumed through a valve system, the pre-reactor accepts product from the main reactor and complexes reactive oxygen in the product stream until the catalyst system is saturated with labile oxygen. Then the reactor becomes a pre-reactor and another pre-reactor becomes a scavenger.

摘要： A catalyst for oxidative dehydrogenation (ODH) of ethane with an empirical formula Mo—V—Te—Nb—Pd—O produced using a process comprising impregnation of the Pd component on the surface of the catalyst following a calcination step using a Pd compound free of halogens. The resulting catalyst can be used in both diluted and undiluted ODH processes and shows higher than expected activity without any loss of selectivity.

摘要翻译： 在氧化脱氢（ODH）方法的操作中，由于若干原因，包括减少产物的氧化，需要除去产物流中的氧。 这可以通过在主反应器上游具有包含不稳定氧的催化剂体系的几个预反应器来实现。 进料通过一个或多个饱和不稳定氧气的反应器。 当通过阀门系统消耗不稳定的氧气时，预反应器接受来自主反应器的产物，并使产物流中的活性氧复合，直到催化剂体系饱和不稳定的氧气。 然后反应器成为预反应器，另一个预反应器成为清除剂。
