摘要： The present invention relates to an integrated process for producing unsaturated carboxylic acids from the corresponding C2-C4 alkane. The process begins with performance of thermally integrated dehydrogenation reactions which convert a C2-C4 alkane to its corresponding C2-C4 alkene, and which involve exothermically converting a portion of an alkane to its corresponding alkene by oxidative dehydrogenation in an exothermic reaction zone, in the presence of oxygen and a suitable catalyst, and then feeding the products of the exothermic reaction zone to an endothermic reaction zone wherein at least a portion of the remaining unconverted alkane is endothermically dehydrogenated to form an additional quantity of the same corresponding alkene, in the presence of carbon dioxide and an other suitable catalyst. The alkene products of the thermally integrated dehydrogenation reactions are then provided to a catalytic vapor phase partial oxidation process for conversion of the alkene to the corresponding unsaturated carboxylic acid or nitrile. Unreacted alkene and carbon dioxide are recovered from the oxidation product stream and recycled back to the thermally integrated dehydrogenation reactions.

摘要： The inventors have discovered catalyst ignition promoters comprising one or more activated metals. The catalyst ignition promoters are easily prepared from a number of metal sources, including spent catalysts, are activated quickly and provide effective catalyst ignition independent of the quality of the metals that comprise the catalytic converter. The one or more activated metals comprising the ignition promoter are prepared by contacting them with one or more chemical treatments. The activated metal components are prepared into suitable articles, referred to as ignition strips, that are placed in contact with one or more oxidative coupling catalysts, typically in the form of gauzes. The ignition promoters reduce the activation energy for catalyst ignition (also referred to “light off”), enabling ignition of catalyst gauzes that are new, used, contaminated, damaged and combinations thereof at a relatively low auto-ignition temperatures.
