摘要： Systems for dehydrogenating an alkane are provided. An exemplary system includes a furnace and further includes alkane heating chambers, regeneration mixture heating chambers, and two groups of reaction chambers, all located within the furnace. The alkane heating chambers and regeneration mixture heating chambers can preheat an alkane feed and a regeneration mixture feed, respectively. The two groups of reaction chambers can be switchably coupled to an alkane feed and a regeneration mixture feed such that an alkane can flow through one group of reaction chambers while a regeneration mixture flows through the other group of reaction chambers. Processes for dehydrogenating an alkane are also provided.

摘要： A method of operating a pyrolysis heater for reduced emissions of NO x and carbon monoxide. One or more wall burners 20, typically premix burners, are operated with more excess oxidant gas than one or more of the floor or hearth burners 10, which are typically non-premix burners. The invention takes advantage of different NO x emissions characteristics from different types of burners.
