Menetelmä hiilivetyjen osittaishapetustuotteiden valmistamiseksi

摘要

An alkene stream which contains a corresponding alkane as an impurity or a propylene stream which contains alkane as an impurity is subjected to adsorption at a temperature of 50 to 200 DEG C in a purifier A utilising an adsorbent which selectively adsorbs the alkene, thereby adsorbing substantially all of the alkene. The purified alkene is subjected to partial oxidation in a reactor B the presence of oxygen and, optionally ammonia or chlorine to produce various partial oxidation products. The process is operated on a low per pass conversion with recycle of unreacted alkene. In the system of the invention the purifier A may be upstream of the partial oxidation reactor B (i.e. receives all the fresh hydrocarbon feed to the process) or downstream of the reactor B (i.e. the reactor B receives the fresh hydrocarbon feed to the process). The alkane and alkene may both either contain three carbon atoms, the alkene being propylene, or two carbon atoms.
