| 摘要 |
Petrochemicals (hydrocarbon derivatives) are produced by the vapour phase partial oxidation reaction of a hydrocarbon with air, if desired, enriched in oxygen, in the presence of a suitable catalyst. The petrochemical product is removed from the product gas stream, and part or all of the remaining gas stream is passed through a bed of hydrophobic adsorbent, which adsorbs mainly the unreacted hydrocarbon from the gas stream without adsorbing water vapour. The adsorbed hydrocarbon is purged from the bed with air, and the air-hydrocarbon mixture is recycled to the partial oxidation reactor. <IMAGE> |
