| 摘要 |
The present invention provides a process for producing aromatic hydrocarbons and ethylene, comprising: a. contacting a lower alkane feed comprising at least one of ethane, propane and butane with an aromatic hydrocarbon conversion catalyst within an alkane-to-aromatic zone to obtain at least hydrogen and aromatic reaction products, including at least benzene; b. converting an oxygenate feedstock in an oxygenate-to-olefin zone to obtain olefins, including at least ethylene; wherein at least part of the oxygenate feedstock is obtained by providing at least part of the hydrogen obtained in step a) and a feed containing carbon monoxide and/or carbon dioxide to an oxygenate synthesis zone and synthesizing oxygenates. In another aspect the invention provides an integrated system for aromatic hydrocarbons and ethylene and the use of hydrogen obtained from a process to convert lower alkanes to benzene to produce an oxygenate feed for an oxygenate-to-olefin process. |
