| 摘要 |
This invention provides a novel catalyst exemplified by cobalt-exchanged ZSM-5. The catalyst has unusual resistance to irreversible steam degradation. After long-term exposure to steam, it may be regenerated by sulfiding. The invention further provides a process for converting, in the presence of steam, compounds subject to catalytic conversion by acidic catalysts, including a process in which steam is inherently produced. The latter conversion is exemplified by the formation of higher carbon-numbered hydrocarbons from the lower alcohols or ethers thereof. |
