| 摘要 |
In making raw synthesis gas by catalytic steam reforming of hydrocarbons, such gas to be used in making ammonia, urea or alcohols, naphtha is used as a component of process feed and/or reformer fuel by resolving it into two or more of a top fraction (for process feed), a light fraction (for process feed or reformer fuel) and a heavy fraction (for reformer fuel or boiler fuel). Resolution is preferably by stripping with a gas available in the over-all process, for example natural gas, hydrotreater off-gas, unreacted purified synthesis gas or synthesis purge gas. |
