INTEGRATED PROCESSES AND SYSTEMS FOR REFORMING AND ISOMERIZING HYDROCARBONS

摘要

Processes and systems are provided for reforming and isomerizing hydrocarbons to produce octane upgraded hydrocarbons. The process involves providing a reforming feedstream to a reforming zone containing a reforming catalyst and operating the reforming zone at reforming conditions including reforming pressure in a range of from 1 to 18 atmospheres to generate a reforming zone effluent. The reforming zone effluent is separated to form a net gas stream comprising primarily hydrogen and a liquid reforming product stream, and then providing the net gas stream and an isomerization feedstream to an isomerization zone containing an isomerization catalyst. The isomerization zone is operated at an isomerization pressure that is greater than the reforming pressure, to produce an isomerization zone effluent. The system for reforming and isomerizing hydrocarbons includes a reforming zone containing a reforming catalyst, a reforming separator, an isomerization zone containing an isomerization catalyst, and an isomerization separator.
