An improved process for catalytic reformers and their use for the catalytic reforming of petroleum naphthas. More particularly, the invention relates to an improved reformer unit which can be operated at higher throughput relative to compressor size. The invention utilizes pressure swing adsorption to improve the hydrogen content of hydrogen containing streams generated by and utilized in catalytic reforming processes. The invention also has the capability of enabling compressor-limited catalytic reforming units to be operated at increased capacities.

Catalytic reformer unit and unit operation

This invention relates to process for producing a reformate or gasoline product. The process involves a rapid cycle of reacting hydrocarbon feedstock to form the product and then regenerating the catalyst used in the reaction. The process can be carried out at relatively high liquid hourly space velocities and preferably at relatively low hydrogen to hydrocarbon ratios to produce a reformed product having relatively high liquid yield and hydrogen content.
