Catalytic reforming is a chemical process used to convert naphthas from crude oil into liquid products called reformates, which are premium "blending stocks" for high-octane gasoline.

The most widespread process for rearranging hydrocarbon molecules is naphtha reforming. The initial process, thermal reforming, was developed in the late 1920s.

Convert heavy naphtha to gasoline and BTX aromatics using the technology preferred by more than 80% of all CCR reforming units. predominant reactions are endothermic, so an interheater is used between each reactor to reheat the charge to reaction temperature.

Sep 1, 2013 · Naphtha reforming is an endothermic reaction and contributes to temperature drop in the reactors. Thus, catalytic naphtha reformers are designed with multiple reactors and with heaters between the reactors to maintain reactor temperature at desired levels.

Jun 1, 2024 · This review focuses on the catalytic naphtha reforming process for aromatics production and makes special emphasis on reforming catalysts (evolution and recent novelties, as well as their deactivation, regeneration, and reactivation processes).

Oct 7, 2024 · The major process variables that affect the performance of the catalytic naphtha reforming or platforming unit are reactor pressure, reactor temperature, space velocity, hydrogen to hydrocarbon (H2/HC) molar ratio, feedstock properties, catalyst selectivity, activity, and …

Catalytic reforming converts low-octane, straight-run naphtha fractions, particularly heavy naphtha that is rich in naphthenes, into a high-octane, low-sulfur reformate, which is a major blending product for gasoline.

In catalytic reforming, naphthenic naphtha feeds produce higher reformate, aromatics, and hydrogen products relative to those for paraffinic naphtha. The five major reactions are naphthene dehydrogenation, isomerization of paraffins, paraffin dehydrocyclization, hydrocracking of paraffins, and hydrodealkylation of alkyl aromatics.

Catalytic naphtha reforming is a major process in the petroleum refinery that converts low value naphthas into high-octane reformate product for gasoline blending and into high-value aromatics for petrochemical processing.

The Introduction to Naptha Reforming training course explains how reforming relates to a refinery's operation. It also identifies reforming techniques, catalytic reformer types, and how variables affect the process.
