Catalytic naphtha reforming is a process in oil refineries that converts low-value heavy naphtha into high octane reformate, aromatics-rich feedstock, and hydrogen gas. The high octane reformate enhances gasoline quality, while the aromatics serve as essential petrochemical feedstocks, and the hydrogen is used in other refining processes. Typical catalysts for this process are platinum-based bi-functional catalysts supported by alumina and modified with chloride.

2. Introduction to Catalytic Naphtha Reforming
Catalytic reforming is the chemical process in oil refineries
that ;
• converting the low-value heavy naphtha fraction of crude
oil into high octane reformate
• aromatics rich feed-stock
• HydrogenGas
High octane reformate is a premium blending component for
a refinery gasoline pool with a 30~50 % share. The aromatics-
rich (benzene, toluene, and xylene) product serves as a vital
petrochemical feedstock. The hydrogen product is utilized in
other refinery hydroprocessing units.

3. Reforming Catalyst
Typical catalytic reformer catalysts are bi-functional that
comprised of platinum deposited on an alumina support,
one or two metals added as promoters or modifiers, and
chloride. The platinum on the alumina provides the metal
function and the alumina along with chloride provides the
acidic function. Both of the functions are required to
achieve the desired reforming reactions.
