What is catalytic reforming process?
Catalytic reforming is a chemical process used to convert petroleum refinery naphthas distilled from crude oil (typically having low octane ratings) into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline.
Which is the most effective catalysts for catalytic reforming?
Most processes use platinum as the active catalyst. Sometimes platinum is combined with a second catalyst (bimetallic catalyst) such as rhenium or another noble metal. There are a number of different commercial catalytic reforming processes.
What is the catalyst used in the reforming of petroleum?
Catalytic reforming uses a catalyst, usually platinum, to produce a similar result. Mixed with hydrogen, naphtha is heated and passed over pellets of catalyst in a series of reactors, under high pressure, producing high-octane gasoline.
What is thermal reforming?
Thermal reforming alters the properties of low-grade naphthas by converting the molecules into those of higher octane number by exposing the materials to high temperatures and pressures. Catalytic reforming uses a catalyst, usually platinum, to produce a similar result.
Which catalyst is used in reforming?
Catalytic reforming uses a catalyst, usually platinum, to produce a similar result. Mixed with hydrogen, naphtha is heated and passed over pellets of catalyst in a series of reactors, under high pressure, producing high-octane gasoline.
What is the difference between isomerization and reforming?
Catalytic reforming is the process of transforming C7–C10 hydrocarbons with low octane numbers to aromatics and iso-paraffins which have high octane numbers. It is a highly endothermic process requiring large amounts of energy. ... Isomerization is a mildly exothermic reaction and leads to the increase of an octane number.
What is a reforming reaction?
Reforming reactions are widely used to produce hydrogen from hydrocarbons and alcohols. Steam reforming involves the reaction between a hydrocarbon or alcohol and steam to form syngas (see eqn [11]), a mixture of H2 and CO. Dry reforming involves reactions of hydrocarbons or alcohols and CO2 (see eqn [12]).
Why is reforming important?
Reforming is a process designed to increase the volume of gasoline that can be produced from a barrel of crude oil. ... The octane rating of reformate is important because it affects the octane rating of the gasoline you buy at the pump.
What is platforming process?
A catalytic reforming process used to convert straight-chain aliphatic hydrocarbons into aromatic hydrocarbons and hydrogen using a platinum catalyst.
What is a CCR unit?
Process Heating Solutions. Continuous Catalytic reforming (CCR) is a chemical process that converts petroleum refinery naphthas distilled from low-octane oil into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline.
What is the purpose of reforming in a refinery?
The purpose of the reformer is to upgrade heavy naphtha into a high-value gasoline blend stock by raising its octane. The primary product of the reformer is reformate. However, it also generates large amounts of hydrogen that can be used in the hydrotreaters and hydrocrackers.
Why is cracking of naphtha important?
cracking of naphtha. It is important to ensure that the feedstock does not crack to form carbon, which is normally formed at this temperature. This is avoided by passing the gaseous feedstock very quickly and at very low pressure through the pipes which run through the furnace.
