Which catalyst is used in reforming of naphtha?
Naphtha reforming catalyst is a bifunctional catalyst consists of a metal function, mainly platinum, and an acid function, usually chloride alumina. The metal function catalyzes the hydrogenation and dehydrogenation reactions and the acid function promote the isomerization and cyclization reactions [11], [12], [13].
How is naphtha produced?
Shale naphtha is obtained by the distillation of oil produced from bituminous shale by destructive distillation. Petroleum naphtha is a name used primarily in the United States for petroleum distillate containing principally aliphatic hydrocarbons and boiling higher than gasoline and lower than kerosene.
Which catalyst is used for platforming process?
Platforming is herein defined as a catalytic reforming process in which a hydrocarbon fraction containing naphthenes and paraffins and boiling in the gasoline boiling range is contacted in the vapor phase and in the presence of a substantial pressure of hydrogen with a catalyst containing platinum on a suitable support …
What is reforming of petroleum Why is reforming done?
Reforming is a process designed to increase the volume of gasoline that can be produced from a barrel of crude oil. By controlling the temperature and flow rate of the reformer, refinery operators can increase the octane rating of the reformate, but that also has the effect of producing less reformate.
What is naphtha solvent?
Naphtha is a petroleum solvent similar to mineral spirits but with a greater volatility; it is used chiefly as a paint thinner or a cleaning agent. Naphtha is a more powerful solvent than mineral spirits, so less is needed to thin the same amount of paint.
What are some possible starting materials to refine to create naphtha?
Naphtha (/ˈnæpθə/ or /ˈnæfθə/) is a flammable liquid hydrocarbon mixture. Mixtures labelled naphtha have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat. In different industries and regions naphtha may also be crude oil or refined products such as kerosene.
What is the process of catalytic reforming?
Catalytic reforming is a process used to convert low-octane naphthas into high-octane gasoline blending components called reformates. Reforming is the total effect of several reactions that occur simultaneously including cracking, polymerization, dehydrogenation, and isomerization.
What is catalytic reforming and isomerization?
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.
