Apparatus for purification of raw gasoline from catalytic cracking

Catalyst based on a molecular sieve and a process for selective hydroisomerisation of long linear and/or slightly branched paraffins using that catalyst

A process and apparatus for treating raw gasoline from catalytic cracking to obtain gasoline with the qualities required for use as motor fuel comprises selective hydrogenation followed by stabilization and optional cooling of the effluent, then sweetening followed by degassing to obtain a dedienized, stabilized and sweetened gasoline. The hydrogenation catalyst preferably comprises 0.1-1% of palladium deposited on a support, sweetening is preferably carried out on a solid catalyst containing an aluminosilicate of an alkali metal (for example sodalite), a metal chelate and activated charcoal. The product from this process can be placed directly in the gasoline pool or, advantageously, fractionated to obtain one or more cuts which can be used as feeds for etherification.

Process for purification of raw gasoline from catalytic cracking

Process for the acylation of aromatic ethers

Catalytic cracking gaseolines are treated by: (a) fractionating the raw gasoline cut into two cuts; (b) optional selective diene hydrodenation of the light cut, then mild hydrotreatment and stripping; (c) sweetening the light cut which is conducted before the mild hydrotreatment step by contact with a supported catalyst containing 0.1-1% by weight of palladium, or after the mild hydrotreatment step and which is then an extractive sweetening step, or with a catalyst having an alkaline base optionally incorporated and also an oxidizing agent. The heavy gaseoline fraction is optionally desilphurized in a hydrotreatment unit. The desulpurized and sweetened light gaesoline can be added to the gasoline pool either directly or mixed with the desulphurized heavy gaseoline cut.
