Hydrocracking, gasoline

Hydrocracked gasoline Alkylate gasoline Relatively olefin-free, low aromatic cracked gasoline blendstock. Composed of C and C8branched hydrocarbons this is a high-octane-number blending stock with MON values ranging from approximately 87 to 95 and RON values from 94 to 100. 

Hydrocracking gasoline has inadequate octane. Rich in naphthenic structures, it provides an excellent reforming feed, but in this case adds to the production of aromatics which are likely to be excessive for the market. 

Hydrocracking is a major process for the production of diesel motor fuel catalytic cracking is its counterpart for the gasoline production. 

British Coal Corp. is developing a gasoline-from-coal process at a faciUty at Point of Ayr (Scotiand). This process involves treatment with Hquid recycle solvents, digestion at 450—500°C, filtration to separate unconverted residues, and separation into two fractions. The lighter fraction is mildly hydrotreated, and the heavier one is hydrocracked (56). 

Additional gasoline and diesel fuel can be produced through further refining, such as hydrocracking or catalytic cracking of the wax product.
