Motor fuel alkylation in the petroleum refining industry refers to the acid-catalyzed conversion of C 3 -C 5 olefins with isobutane into highly branched C5-C12 isoparaffins collectively called alkylate, a valuable gasoline blending component. Alkylation reactions are catalyzed by liquid and solid ...
In organic chemistry, alkylation is known as the addition or substitution of an alkyl group to an aromatic ring, such as via the well-known Friedel Crafts alkylation reaction. In terms of petroleum refining, alkylation refers to the combination of a small olefin with a small isoparaffin, ...

Isobutane/1-butene alkylation is an important acid catalyzed reaction process being developed by the petroleum refining industry for the production of environmental benign gasoline. The resulting alkylate production predominantly contains isoparaffin, especially isooctane. It is considered to be an ideal blen...

increase in octane value. Conversion of light FCC naphtha olefins also leads to substantial reduction of gasoline olefin content and vapor pressure. The yield-octane uplift of MBR makes it one of the few gasoline reformulation processes that is actually economically beneficial in petroleum refining. ...
The production of higher molecular weight isoparaffins, having valuable antiknock properties as motor fuel is of considerable importance in the petroleum refining industry. This is particularly true in recent times due to the progressive restrictions which are being placed upon the use of leadcontaining...
