n: a process for manufacturing components for 100-octane gasoline. An alkyl group is introduced into an organic compound either with or without a catalyst. Now usually used to mean alkylation of isobutane with propene, butenes, or hexenes in d1e presence of concentrated sulphuric acid or anhydrous hydrofluoric acid.

a reverse cracking process that convents hydrocarbon light ends (olefins) into longer chain, liquid fuels.

n: see butylene

n: hydrocarbon member of the olefin series, with the chemical formula C4H8. Its official name is butene.

n: in petroleum refining, the process of altering the arrangement of the atoms in the molecule without adding or removing anything from the original material. Straight-chain hydrocarbons are converted to branched-chain hydrocarbons with a substantially higher octane rating in the presence of a catalyst at moderate temperatures and pressures. The process is basic to the conversion of normal butene into isobutane.
