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: a product consisting chiefly of normal butane and isobutane, produced at a gas processing plant. Also called mixed butane.

n: 1. a hydrocarbon of the paraffin series with the formula C4lO and having its carbon atoms branched. 2. in commercial transactions, a product meeting the GPA specification for commercial butane and, in addition, containing a minimum of95% liquid volume isobutane.

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.
