(materials)

A product of polymerization of normally gaseous hydrocarbons to form high-octane liquid hydrocarbons boiling in the gasoline range.

Polymer Gasoline

polymer distillate, a high-octane component of fuels for piston engines with spark ignition.

Polymer gasoline is produced by catalytic polymerization of the propane-propylene and butylene fractions of gases from petroleum cracking and reforming. The onset of boiling for polymer gasoline is not below 70°C, and the termination of boiling is not above 225°C. The content of unsaturated hydrocarbons is 20–90 percent, with a relatively low content of paraffin, naphthene and, in particular, aromatic hydrocarbons. The octane number of hydrogenated polymer gasoline with 3.3 g tetraethyl lead per kilogram is not less than 104. Inhibitors (antioxidants) are added to stabilize polymer gasolines and commercial fuels containing this component.
