Abstract
A method of cracking a hydrocarbon composition having a normal boiling range beginning at a temperature of at least about 200° C., includes the steps of providing the hydrocarbon composition in a reactor including a first electrode mechanism, a second electrode mechanism and at least one layer of a normally solid dielectric material positioned between the first and the second electrode mechanisms. The hydrocarbon composition within the reactor is exposed to a dielectric barrier discharge, and the dielectric barrier discharge is controlled to convert the hydrocarbon composition into products having normal boiling points of below about 200° C.
