pyrobitumen उदाहरण वाक्य

Although the archaic definition of pyrobitumen includes low-maturity solid bitumens such as albertite, a definition more closely linked to the formation and destruction of oil from kerogen would define pyrobitumen as having an H / C ratio less than 1.0.
From these descriptions and other pyrolysis studies, it becomes clear that the H / C ratio of 0.5 given by Peters corresponds to the end of such pyrolysis yield, even though the bitumen becomes insoluble, and therefore pyrobitumen, prior to that maturity.
