Abstract:
1. In a pyrolysis process in which a known amount of a hydrocarbon feed containing a known amount of an inert gas tracer, a hydrocarbon feed carbon content and a hydrocarbon feed hydrogen content, is charged to a pyrolysis furnace operated under pyrolysis cracking process conditions to yield a pyrolysis product wherein said pyrolysis product comprises a liquid fraction and a gas fraction, wherein said liquid fraction comprises a liquid fraction hydrogen content and a liquid fraction carbon content to thereby provide a liquid fraction hydrogen-to-carbon ratio, and wherein said gas fraction comprises a gas fraction inert gas tracer concentration, a gas fraction hydrogen content and a gas fraction carbon content, a method is provided for determining said liquid fraction hydrogen-to-carbon ratio, said method comprising the steps of: (a) determining said hydrocarbon feed hydrogen content and said hydrocarbon feed carbon content; (b) determining said gas fraction hydrogen content and said gas fraction carbon content by (c) determining said liquid fraction hydrogen-to-carbon ratio by
