USE OF ISOTOPIC ANALYSIS FOR DETERMINATION OF AROMATIC HYDROCARBONS PRODUCED FROM METHANE

摘要

Benzene and xylene are described having a unique distribution of deuterium and 13C such that H(deuterium) for each of the benzene and xylene is less than-250 and H(l3C) for the benzene is greater than-36 and for xylene is less than-24, wherein H(deuterium) = (R'sample/R'standard-1) X 1000 where R'sample is the ratio of deuterium to hydrogen in the benzene/xylene; and R'standard is the ratio of the natural abundance of deuterium to the natural abundance of hydrogen; and wherein H(13C) = (R''sample/R''standard-1) X 1000 where R''sample is the ratio of 13C to 12C in the benzene/xylene; and R''standard, is the ratio of the natural abundance of 13C to the natural abundance of12C.
