Measurement of carbon to hydrogen ratio in hydrocarbons

摘要

The ratio of carbon to hydrogen in hydrocarbon samples is determined using gas chromatography and atomic emission detection. Comparison of the carbon to hydrogen ratio from different samples allows for qualitative determination of relative hydrogen content. Establishing a carbon to hydrogen ratio for a reference sample allows a further quantitative determination of carbon to hydrogen ratio.

主权项

1. A method for characterizing the ratio of hydrogen to carbon in a sample, comprising:
separating a plurality of compounds in a first hydrocarbon sample using gas chromatography; measuring atomic emissions from carbon atoms and hydrogen atoms for one or more compounds from the first hydrocarbon sample; determining a first hydrogen to carbon peak area ratio based on the hydrogen peak area and carbon peak area for the one or more compounds from the first hydrocarbon sample; separating a plurality of compounds in a second hydrocarbon sample using gas chromatography; measuring atomic emissions from carbon atoms and hydrogen atoms for one or more compounds from the second hydrocarbon sample; determining a second hydrogen to carbon peak area ratio based on the hydrogen peak area and carbon peak area for the one or more compounds from the second hydrocarbon sample; and comparing the first hydrogen to carbon peak area ratio and the second hydrogen to carbon peak area ratio.
