Hydrocarbon Analyzer Operating Principle

The sample was burned in an oxygen stream at 850°C in the presence of a catalyst. The water produced by the hydrogen combustion in the sample is absorbed and electrolyzed by the Pt-P2O5 electrolytic cell; the water produced by the carbon dioxide generated by the combustion of the carbon in the sample reacts with lithium hydroxide at a certain temperature and is absorbed by another Pt-P2O5 electrolytic cell and electrolyzed. . According to the amount of electricity consumed by the electrolyzed water, the hydrogen and carbon contents of the sample are calculated according to Faraday's law of electrolysis. The interference of sulfur and chlorine in the sample on the carbon measurement was removed from the pyrolysis product of silver permanganate in the combustion tube, and the interference of the nitrogen oxides on the carbon determination was removed by the particulate manganese dioxide.

The hydrocarbon analyzer uses a controlled current coulometric analysis method. The water generated by the reaction is carried into the Pt-P2O5 electrolytic cell by the carrier gas (oxygen) and reacts with P2O5 to form metaphosphoric acid. The partial electrolysis of the phosphoric acid is terminated when the electrolytic current is reduced to the end current. electrolysis. A single-chip microcomputer integrates the electricity consumed in the electrolysis process and converts the integrated value of the electricity in real time into the mass of hydrogen and carbon (milligrams). The percentage of carbon and hydrogen is finally displayed and the measurement result is calculated as air. Dry base and dry base forms are printed. When there is no air drying base moisture data, the total hydrogen value and the air dry base carbon value are printed.
