Zusammenfassung:The invention provides a method and a device for measuring sulfur content distribution in a coking product, and belongs to the technical field of coking coal detection. The method comprises the following steps: respectively collecting coking products including a solid-phase product coke, a gas-phase product coal gas and a liquid-phase product coal tar by using a collecting device, and measuring the sulfur content in the coal gas by using a gas chromatographic method; measuring the content of sulfur in the feed coal and the solid-phase product by adopting coulometric titration; and determining the sulfur content in the liquid-phase product by adopting a subtraction method, namely determining the total sulfur content of the pyrolysis coal according to the use amount and the sulfur content of the feed coal, and subtracting the sulfur contents in the gas-phase product and the solid-phase product from the total sulfur content to determine the sulfur content in the liquid-phase product. By utilizing the method, the
