  • Method Principle
    Under the condition of alumina as catalyst and loosening agent, a certain amount of coal or coke samples were injected into steam at 1050 C. All nitrogen and its compounds in the samples were reduced to ammonia. The ammonia is distilled by sodium hydroxide solution and titrated by saturated boric acid solution. The nitrogen content is calculated according to the consumption of standard sulfuric acid solution.
  • Basic parameters
    (1) Measurement range: 0.01-50%
    (2) The sample size is about 100 mg.
    (3) Single determination time: about 35 minutes;
    (4) rated power consumption: 4000W
