Fourier transformation near-infrared spectroscopy was performed to determine total sugars, reducing sugar, nicotine, total nitrogen and total chlorine in green tobacco leaves, and correlation models were established.

Based on the fault tree of the cooling water system in asphalt gas decontaminating for carbon calciner,quantified evaluating system of reliability of cooling water system is set up by using of quantified analysis theory of fault tree.

In asphalt gas decontaminating(by adopting electro-catching) for Carbon Calciner,the weight of cooling water system is the maximum in the atomization pour system.

By studying characteristics, merits and solving problems of the different nozzle and new spray equipment in asphalt gas decontaminating for carbon calciner, the research provides a basis for the industrial design of swirl nozzle.

As the main raw materials for producing the anode are petroleum coke and pitch, therefore large amount of pitch fume will be emitted from the baking process.

Electrostatic treatment technology of asphalt gas produced by baking furnace of carbon;

Design of dust and asphalt gas control in production workshop of carbon factory;

Purification of asphalt gas produced by baking furnace of carbon;

The result shows that there is rather significant difference between slow-ashing method and 30 min-ashing method for the younger bituminous,but the difference is below the permissible value in the same laboratory.
