Issue 25/2013 - Pioneering new ways to clean coal utilization

Recently, the plasma coal-to-acetylene technology independently developed by Xinjiang Tianye has obtained 5 national invention patents, and its core process and device have formed a technical patent group
.
After the project was included in the national science and technology support plan in 2013, the technology research and development team optimized and improved the service life of the core equipment, so that the continuous and stable operation time of the plasma torch exceeded 200 hours
.
The project team has sharpened its sword for thirteen years, made full use of its own advantages and mobilized the technical resources of related industries through independent innovation and cooperation with famous research at home and abroad, and finally opened up a new way of
clean utilization of coal.

Plasma cracking coal to acetylene is with the help of hydrogen plasma high temperature, strong chemical activity and coal and acetylene close to the hydrocarbon ratio and other characteristics, coal powder directly sprayed into the temperature above 3500 °C plasma rapid cracking, at 1500 °C high temperature quickly reached chemical equilibrium, the formation of acetylene, hydrogen as the main pyrolysis gas, and then after gas separation and concentration, to obtain high-purity acetylene
.
This technology has the advantages of low carbon, low resource consumption, low pollution, short process, clean and efficient, and has great prospects
in the field of clean coal utilization.
