The research of all kinds of factors is put up on the inner coking of coal in the plasma reactor during the processing of pyrolysis of coal to acetylene, includ cooking phenomenon, coal of property, coal of grain degree, enter anticipate a speed , power and equip structure. In the arc plasma jet, different kind of coal has different coking character. The aromatics, colloids, asphaltene and carbenes are the precursors of the cokes.The mostly reasons of coking in the plasma reaction equipment are the particle size, the feeding velocity, the power of plasma and the structure of equipment. With the increasing of feeding velocity, the coking of system becomes worse. When the particle size is less than 80~100 mesh, the system will not produce cokes. When the particle size is about 100~120 mesh, the system will begin to produce cokes. When the particle size is larger than 140 mesh, the system will produce a lot of cokes.With the increasing of plasma power, the speed of coking will become smaller. |
