Effects of surface texture features of the delayed coke prepared form coal tar according to the pressure heat treatment |
| 초록 |
The change of delayed coke made from coal tar with pyrolysis temperature was researched. Various delayed cokes was prepared by pyrolysis of coal tar. We representatively manufactured three kind cokes and find out what condition each cokes prepare. One is the pitch cokes that is slightly starting circular isotropic shape on the surface. Another is the semi-cokes with a small amounts of beta-resin. And we made the needle cokes that is structurally shown by polarizing microscope. Each of the conditions is that, firstly, circular isotropic shape in the cokes started when was heat-treated at 400 oC for 1hr. and then disappeared at 400 oC from 3hr. Secondly, the semi-cokes including 5~15w% beta-resin content is obtained at 500 oC from 1hr to 2hr. Finally, needle coke having uniform directional anisotropy is manufactured when was heated at 500℃ for 3hr. |
