Sep 24, 2011· Because of low pressure & high temp of coking process (+950 C/1472 F) most of the VCM in green petroleum coke is mostly resid with some lighter components removed. There was fairly good review of petcoke by API group for EPA which looked at petroleum coke for both Qualitative and Hazard focus for EPA on both green and calacined petcoke.
occasions, 100 percent petroleum coke or combinations of coal and petroleum coke replace coal. In other occasions, other combustible materials such as tires, rice husks, liquid or solid waste fuels replace or partially replace the main fuels as well. This paper focuses only on fuel changes to coal, petroleum coke and combinations of both.

The vibrated bulk density (VBD) is one of the most important calcined coke properties. In the context of changing green coke quality, a reliable forecast of the calcined coke VBD from small samples of green coke is required. To a certain extent, the VBD can be predicted from green coke properties, such as the Hardgrove Grindability Index (HGI ...
