One-step heat treatment to process semi-coke …

2018-12-10 · Nevertheless, semi-coke powders with sizes smaller than 3 mm generally cannot be used in metallurgical industries and are abandoned as solid waste, resulting in environmental contamination. Herein, boron doping followed by facile one-step heat treatment in the range of 2100 to 2700 °C has been carried out to process semi-coke powder waste.

Modeling reaction kinetics of petroleum coke …

Kinetics characteristics of petroleum coke gasifiion with CO 2 at 1248–1323 K and 0.1 MPa were studied using a pressurized thermogravimetric analyzer (TGA). It is shown that gasifiion rate increases with increasing conversion and then decreases after reaching a peak value around x = 0.3.The poor initial porosity is the main reason of the occurrence of maximal gasifiion rate.
