To explore the desulfurization mechanism of petcoke during high-temperature pyrolysis, TG-MS was used to analyze and identify the sulfur-containing gases released during pyrolysis. Fig. 3 shows the TG and dTG data of Qingdao petcoke from 298 to 1673 K over 147.5 min (faster due to equipment limitations). The TG and dTG curves showed …
Figure 1. Rotary kiln calciner & coke bed loading in kiln A shaft calciner has multiple vertical refractory shafts surrounded by flue walls. The green coke is fed into the top and travels down through the shafts and exits through a water cooled jacket at the bottom, Figure 2. The movement of coke is controlled by opening
Calcined coke is the best material for making carbon anodes for smelting of alumina to aluminum. Petroleum coke is usually calcined in a gas-fired rotary kiln or rotary hearth at high temperatures, around 1200 to 1450 °C, to remove moisture, drive off volatile matters, increase the density of the coke, increase physical strength, and electrical conductivity …
Calcined petroleum coke (CPC) is created from green petroleum coke (GPC), a by-product of refining crude oil. While CPC can be created using a number of processes -- including rotary kiln, hearth and vertical shaft technologies -- the high-temperature conversion from green coke to calcined coke alters the material in key three ways:

In this work, advanced burden distribution concepts were introduced into the calcination process of petroleum coke in a vertical shaft calciner. Experimental devices were established to determine the resistance characteristics of a petroleum coke particle packed bed, along with a cold physical model of a 1/8 scale vertical shaft calciner.
Vertical Kilns Vertical Shaft Kiln Structures & Working Principles. In cement plants using vertical kilns, the grinded raw materials are first made into wet pellets by adding 12-14% water to the pelletizing pan of the disc pelletizer.Then the wet pellets are fed from the kiln top and discharged from the bottom after calcination.
