It can be seen from Table 1, compared with sulfur content of petroleum coke before calcination, low sulfur coke has the minimum sulfur emissions, and an average of it is about 6%. At the range of 700–900 °C, sulfur emission is relatively concentrated, but sulfur emission is very small at 1000–1100 °C and that indicates most of the sulfur ...
