Green petroleum coke, a form of industrial waste produced in the oil-refining process, was used to synthesize nitrogen-doped graphene-like plates (N-GLPs) together with melamine. In this study, characterization and batch experiments were performed to elucidate the interaction mechanism of N-GLPs and bisphenol A (BPA). Structural analysis of N-GLPs, including scanning electron microscopy …
Needle coke, as an important carbon material, can be classified into two types, i.e., petroleum-based needle coke  with heavy oil as the raw materials, and coal-based needle coke  with coal

2019/7/15· The reaction characteristics of petroleum coke are unique and different from coal and biomass, although the CO 2 concentration increased in the presence of oxygen carrier no matter what fuel is used. Guo [ 11 ] evaluated the CLG performance of Beisu bituminous coal based on Fe 2 O 3 and found the CO 2 concentration had two s, but the second one was much lower than the first one.
Petroleum coke–coal slurry (PCCS) was prepared by blending sub‐bituminous coal with petroleum coke in different proportions. The rheology and stability of PCCS were studied, and the mechanism
Petroleum Coke - an overview | ScienceDirect … A. A Boateng, in Rotary Kilns (Second Edition), 2016. Abstract. Petroleum coke is a by-product of the coker process in the oil industry. In its raw form, it is also called "green coke" or green petroleum coke.
Every coal does not possess all the desired specific properties and composition strictly required for making quality coke for the blast furnace. India owes a vast reserve of coal to the tune of over 301 billion tonnes out of which only 12.67% are coking coal
2020/7/14· Deposits from coal-petroleum coke blends of 100:0, 90:10, and 80:20 on a coal:coke weight basis were generated under fouling and slagging conditions. Measurements of fouling deposit growth rates and slag deposit compressive strengths indie that petroleum coke blending with PRB subbituminous coal impedes the rate of ash deposition but promotes slag deposit strength.
