Delayed coking is a semi-batch cyclic process that thermally cracks a variety of residual oil feeds into light gases, naphtha, diesel, heavy gas oil and petroleum coke. The heart of delayed coking technology is the furnace, in which a mixture of oil and steam is superheated in a short residence time environment such that coking in the furnace tubes is avoided.
Table 1 Proximate and ultimate analysis results of the petroleum coke Full size table The dispersing agent used was sodium lignosulfonate at a concentration of 0.8 wt% of the air-dried pulverized petroleum coke, which could optimize the slurryability of PCWS (Gao et al. 2015 ).

Coal, Coke, Coustion Residues, Biomass and Refuse-Derived Fuels Analysis: Some of the testing services include proximate and ultimate analysis, calorific value determination, ash fusion and elemental analysis, including mercury. Petroleum Products
The results were investigated with ultimate analysis, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The models showed that organic sulfur, nitrogen, and oxygen in the coke were mainly in the forms of thiophene-containing polycyclic aromatic hydrocarbon, polycyclic aromatic hydrocarbons containing pyrrole or pyridine, and C═O or C–O–C, respectively.
Ultimate Analysis Chemical properties of coal represented in percentage of weight. Included are carbon, hydrogen, sulphur, oxygen, moisture and ash. Underground Mine A mine where coal is produced by tunneling into the earth to the coalbed, which is then mined with underground mining equipment such as cutting machines and continuous, longwall, and shortwall mining machines.
