US Patent for Production and use of a premium fuel …

A premium “fuel-grade” petroleum coke is produced by modifying petroleum coking technology. Coking process parameters are controlled to consistently produce petroleum coke within a predetermined range for volatile coustible material (VCM) content. The invention includes a process of producing a coke fuel, the method comprising steps: (a) obtaining a coke precursor material derived from

The function of a pH buffer or metal ion ligand are several. These functions will be illustrated using orthophosphate ion to illustrate. Phosphate buffers the pH, resulting in reaction mixtures that can develop strongly acidic, mildly acidic, essentially neutral, mildly basic, or …

Coke bed structure in a delayed coker

The porous structure of the coke bed in a delayed coking reactor is investigated in order to understand how flow channels are formed and how the cooling water distributes during the quench stage

OSHA Technical Manual (OTM) | Section IV: Chapter 2

2002-3-30 · When coke is moved as a slurry, oxygen depletion may occur within confined spaces such as storage silos, since wet carbon will adsorb oxygen. inspection, maintenance, and turnaround activities. (Note: coke produced from petroleum is a different product from that generated in the steel-industry coking process.) the primary function of

The influence of product COCO2 ratio on the ignition …

The role of the product CO CO 2 ratio in the ignition behaviour and the temperature history of petroleum coke particles burning in incipiently fluidized beds is examined. The results establish that this ratio not only influences the determination of kinetic parameters from such measurements, but also exerts a significant effect on the ignition delay and temperature for particles of sizes of

Structural features of Qingdao petroleum coke from …

Green petroleum coke (petcoke) is a byproduct of oil refining , with a high fixed carbon value and a low ash yield . It is used as a precursor for activated carbon , as anode materials in lithium ion batteries , within carbon anodes in the steel and the alumina [6,7] industries.
