    Thus the rate of coke formation should be roughly proportional to the asphaltene concentration of the fluid. An example of this well-established relation is given in Table 2, where for fixed coking conditions of 1-hour at 400 C, the coke yield is roughly proportional to asphaltene (or the MCR) content of the fluid.

    What is a Coke Oven? (with pictures) - Info Bloom

    In the coke-making process, treated coal is placed in the coke oven. Due to the high temperature inside, coal gas, coal water, and tar are separated from the coal. The gas and water then fuse together with carbon and the remainders of ash. The hard residue that remains at the end of this process is commonly referred to as coke
