Effect of minerals on coke formation - UBC Library …

Petroleum coke is defined as the toluene-insoluble carbonaceous solid which can form in a variety of petroleum processing units, particularly due to heating of residual oils with a high asphaltene content. Coke formation is the objective in some high temperature (500°C) processes such as delayed coking or fluid coking, but is undesirable in refineries or heavy oil upgrading processes, where

C | Free Full-Text | Porous (Swiss-Cheese) Graphite | …

Porous graphite was prepared without the use of template by rapidly heating the carbonization products from mixtures of anthracene, fluorene, and pyrene with a CO2 laser. Rapid CO2 laser heating at a rate of 1.8 × 106 °C/s vaporizes out the fluorene-pyrene derived pitch while annealing the anthracene coke. The resulting structure is that of graphite with 100 nm spherical pores.

Coke is a function of heat. Many years ago it was believed that oxygen had to be present for coking to occur, but testing has shown that this is not true. You can coke any petroleum product in an inert atmosphere as long as the temperature is high enough. The finest lubriing oil available will start to coke at 300° F (150° C).
