Also known as petroleum coke, petcoke is produced through the refining of petroleum and contains a high proportion of carbon. It is a form of solid carbon produced by means of heat decomposition and polymerization of heavy liquid hydrocarbons derived from the refining of crude. There are many commercial varieties of petcoke with different physical and chemical characteristics being used in different industrial applications, depending on the method of industrial production used to obtain it. The most common production methods used are:

  1. Green delayed coking, a method of cracking in which the carbonization reactions involve dehydrogenization, restructuring and polymerization. The working temperature fluctuates between 480ºC and 500ºC and a complete production cycle takes at least 16 hours.
  2. Fluid coking is a continuous process of pulverization at high temperatures on a fluid surface in which the coke particles are maintained at a pressure of between 20-40 psi and 500ºC. These feed vapors are subjected to heat cracking while they are being deposited, forming a liquid film on reheated coke particles, finally becoming nucleant agents. Thus, the particles grow in layers until they can finally be removed. Finally, another layer of nucleant coke particles is added to the system.
