Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content called coke. Coke consists almost entirely of hydrocarbons. The porosity gives it a high surface area, … See more “Coking is a refinery unit operation that upgrades material called bottoms from the atmospheric or vacuum distillation column into higher-value products and produces petroleum coke—a coal-like material.”. In heterogeneous catalysis See more • Gas to liquids See more WebThe renewable naphtha has a low coking tendency, and long run lengths can be expected. The results obtained in this study are scaled-up to industrial furnaces (Lummus SRT-VI, Millisecond, USC Shaw Stone&Webster) using COILSIM1D8,9, resulting in product yields and run lengths for a typical range of industrial operating conditions.
