Coke Formation on Pt–Sn/Al2O3 Catalyst for Propane Dehydrogenation
Industrial & Engineering Chemistry Research, 2018Catalyst deactivation by coking is one major problem for propane dehydrogenation (PDH). To develop catalysts with high resistance to coke, the analysis of coke becomes essential.

Model Study of Shaft Injection of Reformed Coke Oven Gas in a Blast Furnace
, 2020Reformed coke oven gas (RCOG), a hydrogen-rich gas, is a promising auxiliary fuel for ironmaking blast furnaces (BFs) for lowing the coke consumption and production cost.

The fissuration of semi-coke during coking
Fuel, 1986Abstract To establish a predition model for coking on a physicochemical basis the complex coking process should be subdivided into several sub-mechanisms 1,2 . One aspect of this pattern is the examination of the contraction behaviour of semi-coke, which will influence quality features such as lump-size and mechanical strength of the coke product ...

Simulation of coking in coke furnaces
Coke and Chemistry, 2011Computer simulation of the coking process in coke furnaces provides information regarding the yield and quality of the coking products as a function of the temperature and the yield of volatiles from the batch. The simulation includes calculation of the temperature in the heating channel from the nonsteady heat-conduction equation of the coal bed in ...

Effect of pressure on coke yield in delayed coking [PDF]
Chemistry and Technology of Fuels and Oils, 1982 This paper presents data on the effect of pressure, in a coking straight-run and secondary resids from West Siberian crudes, on the yield and quality of the coke that is obtained. Increasing the pressure has a very marked effect on the coke yield, increasing the gas yield, and reducing the relative amount of coker gas oil.

Microtexture and structure of semi-cokes and cokes
Fuel, 1986Abstract During carbonization, before the semi-coke stage, parallel local orientation of polyaromatic structures occurs (local molecular orientation or LMO). The oriented species are usually classified in decreasing order by the extent of optical isochromatic areas and are studied at molecular range by means of transmission electron microscopy.

I enjoyed reading Seth Lloyd's article "The digital universe" (November pp30–36), particularly since it agrees with my general suspicion that the concept of "information" is far more fundamental than our theories of nature currently concede.

Coking is a process for thermally cracking large molecules in residual oil feeds from atmospheric or vacuum distillation columns into shorter-chain lower-boiling molecules, leaving behind the excess carbon in the form of petroleum coke. Three types of coking process are delay coking, fluid coking and Flexicoking.
