Coke Strength after Reaction (CSR) refers to coke "hot" strength, generally a quality reference in a simulated reaction condition in an industrial blast furnace.The test is based on a procedure developed by Nippon Steel Corp in the 1970s as an attempt to get an indication of coke performance and is used widely throughout the world since then.
Micro carbon residue, commonly known as "MCR" is a laboratory test used to determine the amount of carbonaceous residue formed after evaporation and pyrolysis of petroleum materials under certain conditions. The test is used to provide some indication of a material's coke-forming tendencies.
Conradson carbon residue, commonly known as "Concarbon" or "CCR", is a laboratory test used to provide an indication of the coke-forming tendencies of an oil. Quantitatively, the test measures the amount of carbonaceous residue remaining after the oil's evaporation and pyrolysis .
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

3 C 2 H 4 → 2 C ("coke") + 2 C 2 H 6. A more realistic but complex view involves the alkylation of an aromatic ring of a coke nucleus. Acidic catalysts are thus especially prone to coking because they are effective at generating carbocations (i.e., alkylating agents). [3] Coking is one of several mechanisms for the deactivation of a ...

In an oven, air is passed through a bed of coke. The initially produced CO 2 equilibrates with the remaining hot carbon to give CO. [65] The reaction of CO 2 with carbon to give CO is described as the Boudouard reaction. [66] Above 800 °C, CO is the predominant product: CO 2 (g) + C (s) → 2 CO (g) (ΔH r = 170 kJ/mol)
