【Q&A Question 082】March 23, 2018: Briefly explain the difference between the meanings of \"carbon formation\" and \"carbon deposition\" “\"Carbon formation\" can generally be understood as a thermodynamic process, referring to the reactions that occur during the conversion of light oil and result in the formation of carbon. On the other hand, \"carbon accumulation\" can be regarded as a kinetic outcome – it occurs when the overall rate of carbon formation exceeds the rate of carbon destruction, leading to an accumulation of carbon. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

Answer: “Carbon formation” can generally be understood as a thermodynamic process, referring to the reactions that occur during the conversion of light oil and result in the formation of carbon. On the other hand, “carbon accumulation” can be regarded as a kinetic outcome – it occurs when the overall rate of carbon formation exceeds the rate of carbon destruction, leading to an accumulation of carbon, which is what is meant by “carbon accumulation”.

“\"Coking\" can generally be understood as a thermodynamic process, referring to the reactions that result in the formation of carbon during the conversion of light oil. \"Carbon deposition\" can be understood as a dynamic outcome, referring to the accumulation of carbon that occurs when the overall rate of carbon formation reaction is greater than the rate of carbon removal reaction.

Carbon deposits accumulate on the surface of the catalyst, usually on the active sites； Coking generally covers the surface of the catalyst
