Coking Resistance Of Alumina Forming Cast Austenitic Stainless Steels, Lizeth Nayibe Ortiz Reyes

Theses and Dissertations

Coking is the process of carbon deposition from a gas phase that is encountered in many reforming, cracking and other high temperature processes. Coking in certain petrochemical processes can lead to carbon build up causing reduced process efficiency, corrosive attack and degradation of the alloy. Steam cracking of hydrocarbons is one of the most important process for manufacturing many base chemicals such as ethene, propene and other. A major influence on the energy efficiency and economics is the formation of coke on the inner wall of the reactors. With the accumulation of coke on the walls, eventually metallurgic constraints of …
