An extensive experimental program has been carried out in a pilot unit for the thermal cracking of hydrocarbons. On the basis of the experimental information and the insight in the mechanisms for coke formation in pyrolysis reactors, a mathematical model describing the coke formation has been derived...
The invention relates to a combination of compounds and a process using such combination useful for reducing or preventing coke formation in thermal cracking furnaces such as ethylene steam crackers. The combination is comprised of one o... MJ Lindstrom - EP 被引量: 20发表: 2002年 Coking of ...

Coke formation in fluid catalytic cracking (FCC) can markedly affect a unit’s performance and for over fifty years, it has been the subject of much investigation. [1–3]. Coke can arise from a number of sources, namely acid catalysed, metals mediated and pure thermal reactions. Therefore,...
Method for retarding corrosion and coke formation and deposition during pyrolytic hydrocarbon processingPatentsCorrosionThe present invention is directed to a method of reducing fouling and corrosion in furnaces during the thermal cracking of hydrocarbons. The method generally comprises adding to the ...
Modeling of catalytic coke formation in thermal cracking reactors At the start-up period, the most important mechanism in the coke production with a clean reactor surface is the catalytic mechanism. The study of this mech... A Mohamadalizadeh,J Towfighi,R Karimzadeh - 《Journal of Analytical ...
By employing a comprehensive time-sequential analysis approach to the continuous thermal reaction process of Gudao vacuum residuum, it has been found that there appear three categories of in-situ generated neophases with different morphologies, onset points and bulk effects before coke formation. These...

The reactions of the diolefins with other molecules also added to the coke formation. Hydrotreating the feed removes a lot of the coke precursors and greatly reduces coking issues. Coking in resid cracking In the 1970s and 1980s, resid cracking was introduced as a method of disposing of an ...
