Korte beschrijving

Nowadays, steam cracking of hydrocarbons is still one of the most vital chemical processes for the production of many key-building blocks of the chemical industry. In steam cracking, feedstocks, ranging from ethane and propane over LPG and naphtha to light gasoil, are converted in a high temperature process to ethylene, propylene and several other valuable components. To date, almost 200 million tons of ethylene are manufactured globally per year, underlining the process significance. The formation of carbonaceous deposits on the inner wall of the reactor forces industrial steam crackers to regularly interrupt production to remove the coke via combustion with a steam/air mixture. The reduction of coke formation is one of the most promising ways of further improving steam cracker efficiency. In an effort to mitigate coke formation several anti-coking technologies have been evolved over the years, namely 3-D reactor technologies, application of additives and use of advanced surface technologies. The focus of this PhD is put on the last two categories. Finding the optimal process conditions to operate and knowing the effect of extreme carburization and oxidation on a broad range of innovative commercially available materials constitutes its core.
