The FAST setup is capable of conducting steam cracking reactions and coke measurements through both offline and online methods. In the online approach, a coupon is suspended in the reactor and coke formed during reaction is monitored over time to measure catalytic and asymptotic coking rates. During offline coke measurement analysis, the coke formed on the inner wall of the reactor tube during steam cracking reactions is burnt and the combustion gases are measured using Infrared spectroscopy (IR), correlating the results to the mass of the formed coke. Additionally, during experiments, the effluent products of steam cracking are analysed online using a Refinery Gas Analyzer (RGA) and GC×GC. The feedstocks utilized in FAST are liquids, with the operating pressure and temperature set at 1.8 bar and 900-1050°C, respectively.
