Web19 jul. 2024 · Hydrocracking is one of the processes where real-time temperature monitoring is essential. In this two-stage chemical reaction, heavy gas oil is broken down (cracked) using a catalyst and high temperatures. The cracked hydrocarbons are then saturated or treated with hydrogen to produce useful products like diesel and jet fuel.
