Hydrocracking
Hydrocracking is an important process in oil refineries that turns heavy oil products into more valuable, lighter fuels like gasoline, diesel, and jet fuel. Think of it like breaking down big building blocks into smaller, more useful pieces. This process uses hydrogen and special materials called catalysts, working under high pressure and temperature. When you see this term in resumes, it usually indicates experience with complex refinery operations. Similar processes include thermal cracking and fluid catalytic cracking, which are all part of the refinery's toolkit for converting oil into useful products.
