hüdrocracking
Hydrocracking is a petroleum refining process used to convert heavy hydrocarbon fractions into lighter, more valuable products. It involves subjecting these heavy feedstocks to high temperatures and pressures in the presence of hydrogen gas and a catalyst. The hydrogen reacts with the hydrocarbon molecules, breaking them down into smaller ones and saturating any double or triple bonds. This process is crucial for maximizing the yield of gasoline, diesel fuel, and jet fuel from crude oil.
The feedstocks for hydrocracking are typically heavier distillates like vacuum gas oil, coker gas oil, and
Hydrocracking catalysts are typically bifunctional, possessing both acidic sites for cracking and hydrogenation/dehydrogenation sites for promoting
