hüdrokrakkimisel
Hüdrokrakkimisel is a chemical process used in petroleum refining to break down heavy hydrocarbon molecules into lighter, more valuable ones. This process is a type of catalytic cracking, meaning it uses a catalyst to speed up the reaction and improve efficiency. The "hydro" in hüdrokrakkimisel refers to the presence of hydrogen during the cracking process. This hydrogen helps to saturate the free radicals formed during cracking, which in turn reduces the formation of coke, a carbonaceous deposit that can foul the catalyst and equipment.
The process typically involves heating heavy petroleum fractions, such as gas oil or vacuum residue, to high
