2014/5/31· Later processes, designed to raise the yield of gasoline from crude oil, split higher-molecular-weight constituents into lower- molecular-weight products by processes known as cracking. The needs of the petroleum industry in studies dedied to trace metals determination are highly related to exploration, but also to exploitation activities for corrective actions during oil production and

Co-Processing of Green Crude in Existing Petroleum Refineries
Fluid alytic Cracking: converts high molecular weight gasoils to gasoline, distillate and petrochemical feedstock in the petroleum coke • Petroleum coke yield is about 20 to 30 wt% of feed and is essentially solid carbon • Cokers produce sponge fuel grade
Cracking Meaning | Types of Cracking - Thermal Cracking …
The complex high molecular weight organic compounds are generally long chained hydrocarbons such as petroleum. This process is used extensively in the petroleum industry for the commercial preparation of low molecular weight hydrocarbon fuels such as gasoline and diesel from high molecular weight long chain hydrocarbons and kerogens.
