WebGasoline Petroleum is converted to useful products such as gasoline in three steps: distillation, cracking, and reforming. Recall from Chapter 1 that distillation separates compounds on the basis of their relative volatility, which is usually inversely proportional to their boiling points. WebCatalysts used for cracking. Typical catalyst used for this purpose is the mixture of silica (SiO 2) and alumina (Al 2 O 3). The mixture of these two substances give us aluminum silicates. Catalytical cracking produces gasoline of higher octane number. In this way the gasoline of better quality is obtained. Steam cracking

Fluid Catalytic Cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, olefinic gases, and other petroleum products. The cracking of petroleum hydrocarbons was originally done by thermal cracking, now virtually replaced by catalytic cracking, which yields greater volumes of high octane rating gasoline; and produces by-product gases, with more carbo… WebJul 24, 2024 · Cracking is the number one process for the commercial production of gasoline. In 1913, thermal cracking was invented by William Meriam Burton, a process that employed heat and high pressures. …
WebFeb 27, 2024 · Hydrocracking is a catalytic chemical process used in petroleum refineries for converting the high-boiling hydrocarbons in petroleum to low-boiling products such as gasoline, kerosene, jet fuel and diesel oil.
