WebReforming is a process designed to increase the volume of gasoline that can be produced from a barrel of crude oil. Hydrocarbons in the naphtha stream have roughly the same number of carbon atoms as those in gasoline, but their structure is generally more complex. What is the purpose of reforming in a refinery? WebReforming uses heat and pressure to convert unbranched fractions into cycloalkanes (e.g. cyclohexane) and arenes (e.g. benzene). These products are used in petrol and as a feedstock for a wide range of organic chemicals including many pharmaceuticals and dyes.After studying this section you should be able to:
