Question

What is the classification of crude oil?

Answer 1

Classification of crude The hydrocarbons found in petroleum are classified into the following types:[19,20]Paraffins(CnH2n+2)saturated hydrocarbons with straight or branched chains, but without any ring structure.Cycloparaffins (CnH2n)(naphthenes),saturated hydrocarbons containing one or more rings, each of which may have one or more paraffin side-chains(also known as alicyclic hydrocarbons).Aromatics(CnH2n-6)i.e,hydrocarbons containing one or more aromatic nuclei such as benzene, naphthalene, and phenanthrene ring systems that may be linked up with (substituted) naphthalene rings or paraffin side-chains. Paraffins:Carbon atoms connected by single bondOther bonds saturated with hydrogen Naphthenes:Ringed Paraffins (Cycloparaffins)All bonds saturated with hydrogen Aromatics:Six Carbon Rings (Multiple Bonding)All bonds unsaturated Olefins:Usually not in crude oilFormed During ProcessingAt least two carbon atoms connected by double bond
