Abstract

Embodiments in the present disclosure describe a process for recovery of lighter mono-aromatic compounds from a stream containing alkyl bridged non-condensed alkyl multi-aromatic compounds by conversion to non-condensed alkyl mono-aromatic compounds. The process includes supplying, to a reactor, a hydrocarbon feedstock containing alkyl bridged non-condensed alkyl aromatic compounds and a hydrogen stream. The process further includes allowing the alkyl-bridged non-condensed alkyl multi-aromatic compounds to react with hydrogen in the presence of a suitable catalyst to produce alkyl mono-aromatic compounds. The process may include processing the alkyl mono-aromatic compounds to produce valuable products, such as para-xylene. Various other embodiments are disclosed and claimed.
