Abstract
A system and method including providing a feed having alkyl-bridged multi-aromatic compounds to a tubular reactor, heating the tubular reactor, and cleaving an alkyl bridge of the alkyl-bridged multi-aromatic compounds.
Claims12
A method of processing alkyl-bridged multi-aromatic compounds, comprising:
- providing a feed comprising an alkyl-bridged multi-aromatic compound to a coiled tubular reactor, the alkyl-bridged multi-aromatic compound comprising a first aromatic ring coupled via an alkyl bridge to a second aromatic ring, wherein the alkyl bridge comprises at least two carbons;
- heating the coiled tubular reactor;
- and
- cleaving the alkyl bridge in the coiled tubular reactor to separate the alkyl-bridged multi-aromatic compound into a first aromatic compound comprising the first aromatic ring and a second aromatic compound comprising the second aromatic ring.

A method of processing alkyl-bridged multi-aromatic compounds, comprising:
- feeding alkyl-bridged multi-aromatic compounds each comprising an alkyl bridge to a coiled tubular reactor;
- feeding hydrogen to the coiled tubular reactor;
- providing heat from a furnace to heat the coiled tubular reactor, wherein at least a portion of the coiled tubular reactor is disposed in the furnace;
- and
- performing hydrodearylation on the alkyl-bridged multi-aromatic compounds in the coiled tubular reactor via the hydrogen and via the heat provided by the furnace, the hydrodearylation comprising breaking a carbon-carbon bond of the alkyl bridge of at least some of the alkyl-bridged multi-aromatic compounds.
