Residues (petroleum), catalytic reformer fractionator (10C)
Residues, petroleum, catalytic reformer fractionator
A complex combination of hydrocarbons produced as the residual fraction from distillation of the product from a catalytic reforming process.  It consists of predominantly aromatic hydrocarbons having carbon numbers predominantly in the range of C10 through C25 and boiling in the range of approximately 160.degree.C to 400.degree.C (320.degree.F to 752.degree.F).  This stream is likely to contain 5 wt. % or more of 4- or 6-membered condensed ring aromatic hydrocarbons.
