The process includes supplying, to a reactor, a hydrocarbon feedstock containing alkyl bridged non-condensed alkyl aro- matic 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 [Continued on next page] WO 2018/152389 Al MIDEDIMOMOIDEIREEMOMMIMMOMEHOMEEN CA, CH, CL, CN, CO, CR, CU, CZ, DE, DJ, DK, DM, DO, DZ, EC, EE, EG, ES, FI, GB, GD, GE, GH, GM, GT, HN, HR, HU, ID, IL, IN, IR, IS, JO, JP, KE, KG, KH, KN, KP, KR, KW, KZ, LA, LC, LK, LR, LS, LU, LY, MA, MD, ME, MG, MK, MN, MW, MX, MY, MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SA, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
