1. A process for the preparation of aromatic compounds from a feed stream containing biomass or mixtures of biomass, the process comprising:
a) subjecting a feed stream containing biomass or mixtures of biomass to a process comprising catalytic pyrolysis to afford a conversion product comprising aromatic compounds comprising a higher molecular weight fraction comprising polyaromatic hydrocarbons (PAH) and a lower molecular weight fraction comprising benzyne, toluene and xylene (BTX);
b) recovering the aromatic compounds from said conversion product;
c) separating said higher molecular weight fraction comprising PAH from said lower molecular weight fraction comprising BTX by distillation;
d) reducing at least part of said higher molecular weight fraction to obtain a reduced fraction comprising polycyclic aliphatics (PCA); and
e) subjecting the higher molecular weight fraction obtained in step c), the reduced fraction obtained in step d), or a mixture thereof, to a process comprising catalytic pyrolysis to obtain lower molecular weight aromatics (BTX).
