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 to afford a conversion product comprising aromatic compounds; b) recovering the aromatic compounds from said conversion product; c) separating a higher molecular weight fraction comprising polyaromatic hydrocarbons (PAH) from a lower molecular weight fraction comprising benzene, toluene and xylene (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 to obtain lower molecular weight aromatics (BTX).

Biomass is converted into a bio-oil containing stream in a riser reactor containing a cooling media. The cooling media quenches the rapid heat transfer to the biomass during cracking of the biomass in the mixing zone of the riser. By lowering the temperature to which the mixing zone effluent is exposed, production of carbon monoxide and light gases is decreased during thermolysis of the biomass.
