Production of catalysts or catalyst additives comprises kneading and/or grinding, spray drying and heat treating a catalytically active component, preferably H-ZSM-5 zeolite, and aluminium hydroxide and/or aluminium hydroxy compound(s) and/or other binders and optionally kaolin(ite)- and even slurry containing liquefiers. The novelty is that instead of using kaolin(ite) as filler, silicic acid modifications of formula H4+y-zÄ(SiO4/2)x-y(AlO4/2)y(SiO3/2O)4-z (AlO3/2)zÜ (I) (where y<1; z<1; and x=0, 4, 10 or 16-18) are partially used.
