Methyl-isobutyl –ketone (MIBK) was obtained in vapor phase, from acetone andhydrogen in a single step, using Pd/H-ZSM-5 as a catalyst. The experiments were performed in acontinuous fixed bed reactor at 5 atm, 170 oC, hydrogen/acetone molar ratio measured at reactoroutlet (MRHA) 0.4 and acetone WHSV 0.3 h-1. Acetone conversions up to 50 % and MIBKyield up to 45 % were obtained. The experimental data showed that the presence of zinc oxide,in an amorphous form, decrease the Pd/Zn- H-ZMS-5 catatalyst’s activity in the process ofreductive condensation of acetone. The selectivity for methyl-isobutyl ketone also presents adecrease when zinc in an amorphous form is added. This behavior is due probably to thedecrease in the activity of the acid catalyst centers in the presence of zinc oxide in an amorphousform. |
