The catalytic decomposition of methanol (MeOH) over single and different bimetallic exchange combinations or cobalt (Co), chromium (Cr) and copper (Cu) and zeolite Beta (H-BEA) was studied using a fixed-bed catalytic reactor in
the temperature range 100"C-500.C, at MeOH feed concentration of 11,500 ppmv and gas hourly space velocity (GHSV)of 26,500 hour'1.
