Electrically Heated Stack-like Reactor

3 Methanol Steam Reforming 3 [MSR 3] Electrically Heated Stack-like Reactor 

Numerical calculations revealed that isothermal operation was feasible throughout a catalyst layer as thick as 60 pm in a micro structured reactor under the conditions 

The catalyst (Pd/ZnO) was introduced by wash coating prior to the mounting, which was performed by electron beam welding. Calcination and reduction of the catalyst were performed after the welding procedure. The total heating power of the six heating cartridges was 1.5 kW. Bores were introduced for temperature determination at various positions. The feed inlet temperature was set to 140 °C. 

At 310 °C reaction temperature, a pressure of 1.25 bar and an S/C ratio of 1.9, 80% methanol conversion was achieved in the stainless-steel reactors compared with 90% for the copper reactor. The carbon monoxide concentration determined in the reformate was 0.5 vol.%. Lower temperature gradients were found for the copper reactor (7 K) than the stainless-steel device (18 K). Non-stationary measurements were carried out at the reformer reactors. The reaction followed the
