Reformer monolithic autothermal methanol

Homg described the start-up behaviour of their monolithic autothermal methanol reformer [479]. The ceramic monolith was coated with a mixed platinum and copper/ zinc oxide catalyst. The monolith had 117-mm diameter and 50-mm length, while the whole reactor was more than 510-mm long. Glow plugs were used for the start-up.

Comparison Between Coated Micro Structures and a Conventional Monolith Applied to Autothermal Methanol Reforming... 

Chen et al. [36] performed a comparison of micro structured steel and aluminum plates with a conventional monolith by varying the GHSV. Full conversion could be maintained for autothermal methanol reforming in the micro structures up to a GHSV of 40 000h 1, whereas conversion dropped to 80% at 20 000h 1 at the monolith. Even at 186 000 h, still 95% conversion could be achieved in the stainless-steel micro reactor. No significant performance differences were observed between the steel and aluminum plates.
