       MeOH is decomposed by heat into trioxymethylene, a decomposition facilitated by Zn, but Fe causes a further decomposition into H2 and CO.  In presence of graphite, MeOH yields considerable quantities of CH4.  When MeOH is passed through a red-hot Fe tube, considerable quantities of HCHO are produced together with combustible gases and about 3% of C.  The oxides of Zn, Fe and Cr are classified as dehydrogenation catalysts.
