FIGURE A: schematic diagram of technological apparatus for catalytic dehydrogenation of methanol; B: membrane reactor setup
During the catalytic performance evaluation of the prepared CMNRs above, the following procedures were conducted: (1) The methanol liquid was pumped into the evaporator and evaporated at 120 ℃; (2) Methanol vapor was mixed with N2 from nitrogen vessel in evaporator and the mixture reactant gas was flowed downward the reactor; (3) The mixture gas was permeated through the CMNR installed in the reactor and methanol in the mixture was cracked to form anhydrous formaldehyde, hydrogen and possible by-product under varied temperatures; (4) The product vapors were condensed in condenser, while the product gases were collected and detected by GC. On the apparatus, several reactors could be set up in serials, as shown in Figure S3.
