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.
