Furfural, purified over calcium oxide CaO, and freshly distilled, is used for decarbonylation. The reaction products are analyzed on an LHM-8MD chromatograph. Catalyst activity is expressed in percent of furfural conversion per pass, selectivity (%) in terms of furan yield from converted furfural, catalyst stability — in terms of the time of decarbonylation of furfural.
