Summary
The focus of our attention has now shifted to the effect of ammonia on hydrodeoxygenation (HDO) of selected model compounds. Scouting studies with 2-phenylphenol (OPP), phenyl ether (PE), 3-ethylphenol (MEP) and dibenzofuran (DBF) indicated some inhibition of hydrogenation activity but with OPP, PE and MEP several products were formed that were not completely identified and kinetic analysis would be difficult. We therefore focused on DBF, with which we have had some experience, and we carried out a series of studies at 3.5 MPa and 360°C. H₂S was generated in situ and NH₃ was introduced as supercooled liquid by an ISCO pump to constitute 12 kPa in the reactor. Samples of reaction products were anlayzed by g.c. using a 30-m Supelcowax (high polarity) column. The HDO of the DBF network follows two pathways. There is a hydrogenation route where single-ring products predominate, mostly cyclohexane and cyclobenzene. The other path is a hydrogenolysis route where double-ring compounds predominate, mostly cyclohexylbenzene (CHB), biphenyl (BP), and dicyclohexyl (DCH).
