Gas-phase methanol carbonylation over HMOR catalyst was investigated for the synthesis of dimethyl ether (DME) and acetic acid (HOAc). The results revealed that the selectivity of DME reached 98% and the methanol conversion was 45% under the reaction temperature of 493K. While, the selectivity of HOAc was 30% and the methanol conversion reached 80% when reaction temperature was increased to 573K. TEM, SEM, XRD, N2 physisorbtion, XPS and TG-DTG measurements were performed to characterize the texture and structure of the catalyst. Serious coking on the catalyst surface significantly limited the utilization of unmodified HMOR catalyst in the reaction.

In our work, acetic acid was used as a bio-oil model compound. Thermodynamic calculation of hydrogen production via steam reforming of acetic acid was attempted to investigate the effects of temperature (200-1100 °C), pressure（1-19 atm ）and steam to carbon ratio (1.5-10.5) on the concentration of equilibrium product gas and H2 yield. The results show that temperature has a profound effect on the steam reforming of acetic acid. Lower pressure and higher steam to carbon ratio are in favor of higher hydrogen production.

A silica supported Cu catalyst with good performance for ethylene glycol (EG) production was prepared by the hydrolysis of tetramethoxysilane (TMOS) in one phase solution using methanol as co-solvent, followed by the precipitation of copper on SiO2 by ammonia evaporation. XRD, SEM and TEM were carried out to characterize the structural and morphology properties of the catalyst. The results showed that Cu particles were homogeneously dispersed on the support and thus lead to the high catalytic performance.

Hydrocarbon fuels produced from methanol was investigated over HZSM-5 zeolite catalysts with different Si/Al ratio. About 40% of hydrocarbon yield can be obtained under the identical reaction condition over the catalysts. HZSM-5 catalyst with lower Si/Al ratio has slightly higher oil yield and less olefin content in gas products, which can be ascribed to the stronger acidity in the catalyst favorable for the conversion of intermediates to aromatics. In addition, a small amount of dimethyl ether (DME) was detected when using HZSM-5 zeolite catalyst with Si/Al ratio of 38, indicating that the intermediates from preliminary methanol reaction not sufficiently convert.
