Application of Inelastic Neutron Scattering to the Methanol-to-Gasoline Reaction Over a ZSM-5 Catalyst

Inelastic neutron scattering (INS) is used to investigate a ZSM-5 catalyst that has been exposed to methanol vapour at elevated temperature. In-line mass spectrometric analysis of the catalyst exit stream confirms methanol-to-gasoline chemistry, whilst ex situ INS measurements detect hydrocarbon species formed in/on the catalyst during methanol conversion. These preliminary studies demonstrate the capability of INS to complement infrared spectroscopic characterisation of the hydrocarbon pool present in/on ZSM-5 during the MTG reaction

Catalytic combustion of methane over mixed oxides derived from Co-Mg/Al ternary hydrotalcites

Methane catalytic combustion represents the most efficient and cleanest combustion style, while its widespread applications are restricted by the low-performance and costly catalysts. Our innovative cobalt-based catalysts, derived from anionic clays, provide efficient and affordable materials to replace the costly catalysts in combustors, for high efficiency and near-zero emission of environmental hazards (eg. NOx and VOCs). Our findings would benefit energy economy and environment protection, in particular reducing fuel consumption and mitigating climate changes and ensure energy security in medium term. Shanghai Pujing Chemical Company has contacted us to exploit such materials for flameless combustion of gaseous and liquid fuels
