To maintain biodiesel production as economically viable, processes for valorising the 10 wt% glycerol waste stream need to be developed. The content of this chapter discusses recent work which examines potential catalytic processes for producing value added chemicals using glycerol as a platform chemical. Significant research has focussed on catalytic reactions tailored to selectively convert oxygenates from biological resources to produce valuable chemicals. While homogenous and biological catalytic processes are important, heterogeneously catalysed reactions are considered to be more desirable and potentially more economically viable due to advantages in feedstock processing. The current transesterification process associated with biodiesel production results in a number of contaminants in the glycerol stream, such as free fatty acids and residual catalyst salts, which affects downstream processing. Special emphasis is given to understand how contaminants of various by-products interact with surfaces and identify robust catalysts while examining alternative catalytic processes for producing biodiesel with purer product streams.","PeriodicalId":43717,"journal":{"name":"Catalysis Structure & Reactivity","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77392403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, experiments with single-crystal surfaces and well-ordered films have increased our understanding of the interaction of methane with solid surfaces. Late transition metals interact weakly with methane and elevated temperatures (>400 K) are necessary to enable a significant dissociation on the hydrocarbon. In contrast, an IrO2(110) surface dissociates methane at temperatures below 200 K. Cooperative interactions between O and Ir are responsible for the binding of methane and the breaking of a C–H bond. This type of cooperative interactions involving O and a metal cation have also been seen on Ni/CeO2(111) and Co/CeO2(111) surfaces which dissociate methane at room temperature. Experiments of AP-XPS and in situ TR-XRD have shown that the active phase of metal/oxide catalysts used for the dry-reforming of methane frequently is a dynamic entity which evolves when the reaction conditions change. The addition of water to a mixture of CH4/O2 shifts the selectivity towards methanol production on CeO2/CuOx/Cu(111) and Ni/CeO2(111) surfaces. Metal-support interactions and water site-blocking play a crucial role in the conversion of methane to methanol on these catalysts.","PeriodicalId":43717,"journal":{"name":"Catalysis Structure & Reactivity","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78711812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Innovation in methane conversion chemistry and technology is essential to provide value-added chemicals and fuels, which could be an alternative to petroleum. Direct non-oxidative methane conversion (DNMC) has been studied to produce C2 (e.g., acetylene, ethylene, ethane) and aromatics (e.g., benzene and naphthalene), when combined are referred to as C2+ hydrocarbons. However, thermodynamic constraint in DNMC leads to low methane conversion, low C2+ yield, and rapid catalyst deactivation by coke. Membrane reactors comprised of active DNMC catalysts and hydrogen-permeable membranes have the potential to alleviate the thermodynamic barriers and increase methane conversion. This chapter summarizes the past research and ongoing development on DNMC reaction in membrane reactors. The catalysts, membrane materials, reactor configurations and performance for DNMC in membrane reactors are discussed. The challenges, strategies to mitigate reactor deterioration during DNMC, as well as future research and development directions to advance this technology for one-step conversion of methane to C2+ hydrocarbon fuels and chemicals are presented.","PeriodicalId":43717,"journal":{"name":"Catalysis Structure & Reactivity","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75100589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
