Furthermore, atmospheric levels of methane remain the second largest greenhouse gas emitted globally. Methane can be used as a feedstock to produce dimethyl ether (DME), a clean fuel that is a substitute for fossil diesel. Production of DME as an alternative diesel fuel is a two-step process: methanol synthesis followed by methanol dehy- dration. Research has shown that supported Cu-ZnO with gamma alumina is a promising catalyst for DME production. The focus of this research is catalytic dehydration of methanol over catalysts based on nano-sized Ni, Co and Cu. The catalysts were prepared by depositing nano-sized metal par- ticles onto a mesoporous alumina support using sonolysis in a hexadecane solvent. The catalysts were separated from solution by centrifuge, dried and then evaluated for methanol dehydration reaction in a 300-mL Parr batch reactor. Initial reaction conditions were 260 ?C and 150 psig under nitrogen. The data demonstrated that Cu achieved the highest methanol conversion for DME production. DME was identified using FT-IR."},{"label":"dcterms.available","value":"2018-03-22T22:39:18Z"},{"label":"dcterms.contributor","value":", ."},{"label":"dcterms.creator","value":"Taveras, Elizabeth Christine"},{"label":"dcterms.dateAccepted","value":"2018-03-22T22:39:18Z"},{"label":"dcterms.dateSubmitted","value":"2018-03-22T22:39:18Z"},{"label":"dcterms.description","value":"Department of Materials Science and Engineering."},{"label":"dcterms.extent","value":"45 pg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/11401/78201"},{"label":"dcterms.issued","value":"2017-08-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2018-03-22T22:39:18Z (GMT).
