摘要： A system and method for efficiently and sustainably producing propylene and acrylonitrile is disclosed which utilizes biodegradable materials, combustible materials that produce carbon dioxide and/or carbon monoxide. According to one embodiment of the invention, a source of carbon dioxide and/or carbon monoxide is utilized and the carbon dioxide and/or carbon monoxide is electrochemically reduced to ethylene. Dimerization is applied to separate the ethylene to produce 1-butene; which is isomerized to produce 2-butene. The 2-butene is metathesized to produce propylene. The propylene may then be subject to ammoxidation as desired in order to produce acrylonitrile.

摘要： Fluidizable catalysts for the gas phase oxygen-free oxidative cracking of alkanes, such as hexane, to one or more olefins, such as ethylene, propylene, and/or butylene. The catalysts comprise 1-15% by weight per total catalyst weight of one or more vanadium oxides (VOx), such as V2O5. The catalysts are disposed on an alumina support that is modified with cerium to influence catalyst acidity and characteristics of lattice oxygen at the catalyst surface. Various methods of preparing and characterizing the catalyst as well as methods for the gas phase oxygen free oxidative cracking of alkanes, such as hexane, to one or more olefins, such as ethylene, propylene, and/or butylene with improved alkane conversion and olefins product selectivity are also disclosed.

摘要： A distillation probe includes a conduit having a central axis. In addition, the distillation probe includes a baffle assembly disposed in the conduit. The baffle assembly includes a plurality of axially-spaced baffles positioned one-above-the-other in a stack within the conduit. Further, the distillation probe includes a first helical cooling coil wrapped around the conduit. Moreover, the distillation probe includes a thermally conductive layer disposed about the conduit and encapsulating the first helical cooling coil. The thermally conductive layer is configured to transfer thermal energy between the first helical cooling coil and the conduit.
