摘要: Processes for oxidative dehydrogenation of alkane to one or more olefins, exemplified by ethane to ethylene, are disclosed using novel catalysts. The catalysts comprise a mixture of metal oxides having as an important component nickel oxide (NiO), which give high conversion and selectivity in the process. For example, the catalyst can be used to make ethylene by contacting it with a gas mixture containing ethane and oxygen. The gas mixture may optionally contain ethylene, an inert diluent such as nitrogen, or both ethylene and an inert diluent.

摘要: Selective alloy corrosion is used to synthesize a robust and ultrafine mesoporous NiFeMn-based metal/metal oxide oxygen evolving catalyst with ligament and pore sizes in the range of 10 nm and a BET surface area of 43 m2/g. As an oxygen evolving catalyst, the mesoporous catalyst exhibits high stability (>264 hours) at a high current density (500 mA/cm2) with a low overpotential (360 mV) using a moderate electrolyte concentration (1 M KOH). The catalyst is made from non-precious metals and its fabrication is straight forward and directly applicable to large-scale synthesis.

摘要: Synthesize a nickel oxide-based oxidative dehydrogenation catalyst via a solvent-free process that comprises sequential steps a. mixing without added solvent a combination of a solid nickel precursor, a solid oxalate or oxalic acid and, optionally, a doping amount of a metal precursor for a period of time sufficient to convert the combination to a visually homogenous mixture; and b. calcining the visually homogeneous mixture at a temperature within a range of from greater than 250° C. to less than 800° C. for a time within a range of from 30 minutes to 360 minutes in an oxygen-containing atmosphere, preferably air, to form a calcined oxidative dehydrogenation catalyst. As a modification of the process, add an intermediate step between steps a. and b. to dry the homo geneous mixture at a temperature within a range of from 50° C. to 90° C. for a period of time within a range of from 10 minutes to 600 minutes to form a dried mixture. The resulting catalyst may be used in oxidative dehydrogenation of ethane.
