Zeolitic imidazolate frameworks for kinetic separation of propane and propene.
Propane/propene separation by cryogenic distillation is one of the most energy and cost intensive industrial processes. Adsorptive separation is a more energy-efficient alternative. Three isostructural zinc imidazolate zeolitic framework materials are found, for the first time, to be very promising in the separation of propene and propane based on their different diffusion rates. Fine-tuning of...
متن کاملThe impact of steam on the electronic structure of the selective propane oxidation catalyst MoVTeNb oxide (orthorhombic M1 phase).
The selective propane oxidation catalyst MoVTeNb oxide M1 was investigated by microwave conductivity, synchrotron X-ray photoelectron, soft X-ray absorption and resonant photoelectron spectroscopy under reaction conditions to identify the influence of steam on the electronic bulk and surface properties. Steam significantly increases both the conversion of propane and the selectivity to the targ...
متن کاملModifications of the AgMo3P2O14 Catalyst in the Oxidation of Propane
The catalytic performances in the oxidation of propane of the AgM@2014 catalyst are quite good, leading to 70% of propene selectivity at 7% of propane conversion. We have checked that, before reaction, results of XANES and EXAFS obtained at the MO K-edge (19999 eV) d r m those obtained by X-ray spectroscopy (oxidation state and MO number of oxygen neighbour of 5.66, Mo=O bond length=1.72A). Mer...
متن کاملRole of water in the partial oxidation of propane to acrylic acid over Mo1V0.3Te0.23Nb0.12Ox catalyst
Effects of water on the catalytic performances of MoVTeNbO catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. Obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. Presence of water induces some structural modif...
متن کاملInvestigation kinetic oxidation of PS by K2S2O8 and AgNO3 catalyst
In this research oxidation kinetic panceuo.s (P.S) by S2O8-2 at the presence of AgNO3 ascatalyst was studied.The method was spectrophotometer following absorption spectrum (P.S) inwave length of 518 nm. After improving the condition such as PH, P.S concentration, K2S2O8concentration, ionic strength, temperature, rate constant, activation energy, constant frequency,order reaction and thermo dyna...
