原始语种摘要: Еffective selective catalysts deposited on monolithic metal blocks are developed and tested in reactions of dimethyl ether and diisopropyl ether production at atmospheric pressure from methanol and isopropyl alcohol, correspondingly. The catalysts active phase is based on compounds of Ni, Cu, Mo, W, V and zeolites. The presence of rare-earth elements in the catalysts composition stabilized their activity. The increase of the carrier acidity of the catalyst results in significant increase of iso-propanol transformation, whereas the selectivity in respect to diisopropyl ether decreases slightly. The optimum catalyst composition for diisopropyl ether synthesis is based on molybdenum and nickel compounds. Highly effective stable catalysts providing production of dimethyl ether from methanol...
