5) beta zeolite membrane β沸石膜 1. Thebeta zeolite membranes were prepared on seeded α-Al2O3 substrate tubes with a mean pore size of 3-5 μm by the method of secondary hydrothermal growth using TEAOH as templates. 以TEAOH(四乙基氢氧化铵)为模板剂,采用预涂晶种的二次水热合成法在平均...
zeoliteisomerizationoligomerizationThe adsorption of butene-1 on Beta zeolite (H form) is studied via flow-adsorption calorimetry. Upon feeding a mixture of 2 vol % of butene-1 in nitrogen over the pre-calcined zeolite (500掳C) at room temperature, an exothermic effect is observed that is ...
