Organotemplate
WitrynaFor industry, a fast and organotemplate-free synthesis, a typically green route, means significant savings in energy and costs. Characterizations using XRD, SEM, 27Al and 29Si MAS NMR, and N 2 sorption techniques show that the ZSM-34-S crystals grow from the seeds of ZSM-34 crystals in an amorphous aluminosilicate. Catalytic tests of the … WitrynaThe present invention relates to a process for the alkylation of an organic compound comprising: (a) providing a catalyst comprising one or more zeolitic materials having a BEA framework structure, wherein the BEA framework structure comprises YO2 and optionally comprises X2O3, wherein Y is a tetravalent element, and X is a trivalent …
