Description

ZEOCAT '95 is the eleventh in the series of symposia devoted to special fields of zeolite chemistry. Six plenary lectures, forty oral and forty-two poster presentations were included in the program. The accepted papers cover every aspect of catalysis on microporous materials. A significant number of the contributions describe the synthesis, modification, instrumental and chemical characterisation of zeolites and other micro- and mesoporous materials. Catalytic reactions involve hydrocarbon cracking, nucleophilic aromatic substitution, methanol to hydrocarbon conversion, hydration of acetylene, various alkylation reactions, redox transformations, Claisen rearrangement, etc.
