A continuous or semi-continuous process for the production of triptane and/or triptene from methanol and/or dimethyl ether in the presence in a reactor of an effective concentration of catalyst active for the conversion of methanol and/or dimethyl ether to triptane and/or triptene in which process co-produced water is separated from the catalyst as a vapour phase whilst the catalyst is retained in a liquid or solid phase. Preferably, the catalyst comprises zinc halide and is maintained in said reactor in an active form and an effective concentration. Apparatus for use in the process may comprise a reactor having at least one reaction zone and at least one separation zone.

La présente invention concerne un procédé continu ou semi-continu permettant la production de triptane et/ou de triptène à partir d'éther de méthanol et/ou d'éther diméthylique en présence, dans un réacteur, d'une concentration efficace de catalyseur permettant la transformation d'éther de méthanol et/ou d'éther diméthylique en triptane et/ou en triptène. Dans ce procédé, l'eau co-produite est séparée du catalyseur en phase vapeur, alors que le catalyseur est maintenu en phase solide ou en phase liquide. De préférence, le catalyseur comprend un halogénure de zinc et il est maintenu dans ledit réacteur dans une forme active et dans une concentration efficace. Un dispositif pouvant être utilisé pour la mise en oeuvre de ce procédé peut comprendre un réacteur ayant au moins une zone de réaction et au moins une zone de séparation.
