The present invention relates to a process for preparing an organic carbonate, comprising contacting carbon dioxide with an alcohol in the presence of water and a catalyst in a reaction zone resulting in the production of the organic carbonate, wherein the organic carbonate is continuously removed from the reaction zone.

Organic carbonate production process

An alkylaromatics isomerisation catalyst, which catalyst comprises at least 50 wt % of an inorganic binder; at least 0.01 wt % of a Group VIII metal and 1-9 wt % ZSM-12 zeolite wherein the silica to alumina molar ratio (SAR) of the ZSM-12 zeolite is in the range of from 60 to 200, and a process for the isomerisation of alkylaromatics to provide a reaction mixture, said process comprising contacting a hydrocarbon stream comprising alkylaromatics with such catalyst.

Catalyst and isomerisation process

A process for preparing an alkylaromatics isomerisation catalyst comprising at least 0.01% wt of platinum on a carrier comprising of from 1 to 9 wt % of ZSM-12 and inorganic binder, which process comprises treating the carrier with an impregnation solution comprising a cationic platinum compound and having a pH of more than 9, and subsequently drying and calcining the impregnated carrier at a temperature of from 200 to 420&#xb0; C.; and a process for the isomerisation of alkylaromatics with the help of catalyst thus obtained.
