The invention relates to a process for converting an alkyl tert-alkyl ether into an alkanol and an iso-alkane wherein the alkyl tert-alkyl ether is contacted with a hydrocracking catalyst in the presence of hydrogen under hydrocracking process conditions.

Process for converting an alkyl tert-alkyl ether into an alkanol and an iso-alkane

The invention relates to an integrated process for preparing an epoxide from an oxygenate, wherein the oxygenate is converted into a lower olefin and the lower olefin is subsequently epoxidised, and wherein isobutane obtained after hydrogenation and subsequent normal/iso separation of C4 hydrocarbons obtained as by-product of the oxygenate conversion, is converted into a hydroperoxide that is used for the conversion of the lower olefin into the corresponding epoxide.

Process for preparing an epoxide from an oxygenate

The invention relates to an integrated process for preparing an epoxide from an oxygenate, wherein the production of a lower olefin from the oxygenate and the subsequent epoxidation of the lower olefin is combined and wherein isobutene, a by-product of the lower olefin production, is converted into a hydroperoxide that is used for the conversion of the lower olefin into the corresponding epoxide.

The invention relates to a process for preparing organic hydroperoxides by oxidation of a hydrocarbon feed with molecular oxygen at supercritical conditions, which process is carried out in the presence of a separate liquid water phase that is present in an amount of 0.5 to 20% weight on the weight of the feed as a water film on the inner walls of the reactor vessel.

Process for preparing organic hydroperoxides

The invention relates to the process for preparing ethyne by the pyrolysis of ethane by heating the same for a period of time that is less than 0.5 sec in a pyrolysis reactor at a temperature in the range of 950 to 1500.degree. C., using steam as diluent gas in a steam/ethane molar ratio of at most 3.
