  • Catalyst comprising small 10-ring zeolite crystallites and a method for producing hydrocarbons by reaction of oxygenates over said catalyst
    Patent number: 10737251
    Abstract: A catalyst material comprising 10-ring zeolite crystallites with one-dimensional non-intersecting channels wherein, the crystallites have an average length of less than 150 nm. The catalysts are useful in a method for producing hydrocarbons by reaction of oxygenates over said catalysts.

  • Catalyst for the conversion of oxygenates to olefins and a process for preparing said catalyst
    Patent number: 9616417
    Abstract: A catalyst for the conversion of oxygenates, such as alcohols or ethers, to olefins consists essentially of a selected SUZ-4 zeolite that has a Si/Al ratio of at least 20, preferably between 20 and 500, especially between 20 and 100. The basic SUZ-4 zeolite is prepared in a manner known per se, whereafter the Si/Al ratio is increased to the desired value. The selected SUZ-4 zeolite catalyst of the invention has a longer life time and a better product selectivity than the conventional/standard SUZ-4 zeolite catalysts.
