Abstract
The present invention relates to a process for producing aromatic hydrocarbons comprising contacting a feedstream comprising an oxygenate with a catalyst composition comprising a medium pore-size aluminosilicate zeolite further comprising gallium and one or more elements selected from Group 12 of the Periodic Table. The process of the present invention is preferably performed in absence of any feed diluents.
Claims16
A process for converting oxygenates into aromatic hydrocarbons comprising
- contacting a feedstream comprising an oxygenate compound with a catalyst comprising a medium pore-size aluminosilicate zeolite further comprising gallium (Ga) and an element selected from Group 12 of the Periodic Table;
- and
- converting the oxygenate compound to the aromatic hydrocarbon.
A process for converting oxygenates into aromatic hydrocarbons comprising
- contacting a feedstream comprising an oxygenate compound with a catalyst comprising a medium pore-size aluminosilicate zeolite further comprising gallium (Ga), zinc, and 0.005-1 wt % of a promote element based upon a total weight of the zeolite, wherein the promoter element is selected from the group consisting of lanthanum (La), chromium (Cr), molybdenum (Mo) and tungsten (W);
- and
- converting the oxygenate compound to the aromatic hydrocarbon.
