Yield of Dimethyl Ether and Gasoline as a Function of Morphology of the ZSM-5 Catalyst
In this project, the catalytic behavior of some zeolite ZSM-5 crystals was evaluated. These crystals were both commercial and prepared at Luleå University of Technology. Catalytic tests done at 250°C and 370°C. Among the tested crystals there were big coffin shaped single crystals and also agglomera...
