A kinetic model has been established for the transformation of (H 2 +CO 2 ) into dimethyl ether (DME) on a CuO–ZnO–Al 2 O 3 /γ-Al 2 O 3 bifunctional catalyst with excess γ-Al 2 O 3 acid function. The model considers the attenuation of methanol synthesis and the formation of paraffin byproducts due to CO 2 and water in the reaction...
Synthesis of dimethyl ether (DME) has been studied in a single reaction step, from H 2 +CO and H 2 +CO 2 , in a fixed bed reactor on CuO-ZnO-Al 2 O 3 /γ-Al 2 O 3 and CuO-ZnO-Al 2 O 3 /NaHZSM-5 hybrid catalysts. It has been proven that water content in the reaction medium (which is higher when CO 2 is fed) contributes to...
