- Аннотация: The influence of the active element in the alkylation catalyst as a component of a combined catalyst for the production of liquid hydrocarbons with increased triptane content from dimethyl ether was studied. A mixture of liquid hydrocarbons containing more than 8.5 wt % triptane was prepared under the optimum conditions (temperature 340°С, pressure 10 MPa, dimethyl ether weight space velocity 4 h–1) on a combined catalyst in the form of a physical mixture of catalysts (mean grain size 2–4 mm) for the synthesis of lower olefins, based on Mg-modified НZSM-5 zeolite, and for the alkylation, based on La- and Pd-modified HY zeolite.
