Abstract
The conversion of ethanol to hydrocarbons in the presence of lanthanum-modified ZSM-5 zeolite in the temperature range 3000 – 4500C at flow-type atmospheric pressure was studied and it was shown that the modification of ZSM-5 zeolite and imposed temperature affect the distribution of ethanol conversion products. Modification of HZSM-5 zeolite with lanthanum plays an important role in increasing the yield of isoparaffin hydrocarbons, as well as has a substantial impact on the quality and octane number of the catalyst. The catalyst obtained from the conversion of ethanol at 3000 – 3500C complies with the Euro-5 standard for the content of benzene (<1.0%), aromatic (<30%) and olefin (<2.0%) hydrocarbons
