WebEthene aromatization reaction was studied at 400°C over HZSM-5 zeolite at different space velocities and time-on-stream (TOS). Consequently, the experimental data were obtained corresponding to the reaction proceeding over fresh (TOS = 5 min) or deactivating (TOS up to 4 hours) catalyst. WebPart 1. The conversion of ethene to ethanol. After this reaction, the reaction mixture is passed from the reactor into a condenser. How can you make ethanol industrially? Part 2. Ethanol and water have a higher boiling point than ethene, so both condense whilst any unreacted ethene gas is recycled back into the reactor. philipp straehl
