In this invention we have developed a catalyst and process to convert ethanol to higher alcohols via Guerbet condensation chemistry at high selectivity (~90% selectivity to higher alcohols at ~50 percent one pass ethanol conversion). The unconverted ethanol will be easily recycled back to the reactor for further conversion so the ideal over all yield will be ~90%. The uniqueness of this invention is we can achieve this in one single catalytic bed over hydrogen atmosphere at 325 degrees C and 300psig (very mild condition) and also shown the catalyst steady life time greater than 200hrs with consistent selectivity and conversion.
