More Information
Summary:The invention discloses a catalyst for preparing furfuryl alcohol by gas-phase hydrogenation of furfuraldehyde and a preparation method. The catalyst comprises CuO, Cr2O3, La2O3 and BaO, wherein the mol ratio of CuO/Cr2O3 is 2.4-3.0; the mol ratio of CuO/La2O3 is 100-150; and the mol ratio of CuO/BaO is 10-20. The preparation method comprises the following step: treating the components with a coprecipitation method according to the use amounts to prepare the catalyst. The catalyst has relatively high activity and selectivity, the furfuraldehyde conversion rate is 100% and the furfuryl alcohol selectivity is more than or equal to 98%; and the service life of the catalyst is long and is more than 1500 hours.
