FOR REFORMING OF METHANE AND CARBON DIOXIDE, PREPARATION OF COBALT BASED CATALYSTS AND PRODUCTION METHOD OF SYNTHESIS GAS

摘要

Purpose: the manufacturing method of synthesis gas includes being arranged to than existing nickel reforming catalyst with excellent reaction activity using identical and hydrogen the cobalt-base catalyst for methane and carbon dioxide reform and carbon monoxide, has improved the service life by low-temperature carbonization reaction. Construction: cobalt-base catalyst is reformed for methane and carbon dioxide indicates (X)-b (company)-c (Y)/Z. in chemical formula XIt is Pt, Pd, Rh, Ir or Ru and Y be Zr or La carriers Z is SiO2 or aluminium oxide. In 100 parts by weight of carrier Z, first is that 0.1~10.0, b is 5.0~30.0, c is 1. by weight0~30.0 component. The manufacturing method of synthesis gas includes that carbon monoxide and hydrogen manufacture synthesis gas under the exhaust gas of 1 molar ratio: 0.5~2.0 CO/H2 is by using catalyst. Manufacture is carried out under the temperature of 600~800 C, and 0.The pressure of 01~1 MPa and 500~100,000 space velocities ml/g cathr.
