菌株R08(Bacillus)具有强吸附还原Pd2+ 的能力. 用R08 将Pd2+ /γ- Al2O3 表面的Pd2+ 完全还原为Pd0,制成高分散度的Pd0/γ- Al2O3 催化剂. 该催化剂对CO催化转化为CO2 表现出高的活性,在150 ℃,通CO(2% )空气混合气、GHSV 30 000 m L·g- 1·h- 1的条件下,CO转化率100% ;而且已测单程寿命为80 h.
Strain R08 (Bacillus) has the ability to strongly reduce Pd2 +. With R08 Pd2 + / γ-Al2O3 surface Pd2 + completely reduced to Pd0, made of high dispersion Pd0 / γ-Al2O3 catalyst. The catalyst showed high activity for the catalytic conversion of CO to CO2. Under the conditions of 150 ℃, CO (2%) air mixture and GHSV of 30 000 m L · g-1 · h-1, the conversion of CO was 100% ; And one-way life of 80 h has been measured.
