Potassium Hydroxide → Lanthanum nitrate

5 ml of 35 wt % lanthanum nitrate aqueous solution was prepared and its pH value was adjusted to 4.0 by KOH, while 95 ml of 70 wt % zinc nitrate aqueous solution was prepared and its pH value was adjusted to 2.0 by KOH or NH3.H2O. Said solutions were sprayed and impregnated on 70 g of active carbon carrier for 1 hr by equal-volume spraying and impregnating process, respectively, and the carrier with active component supported thereon was then dried at 150° C. for 8 hrs and calcined at 700° C. for 3 hrs. The catalyst thus prepared had a composition of: lanthanum oxide 2 wt %, zinc oxide 28 wt %, and active carbon 70 wt %.
