PCT No. PCT/EP88/00184 Sec. 371 Date Oct. 24, 1989 Sec. 102(e) Date Oct. 24, 1989 PCT Filed Mar. 10, 1988 PCT Pub. No. WO88/07410 PCT Pub. Date Oct. 6, 1988.A process for manufacturing a carbon catalyst for use in NOx reduction with ammonia catalyzed by active carbons and active cokes is described. The new carbon catalyst exhibits improved catalytic activity and hence a higher yield in NO. In the manufacturing process, a mixture of ground, oxidized hard coal and binders is moulded, carbonized at temperatures between 700 DEG and 900 DEG C., and then activated with steam at a temperature of 800 DEG to 850 DEG C. for 45 to 100 minutes, until a degree of activation of 5 to 15% is obtained.
