| Abstract: | In this paper,liquid-phase hydrogenation process is emphatically studied. The process mainly contains denitrating neutralization which uses calcium carbonate instead of ammonia aqueous water,and reduction which uses catalytic hydrogenation instead of iron powder reduction. By this way,it is possible to cut off the T-acid segregation,reduce the wastes,lower material cost,improve the yield and quality of H-acid and obtain a considerable economic and social results. |
