An electron beam radiation technology was adapted to remove SO₂ and NO_(x) simultaneously, which leaded to the production of an ammonium sulfate and an amonium nitrate in an existence of ammonia and water or ammonium hydroxide. Removal efficiencies of both SO₂ and NO_(x) were influenced by irradiated dose, inlet gaseous temperature and concentrations of water and ammonia (or ammonium hydroxide). The removal efficiency of SO₂ and NO_(x) could reach up to 95% at 10 - 20 kGy, when adding ammonia or ammoniun hydroxide with at least more than the stoichiometric ratio based on SO₂ and NO_(x) concentrations. In gas flow rates ranged from 2.5 to 20 liter/min, the removal efficiencies of SO₂ and NO_(x) showed nearly unchangeable values. The optimum reaction temperature were ranged from 90 to 100 ℃.
전자빔에 의한 2기능성 모노마로 개질된 고용융강도 Polypropylene의 제조 및 물성에 관한 연구

HMS(High Melt Strength) polypropylene was manufactured by grafting bifunctional monomers, HDDA(1,6-hexanediol diacrylate) and TPGDA(tripropylene glycol diacrylate), under an electron beam irradiation. Complex viscosities in melt state of the modified polypropylene, which had been measured by means of ARES, were sensitive to the irradiated dose and the concentration of monomer. Complex viscosity at 190℃ of homopolypropylene modified by TPGDA could increase to 132290 Pal from 5039 Pas of homopolypropylene. The complex viscosity of modified polypropylene could be correlated with average molecular weights (M ̄_(v),M ̄__(n), M ̄_(L)) as the following equation: ◁그림참조▷(원문을 참조하세요)
