【摘要】 在CO₂/二正丁胺/三乙胺浓缩稳定性同位素¹³C体系中,研究了2×2θ环（100目磷青铜丝网）、1.5×1.5×0.12三角形螺旋圈（φ0.12不锈钢丝绕制）和1.6×0.6×1.5×0.12矩形螺旋圈（亦称Helipak,φ0.12不锈钢丝绕制）等三种填料的主要性能,表明丝绕高效填料很适用于需要多理论板数的同位素化学交换过程。更多还原

【Abstract】 The major performances of three high efficiency packings were studied in the enrichment of 13C using CO2/di-n-butylamine (DNBA)/triethylamine (TEA) system. These packings consisted of 2 × 2mm Dixon rings (phosphor bronze gauze, 100 mesh), 1.5×1.5×0.12 mm triangular-section spirals (stainless steel wire φ0.12 mm) and 1.6×1.6×1.5×0.2 mm rectangular-section spirals (i.e. Helipak packings, stainless steel wire φ0.12mm). The results showed that the spiral packings are very suitable for the chemical exchange processes of isotope separation which require theoretically a large number of plates.更多还原
