对选择分子筛和硅胶作为吸附剂脱除异丁烷中少量丁烯作了一定的探索研究。当硅胶作为吸附剂时，在三种不同工艺流程下，研究了丁烯的净化深度和异丁烷回收率，异丁烷（９７％，ｖ／ｖ）中丁烯从１．８％脱除到０．０６～０．７％之间，丙烷和丙烯不能被有效脱除。当分子筛作为吸附剂时，净化深度高，能将异丁烷中的Ｃ３Ｈ８（０．５％）、Ｃ３Ｈ６（０．５％）和Ｃ４Ｈ８（１．８％）组分脱除到０．１％左右。净化的关键在于吸附剂的再生。 Some molecular sieves and silica gel as sorbent to remove a small amount of butane in isobutane made a certain exploration and research. When silica gel was used as adsorbent, the depth of cleanup of butylene and the recovery of isobutane were studied under three different process flows. Butene was removed from 1.8% in isobutane (97%, v / v) To 0.06 ~ 0.7%, propane and propylene can not be effectively removed. When the molecular sieve is used as adsorbent, the purification depth is high, and components of C3H8 (0.5%), C3H6 (0.5%) and C4H8 (1.8%) in isobutane can be removed to 0.1% about. The key to purification is the regeneration of adsorbents.
