Abstract: This relates to manufacturing polybutene using C4-raffinates and LPG. The manufacturing method comprises: (A) mixing raffinate and LPG in the ratio of 1:0.25-4; (B) polymerizing continuously in the presence of Friedel-Craft catalyst; and (C) removing the activity of catalyst residue by caustic soda. Pref. C4 raffinate is composed of 10-20 wt.% butane, 20-30 wt.% 1-butene, 40-50 wt.% isobutene, 0.5-3 wt.% 1,3-butadiene, and 10-20 wt.% trans- and cis-2-butene. Also the claimed manufacturing system comprises: impeller propelled multitubular reactor (1); in-line type and stirring type mixer (2,2'); the first and second tank (3,3'); filtering tank (4) and film evaporator (5).
