LC2253 contains titanium tetrabutoxide and tetrahydrofuran (THF) that is used as a catalytic system in ethylene
dimerization and for production of butene-1. In this the catalytic system, THF, the modifier, reduces heavy and
polymeric compounds. Indeed, one of the important problems that exists in butene-1 plants , shutting down of pertinent
plant as the result of formation of polymer and fouling in heat exchangers after the reactor that one of its reasons is
unsuitable reserve of catalyst that leads to evaporation of THF and consequently reduction of THF in catalyst. In this
research, the effects of THF concentration variation on performance of catalyst and content of heavy compounds were
examined and optimum percent value of THF was determined.
