| Abstract | The removal of 1,3-butadiene from its C4 mixture was performed via the selective adsorption over the commercial zeolite adsorbent. The adsorption capacity of the adsorbent was studied via the repeated cycles of adsorption and regeneration by desorption until the final adsorption capacity fell short of each initial capacity. The adsorption was tested with the feed consisting of iso-butane, n-butane, trans-2-butene, 1-butene, iso-butene, cis-2-butene, 1,3-butadiene, and C5. The regeneration by desorption was conducted, upon each saturated adsorption. The effect of different regeneration gases during desorption, i.e. nitrogen and fuel gas, was investigated. It has been found that the commercial adsorbent exhibited the relatively stable adsorption performance of 1,3-butadiene under the desorption atmosphere of nitrogen gas. |
