TH26862EX - Improved new cycles for linear paraffin purification - Google Patents

Abstract

Linear paraffin purification process Which will touch the hydrocarbon current Which contains linear paraffin contaminated with aerobic, sulfur-containing compounds Nitrogen-containing compounds, and oxygen-containing compounds, and colored matter, and also have a decay factor up to approximately 5% by weight by the aforementioned decay from the effluent. It goes through a new cycle with contact with solid adsorbents such as NaX zeolites or MgY zeolites; After absorbing The sorbent is decomposed with an aerobic alkyl-substrate emitter, such as toluene, whereby a support containing the sorbent is required. To be evacuated, the portion that flows out of the initial adsorption cycle will have a level of the evaporator and may undergo a new cycle to the hydrocarbon-type feed current. Before the impurity is removed from the adsorbent by dehydration, the emitter replaces the inserted linear paraffin, which is then re-cycled through the hydrocarbon-fed current.
