摘要： PURPOSE: To enhance heat exchange amount per unit adsorbent, by heating a zeolite type adsorbent while bringing the heated adsorbent into direct contact with a heating medium such as water or steam to perform heat exchange.
CONSTITUTION: At least a part of the adsorbed water of a zeolite type adsorbent is released to regenerate said adsorbent. Steam is adsorbed with this zeolite type adsorbent bed and the temp. of said adsorbent bed is raised by the generated heat of adsorption. Subsequently, a heating medium comprising water, steam or a gaseous mixture containing steam is supplied and brought into direct contact with the adsorbent to perform heat exchange. Because adsorption heat is again generated at this time, the quantity of heat to be recovered is increased. In the next step, heated steam is withdrawn from the adsorbent bed.

摘要： PURPOSE: To provide a superior adsorbent for selective adsorption of p-xylene from C
8 arom. hydrocarbon-contg. raw materials which adsorbent is made of faufasite type zeolite having a K-based cation structure contg. Zr and proton or NH
3 .
CONSTITUTION: Faujasite type zeolite usually called zeolite X and Y is treated with an aq. soln. of a Zr cpd. such as zirconyl nitrate to carry out Zr exchange. The exchanged zeolite is then treated with an aq. soln. of a protonic acid such as hydrochloric acid or an NH
4 cpd. such as NH
4 NO
3 to carry out proton or ammonium exchange. Thus, the amts. of K, Zr and proton or NH
3 as cation components in the above zeolite are set to 60W96%, 2W25% and 2W25% of the total cation components as K, respectively. The resulting adsorbent is used in adsorption separation under the conditions of room temp.W250°C and atmospheric press.W350 kg/cm
2 to selectively separate p-xylene.
