In this treatment process comprising heating a drain to a 80-370°C under pressure sufficient to retain the drain in the liquid phase, and subjecting the drain to oxidation treatment and/or decomposition treatment while supplying an oxygen-containing gas, the drain is treated in cocurrent upward gas/liquid stream and thereafter, further treated by using a solid catalyst in cocurrent downward gas/liquid stream. 排水が液相を保持する圧力下、該排水を80〜370℃に加熱して酸素含有ガスの供給のもとに酸化処理および/または分解処理する方法において、該排水を気液上向並流で処理した後、固体触媒を用いて気液下向並流で更に処理を行う。 - 特許庁
The fatty acid and the lower alcohol in a gaseous state are brought into contact by countercurrent operations in a fixed bed filled with a weakly acidic solid catalyst or brought into contact by cocurrent operations and the countercurrent operations are then performed or pseudocountercurrent operations are carried out to provide the fatty acid lower alkyl ester when the fatty acid and the lower alcohol are fed to a fixed bed-reactor filled with the weakly acidic solid catalyst and reacted. 脂肪酸と低級アルコールとを、弱酸性固体触媒を充填した固定床反応器に供給して反応させる際に、脂肪酸とガス状の低級アルコールとを弱酸性固体触媒を充填した固定床内において向流操作で接触させるか、並流操作で接触させた後、向流操作を行うか、あるいは擬似向流操作を行い脂肪酸低級アルキルエステルを得る。 - 特許庁
