countercurrent reactorとは 意味・読み方・使い方

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.例文帳に追加

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
