用于(yu)氣固(gu)(gu)(gu)相(xiang)或液固(gu)(gu)(gu)相(xiang)非(fei)催(cui)(cui)化反(fan)(fan)應(ying)(ying)時(shi)，床層(ceng)(ceng)(ceng)則填裝(zhuang)固(gu)(gu)(gu)體反(fan)(fan)應(ying)(ying)物。多通道(dao)固(gu)(gu)(gu)定(ding)(ding)床反(fan)(fan)應(ying)(ying)器(qi)可歸屬于(yu)固(gu)(gu)(gu)定(ding)(ding)床反(fan)(fan)應(ying)(ying)器(qi)，氣、液相(xiang)并流向下通過床層(ceng)(ceng)(ceng)，呈氣液固(gu)(gu)(gu)相(xiang)接觸。多通道(dao)固(gu)(gu)(gu)定(ding)(ding)床反(fan)(fan)應(ying)(ying)器(qi)進料、平行性(xing)高、重現性(xing)好，溫度(du)、壓力、甚攪拌速度(du)均(jun)可獨(du)立控制，包括(kuo)在線取樣(yang)分析等(deng)操作均(jun)可全(quan)自動完成，是真正的(de)全(quan)自動高通量系統。固(gu)(gu)(gu)定(ding)(ding)床反(fan)(fan)應(ying)(ying)器(qi)主要用于(yu)實現氣固(gu)(gu)(gu)相(xiang)催(cui)(cui)化反(fan)(fan)應(ying)(ying)，如(ru)氨(an)合(he)成塔(ta)、接觸氧化器(qi)、烴類蒸汽(qi)轉化爐等(deng)，用于(yu)氣固(gu)(gu)(gu)相(xiang)或液固(gu)(gu)(gu)相(xiang)非(fei)催(cui)(cui)化反(fan)(fan)應(ying)(ying)時(shi)，床層(ceng)(ceng)(ceng)則填裝(zhuang)固(gu)(gu)(gu)體反(fan)(fan)應(ying)(ying)物。

固定(ding)床(chuang)反(fan)(fan)應器(qi)的優點：催化(hua)劑(ji)不(bu)易磨損，可(ke)(ke)以較長時間連(lian)續使(shi)用(yong)，催化(hua)劑(ji)不(bu)限于(yu)顆(ke)粒(li)狀(zhuang)(zhuang)(zhuang)，網(wang)狀(zhuang)(zhuang)(zhuang)催化(hua)劑(ji)早(zao)已應用(yong)于(yu)工業上，目前(qian)，蜂(feng)窩狀(zhuang)(zhuang)(zhuang)、纖維(wei)狀(zhuang)(zhuang)(zhuang)催化(hua)劑(ji)也已被廣泛使(shi)用(yong)。多通道固定(ding)床(chuang)反(fan)(fan)應器(qi)采(cai)用(yong)可(ke)(ke)編程控(kong)制(zhi)器(qi)和計算機(ji)控(kong)制(zhi)的自動化(hua)微(wei)型實(shi)驗裝置，裝置自動化(hua)操(cao)作，各操(cao)作點的溫(wen)度、流量(liang)、壓力信(xin)號(hao)及探(tan)測(ce)器(qi)信(xin)號(hao)由系統自動采(cai)集。固定(ding)床(chuang)反(fan)(fan)應器(qi)的優點：流體的流動皆可(ke)(ke)看成(cheng)是理想置換流動，因(yin)此化(hua)學反(fan)(fan)應速(su)率較快，在完(wan)成(cheng)同樣生產能(neng)力時，固定(ding)床(chuang)反(fan)(fan)應器(qi)，所(suo)需要(yao)的催化(hua)劑(ji)用(yong)量(liang)和反(fan)(fan)應器(qi)體積較小。

小型(xing)固定(ding)(ding)(ding)床(chuang)反應(ying)(ying)(ying)器(qi)大都是(shi)圓柱形狀(zhuang)，溫(wen)度沿著軸向和(he)徑(jing)向具有(you)一定(ding)(ding)(ding)的分布(bu)形式。為了不(bu)致超溫(wen)而(er)破(po)壞催(cui)化(hua)劑，先要控制反應(ying)(ying)(ying)床(chuang)層(ceng)中的高溫(wen)度。固定(ding)(ding)(ding)床(chuang)反應(ying)(ying)(ying)器(qi)的優點(dian)：催(cui)化(hua)劑不(bu)易磨(mo)損，合肥(fei)固定(ding)(ding)(ding)床(chuang)，可以(yi)較長時間連續(xu)使用(yong)(yong)，固定(ding)(ding)(ding)床(chuang)反應(ying)(ying)(ying)裝(zhuang)置(zhi)器(qi)，催(cui)化(hua)劑不(bu)限于(yu)顆粒(li)狀(zhuang)，小型(xing)固定(ding)(ding)(ding)床(chuang)反應(ying)(ying)(ying)器(qi)，網狀(zhuang)催(cui)化(hua)劑早(zao)已應(ying)(ying)(ying)用(yong)(yong)于(yu)工(gong)業上，目前，蜂(feng)窩狀(zhuang)、纖(xian)維狀(zhuang)催(cui)化(hua)劑也已被(bei)廣泛(fan)使用(yong)(yong)。多(duo)通道固定(ding)(ding)(ding)床(chuang)反應(ying)(ying)(ying)器(qi)的優點(dian)是(shi)：結構簡單另(ling)有(you)油換熱或熔鹽換熱反應(ying)(ying)(ying)器(qi)、計算機(ji)聯機(ji)的數據(ju)采(cai)集和(he)溫(wen)度控制軟件、在線取(qu)樣六通閥(fa)、多(duo)種類(lei)型(xing)液體(ti)加料(liao)泵和(he)氣相色譜儀，供(gong)用(yong)(yong)戶訂(ding)貨時另(ling)外選擇配(pei)置(zhi)。此外，還可根據(ju)用(yong)(yong)戶要求進行設計、加工(gong)。
