多(duo)通道(dao)反(fan)(fan)應(ying)(ying)器(qi)又稱填充床反(fan)(fan)應(ying)(ying)器(qi)，裝(zhuang)填有(you)固(gu)體(ti)催(cui)化(hua)劑(ji)(ji)或(huo)固(gu)體(ti)反(fan)(fan)應(ying)(ying)物(wu)用以實現多(duo)相反(fan)(fan)應(ying)(ying)過程的一種反(fan)(fan)應(ying)(ying)器(qi)。固(gu)體(ti)物(wu)通常呈顆粒狀，山東催(cui)化(hua)劑(ji)(ji)評價裝(zhuang)置，粒徑2～15mm左右，堆(dui)積(ji)成一定高度(du)（或(huo)厚度(du)）的床層。多(duo)通道(dao)固(gu)定床反(fan)(fan)應(ying)(ying)器(qi)的工(gong)藝(yi)組件如反(fan)(fan)應(ying)(ying)器(qi)、冷(leng)凝器(qi)以及高低壓分離器(qi)根據不同的工(gong)藝(yi)要(yao)求(qiu)，催(cui)化(hua)劑(ji)(ji)評價裝(zhuang)置定制，采用特別(bie)的內表面處理工(gong)藝(yi)和結構設(she)計，滿足不同催(cui)化(hua)劑(ji)(ji)和工(gong)藝(yi)的實驗要(yao)求(qiu)固(gu)定床反(fan)(fan)應(ying)(ying)器(qi)的優點(dian)：返混小，流體(ti)同催(cui)化(hua)劑(ji)(ji)可(ke)進行有(you)效接(jie)觸，當(dang)反(fan)(fan)應(ying)(ying)伴有(you)串聯副反(fan)(fan)應(ying)(ying)時可(ke)得較高選(xuan)擇性。

軸向(xiang)絕熱式固(gu)(gu)定(ding)床(chuang)(chuang)反(fan)(fan)(fan)應(ying)器(qi)(qi)：流(liu)體(ti)沿(yan)軸向(xiang)自上而下流(liu)經床(chuang)(chuang)層，床(chuang)(chuang)層同外界無熱交換。固(gu)(gu)定(ding)床(chuang)(chuang)反(fan)(fan)(fan)應(ying)器(qi)(qi)主要用(yong)于(yu)實現氣固(gu)(gu)相(xiang)催化反(fan)(fan)(fan)應(ying)，如(ru)氨合成(cheng)塔、接(jie)觸氧化器(qi)(qi)、烴(jing)類(lei)蒸汽轉(zhuan)化爐等，用(yong)于(yu)氣固(gu)(gu)相(xiang)或(huo)液固(gu)(gu)相(xiang)非(fei)催化反(fan)(fan)(fan)應(ying)時，床(chuang)(chuang)層則(ze)填裝固(gu)(gu)體(ti)反(fan)(fan)(fan)應(ying)物。固(gu)(gu)定(ding)床(chuang)(chuang)反(fan)(fan)(fan)應(ying)器(qi)(qi)是用(yong)于(yu)實現氣固(gu)(gu)、液固(gu)(gu)反(fan)(fan)(fan)應(ying)的連續(xu)化設(she)計而成(cheng)，應(ying)用(yong)于(yu)加氫、合成(cheng)氨等反(fan)(fan)(fan)應(ying)類(lei)別(bie)。裝填有固(gu)(gu)體(ti)催化劑或(huo)固(gu)(gu)體(ti)反(fan)(fan)(fan)應(ying)物用(yong)以實現多相(xiang)反(fan)(fan)(fan)應(ying)過(guo)程的一種反(fan)(fan)(fan)應(ying)器(qi)(qi)。
