多通(tong)道固(gu)定(ding)床(chuang)反(fan)(fan)(fan)應(ying)(ying)(ying)器(qi)主(zhu)要(yao)(yao)用(yong)于實(shi)現(xian)氣(qi)固(gu)相(xiang)催(cui)(cui)化(hua)(hua)反(fan)(fan)(fan)應(ying)(ying)(ying)，如氨(an)合成(cheng)塔、接觸氧(yang)(yang)化(hua)(hua)器(qi)、烴類蒸汽(qi)轉化(hua)(hua)爐等。固(gu)定(ding)床(chuang)反(fan)(fan)(fan)應(ying)(ying)(ying)器(qi)主(zhu)要(yao)(yao)用(yong)于實(shi)現(xian)氣(qi)固(gu)相(xiang)催(cui)(cui)化(hua)(hua)反(fan)(fan)(fan)應(ying)(ying)(ying)，如氨(an)合成(cheng)塔、接觸氧(yang)(yang)化(hua)(hua)器(qi)、烴類蒸汽(qi)轉化(hua)(hua)爐等，用(yong)于氣(qi)固(gu)相(xiang)或液固(gu)相(xiang)非催(cui)(cui)化(hua)(hua)反(fan)(fan)(fan)應(ying)(ying)(ying)時，反(fan)(fan)(fan)應(ying)(ying)(ying)固(gu)定(ding)床(chuang)，床(chuang)層則填裝固(gu)體(ti)反(fan)(fan)(fan)應(ying)(ying)(ying)物。多通(tong)道固(gu)定(ding)床(chuang)反(fan)(fan)(fan)應(ying)(ying)(ying)器(qi)的優(you)點是(shi)：①返混(hun)小(xiao)，流體(ti)同(tong)催(cui)(cui)化(hua)(hua)劑可(ke)進行(xing)有效接觸，當(dang)反(fan)(fan)(fan)應(ying)(ying)(ying)伴有串(chuan)聯副反(fan)(fan)(fan)應(ying)(ying)(ying)時可(ke)得較高選擇性(xing)。②催(cui)(cui)化(hua)(hua)劑機械損耗小(xiao)。

對(dui)于多變量(liang)的(de)(de)固定床(chuang)催(cui)化反應過程，也可(ke)(ke)(ke)以用經典的(de)(de)分(fen)(fen)(fen)析方(fang)法(fa)設(she)計控制系統，比(bi)如頻域分(fen)(fen)(fen)析方(fang)法(fa)、根(gen)軌跡分(fen)(fen)(fen)析方(fang)法(fa)等(deng)，可(ke)(ke)(ke)以得到良好的(de)(de)調節質量(liang)。多通(tong)(tong)道固定床(chuang)反應器采用單(dan)獨流(liu)量(liang)計進樣，確(que)保準確(que)性和平(ping)行性，實驗程序(xu)采用模(mo)塊化設(she)計，功能強大使用簡單(dan)，所有參數均保存在(zai)數據庫(ku)中，固定床(chuang)裝置(zhi)，方(fang)便隨(sui)時查閱(yue)調用。多通(tong)(tong)道固定床(chuang)反應器進料、平(ping)行性高(gao)、重現(xian)性好，溫度(du)、壓(ya)力、甚攪(jiao)拌速度(du)均可(ke)(ke)(ke)單(dan)獨控制，廣州固定床(chuang)，包括在(zai)線取樣分(fen)(fen)(fen)析等(deng)操作均可(ke)(ke)(ke)全自(zi)動(dong)完成，是真正的(de)(de)全自(zi)動(dong)高(gao)通(tong)(tong)量(liang)系統。

固(gu)(gu)(gu)(gu)定(ding)床(chuang)反(fan)(fan)應(ying)器(qi)的優點：流(liu)(liu)體(ti)的流(liu)(liu)動皆可看成是(shi)理想(xiang)置換流(liu)(liu)動，因此(ci)化學反(fan)(fan)應(ying)速率較(jiao)快，在(zai)完成同樣生(sheng)產能力時，所需要的催化劑用量和反(fan)(fan)應(ying)器(qi)體(ti)積較(jiao)小。用于(yu)(yu)氣(qi)固(gu)(gu)(gu)(gu)相(xiang)或液固(gu)(gu)(gu)(gu)相(xiang)非催化反(fan)(fan)應(ying)時，床(chuang)層(ceng)(ceng)則填裝(zhuang)固(gu)(gu)(gu)(gu)體(ti)反(fan)(fan)應(ying)物。多通道固(gu)(gu)(gu)(gu)定(ding)床(chuang)反(fan)(fan)應(ying)器(qi)可歸屬于(yu)(yu)固(gu)(gu)(gu)(gu)定(ding)床(chuang)反(fan)(fan)應(ying)器(qi)，氣(qi)、液相(xiang)并流(liu)(liu)向下通過床(chuang)層(ceng)(ceng)，呈氣(qi)液固(gu)(gu)(gu)(gu)相(xiang)接(jie)觸。對于(yu)(yu)多變量的固(gu)(gu)(gu)(gu)定(ding)床(chuang)催化反(fan)(fan)應(ying)過程，固(gu)(gu)(gu)(gu)定(ding)床(chuang)反(fan)(fan)應(ying)裝(zhuang)置器(qi)，也可以(yi)用經(jing)典的分(fen)析(xi)方法設計控(kong)制系統，比如頻域分(fen)析(xi)方法、根(gen)軌跡分(fen)析(xi)方法等，可以(yi)得(de)到良好的調節(jie)質量。
