多通道固(gu)定(ding)(ding)(ding)(ding)床(chuang)(chuang)(chuang)反應(ying)(ying)(ying)器裝置(zhi)的(de)儀表如減壓(ya)閥(fa)、背壓(ya)閥(fa)、流量計以(yi)及管(guan)閥(fa)件均選用(yong)(yong)(yong)進口元(yuan)件，保證使(shi)用(yong)(yong)(yong)的(de)穩(wen)定(ding)(ding)(ding)(ding)性、可(ke)靠性和(he)安全性。固(gu)定(ding)(ding)(ding)(ding)床(chuang)(chuang)(chuang)反應(ying)(ying)(ying)器的(de)優點(dian)(dian)：催化(hua)(hua)劑不易磨損，可(ke)以(yi)較長時間連續使(shi)用(yong)(yong)(yong)，催化(hua)(hua)劑不限于(yu)顆(ke)粒狀(zhuang)，合肥固(gu)定(ding)(ding)(ding)(ding)床(chuang)(chuang)(chuang)，網(wang)狀(zhuang)催化(hua)(hua)劑早(zao)已(yi)(yi)應(ying)(ying)(ying)用(yong)(yong)(yong)于(yu)工(gong)業上，目前，蜂窩狀(zhuang)、纖維狀(zhuang)催化(hua)(hua)劑也已(yi)(yi)被廣泛使(shi)用(yong)(yong)(yong)。固(gu)定(ding)(ding)(ding)(ding)床(chuang)(chuang)(chuang)反應(ying)(ying)(ying)裝置(zhi)的(de)特點(dian)(dian)是在工(gong)作流程中工(gong)藝個設(she)備(bei)結構(gou)上比(bi)普(pu)通的(de)移動(dong)床(chuang)(chuang)(chuang)和(he)沸騰床(chuang)(chuang)(chuang)都要簡(jian)單(dan)的(de)多，但是他也有缺點(dian)(dian)，缺點(dian)(dian)就是固(gu)定(ding)(ding)(ding)(ding)床(chuang)(chuang)(chuang)加氫裝置(zhi)有一定(ding)(ding)(ding)(ding)的(de)局限性。這(zhe)點(dian)(dian)我們要記住。

固定(ding)(ding)床(chuang)(chuang)(chuang)(chuang)反(fan)應(ying)(ying)器(qi)主要用(yong)于實現(xian)氣(qi)固相(xiang)催(cui)化(hua)反(fan)應(ying)(ying)，如氨合成塔、接觸氧(yang)化(hua)器(qi)、烴類蒸汽轉化(hua)爐等，反(fan)應(ying)(ying)固定(ding)(ding)床(chuang)(chuang)(chuang)(chuang)，用(yong)于氣(qi)固相(xiang)或(huo)(huo)液固相(xiang)非催(cui)化(hua)反(fan)應(ying)(ying)時，床(chuang)(chuang)(chuang)(chuang)層則填裝固體反(fan)應(ying)(ying)物。多通道固定(ding)(ding)床(chuang)(chuang)(chuang)(chuang)反(fan)應(ying)(ying)器(qi)是一個自動化(hua)系統(tong)，用(yong)于高(gao)溫(wen)高(gao)壓或(huo)(huo)者高(gao)溫(wen)常壓下(xia)進行的催(cui)化(hua)劑(ji)的評(ping)價。裝置配備的高(gao)壓/常壓供(gong)氣(qi)系統(tong)、高(gao)壓/常壓供(gong)液系統(tong)的管線路數可以(yi)按照不同要求(qiu)來配置。多通道反(fan)應(ying)(ying)器(qi)又(you)稱填充床(chuang)(chuang)(chuang)(chuang)反(fan)應(ying)(ying)器(qi)，裝填有固體催(cui)化(hua)劑(ji)或(huo)(huo)固體反(fan)應(ying)(ying)物用(yong)以(yi)實現(xian)多相(xiang)反(fan)應(ying)(ying)過程的一種反(fan)應(ying)(ying)器(qi)。固體物通常呈顆粒狀，粒徑2～15mm左右，工(gong)業固定(ding)(ding)床(chuang)(chuang)(chuang)(chuang)，堆(dui)積成一定(ding)(ding)高(gao)度(du)(du)（或(huo)(huo)厚度(du)(du)）的床(chuang)(chuang)(chuang)(chuang)層。

固(gu)(gu)定(ding)床(chuang)反(fan)應(ying)器(qi)的(de)另一(yi)(yi)個叫法是填充床(chuang)反(fan)應(ying)器(qi)，固(gu)(gu)定(ding)床(chuang)反(fan)應(ying)裝置(zhi)器(qi)，就是裝填有固(gu)(gu)體催化劑或固(gu)(gu)體反(fan)應(ying)物(wu)用以實現多相反(fan)應(ying)過(guo)程的(de)一(yi)(yi)種反(fan)應(ying)器(qi)。固(gu)(gu)定(ding)床(chuang)加氫裝置(zhi)跟所有的(de)固(gu)(gu)定(ding)床(chuang)渣油加氫處理(li)方式都是一(yi)(yi)樣(yang)的(de)，由反(fan)響段出來的(de)加氫生成油首(shou)先被送(song)到(dao)熱(re)交換(huan)器(qi)，用新鮮(xian)質(zhi)料冷(leng)卻，然后進(jin)入(ru)空冷(leng)器(qi)。多通道固(gu)(gu)定(ding)床(chuang)反(fan)應(ying)器(qi)的(de)優(you)點是：①返混小(xiao)，流體同催化劑可進(jin)行有效接觸(chu)，當(dang)反(fan)應(ying)伴(ban)有串(chuan)聯(lian)副反(fan)應(ying)時可得較高(gao)選擇性。②催化劑機械損耗小(xiao)。
