The effects of different process conditionson synthesis of plasticizer alcohols from syngas were investigated, which were judged by the timeand space yield of total alcohols, the distributions of plasticizer alcohols and CO conversion. Theresults indicated that the three active components Cu, Fe and Co in the catalyst were disperseduniformly on SiO2 carrier. The Cu-Fe-Co/SiO2 catalyst exhibited a wealthy and strong porestructure,which was conductive to synthesis of plasticizer alcohols. With the reaction temperatureincreasing,the mass fraction of plasticizer alcohols decreased gradually, and the time and spaceyield of total alcohols followed a trend of firstly increasing and then decreasing. The time and spaceyield of total alcohols and Co conversion increased slowly and slightly with the increase of reactionpressure. Little effect of reaction pressure appeared on distributions of plasticizer alcohols. WithGHSV increasing from 3000 h- to 8000 h", the time and space yield of total alcohols increased buthe CO conversion decreased, and the mass fraction of plasticizer alcohols收福日期:2011-05-17中國(guó)煤化工基金項(xiàng)目:中國(guó)科學(xué)院可再生能源與天然氣水合物重點(diǎn)實(shí)驗(yàn)室基金項(xiàng)目(y107CNMHG)資助第一作者:熊蓮,女,助理研究員,從事有機(jī)發(fā)棄物高效利用、石油化工相關(guān)工藝的研究通訊聯(lián)系人:陳新德,男.正高級(jí)工程卿,博士,從事有機(jī)廢棄物高效利用、石油化工相關(guān)工藝的研究;Emal:cxd.cxd@hotmail.com第3期合成氣制備增塑劑醇的初步研究471significantly.
