Description
本発明は、水素および酸化炭素(CO、CO2)を原料ガスとして、平衡転化率を超える転化率でメタノール合成を行う反応プロセスである。本発明は、触媒層中にそこでのメタノール蒸気圧の露点以下の冷却面を存在させて、この冷却面において生成メタノールを液化させ、この液相のメタノールを反応系外に抜き出すことによって濃度勾配場を生起・維持せしめ、而して、原料濃度を高い水準に維持して反応速度の低下を抑えるようにした点によって特徴づけられる。即ち、本発明においては、反応系内に生成メタノールが凝縮する温度場を設けて生成メタノールを液化・滴下させて系外に抜き出すことによって、反応サイトにメタノール濃度勾配場を生起・維持せしめている点に特徴があり、それによって反応系において、原料濃度が低下する因子を除去し続けるようにしている。
19はシール材である。
合成(原料)ガス流量:200ml/分、圧力:10atm〜40atm(1MPa〜4MPa)、温度:220℃および240℃、合成(原料)ガスの組成:Ar=2.98%、CO=31.09%、CO2=5.05%、H2=残部
冷却体(冷却管)4における冷却水入口温度=30℃であり、出口温度は冷却水流量(125ml/分程度)により60℃〜80℃の間で変動した。生成物導出口9の気相メタノールをガスクロマトグラフィー分析によってCO、CO2の転化率を算出した。220℃で行った反応における結果を、図2に示す。図2において、横軸は圧力(atm)、縦軸はCO転化率である。圧力:40atm(4MPa)で、冷却体(冷却管)4に冷却水を通した反応におけるメタノールの純度は96.9%であった。
