PROSES SINTESA GAS TAHAP TUNGGAL MENJADI DIMETIL ETER DENGAN MEMASUKKAN METANOL |
摘要 |
<p>Dimethyl ether (18) is produced from synthesis gas (10) in a single step by contact with a bifunctional catalyst system having a methanol synthesis functionality and a methanol dehydration functionality while maintaining (12) a methanol concentration greater than 1.0 mole %, preferably 4 to 8 mole %. The presence of the methanol increases the stability of the bifunctional catalyst system, particularly when the process is conducted in the liquid phase. The methanol can be provided by recycling (12a) byproduct methanol. <IMAGE></p> |
