PROCESS TO PREPARE METHANOL AND/OR DIMETHYLETHER |
摘要 |
A process to prepare methanol and/or dimethylether from a solid carbonaceous feedstock comprising the steps of (a) feeding an oxygen-comprising gas and the carbonaceous feedstock to a burner firing into a reactor vessel, (b) performing a partial oxidation of the carbonaceous feedstock in said burner to obtain a stream of hot synthesis gas and a liquid slag whereby both the hot synthesis gas and the liquid slag flow downwardly relative to the burner, (c) cooling the hot synthesis gas by direct contact with a liquid water-containing cooling medium, (d) performing a water shift reaction on at least part of the synthesis gas, to obtain a synthesis gas effluent, (e) performing an oxygenate synthesis using the synthesis gas effluent of step (d), to obtain a methanol and/or dimethylether containing oxygenate effluent and a first liquid water-rich by-product, wherein at least part of the first liquid water-rich by-product is used in step (c), forming at least part of the liquid water-containing cooling medium. |
