| titleOfInvention | Process for the preparation of lower olefins |
| abstract | A process for the preparation of lower olefins which comprises the step (A) of separating in a high-pressure state a mixed fluid (I) containing dimethyl ether (DME) and methanol at a specified ratio into a gas component (II) and a liquid component (III), separating the gas component (II) into an off-gas and dimethyl ether, and then making this dimethyl ether join the liquid component (III) to obtain a liquid component (IV) containing DME and methanol at a specified ratio and the step (B) of subjecting the liquid component (IV) to depressurization and then introducing it into a reactor for the preparation of olefins to form a lower olefin fraction (V). According to this process, lower olefins are prepared from a mixed fluid (I) containing DME and methanol at a specified ratio, and therefore both the synthesize of oxygen-containing compounds and the formation of olefins can be carried out under milder conditions than those employed in preparing lower olefins from methanol alone to thereby reduce the costs of energy and equipment remarkably. Further, the process enables efficient production of lower olefin mixtures containing ethylene and propylene at desired ratios. |
