Abstract
The present invention relates to an intensification of the synthetic process for the preparation of dialkyl ether from alcohol by using a conical fixed bed reactor integrated with distillation coupled conical polishing reactor.
Claims10
An intensified process for preparation of dialkyl ether comprising:
- dehydrating alcohol in a step conical fixed bed reactor coupled with a polishing reactive distillation unit by injecting a liquid alcohol, at a flow rate of 2.65-8.5 ml·min−1 and WHSV of 0.5-1.6 h−1 at temperature in the range of 200-260° C. under 1-10 bar pressure at reactor system to obtain dialkyl ether, wherein said process is catalyst independent.
A step conical fixed bed reactor comprising:
- i. Heat Exchanger (FIG. 1, 2);
- ii. Phase Separator-1 (FIG. 1, 3);
- iii. Reactive Distillation Column (FIG. 1, 4);
- iv. Liquid Collector (FIG. 1, 5);
- v. Phase Separator-2 (FIG. 1, 6);
- vi. Demister pad (FIG. 1, 7);
- vii. Perforated screen for catalyst support (FIG. 1, 8);
- viii. Polishing Catalyst (FIG. 1, 9);
- ix. Back Pressure Regulator (BPR) (FIG. 1, 10);
- x. Level Control Indicator (LCR) (FIG. 1, 11);
- and
- xi. Reflux Inlet (FIG. 1, 12).
