REACTOR AND PROCESS FOR DEHYDRATION OF ETHANOL TO ETHYLENE

摘要

A reactor design and configuration and a process for the catalytic dehydration of ethanol to ethylene where the reactor train is comprised of a multi-stage single reactor vessel or multiple reactor vessels wherein each stage and/or vessel has different length, internal diameter, and volume than the other stages and/or vessels and in addition the stages and/or reactor vessels are connected in series or in parallel arrangement, preferably used with an improved means of introducing the ethanol feedstock and a heat carrying inert gas to the improved reactor train.

主权项

1. An adiabatic gas phase reactor vessel for application to catalytic dehydration of ethanol to ethylene process wherein the reactor vessel comprises:
a) several stages, each stage having a different internal volume, b) said stages are stacked in a series or parallel configuration, c) each of said stages has a different internal diameter, length, and volume; d) each of said stages contains a quantity of fixed bed catalyst whose amount is different than the quantity in other stages within the reactor vessel; e) each of said stages has an inlet for receiving a mixture of hot inert gas and fresh ethanol; and f) each of said stages has an outlet for removing a mixture of ethanol, inert gas and ethylene product.
