1. An installation for continuous production of a stream comprising acrolein, said installation comprising:
a unit for converting glycerol to acrolein, a source of gaseous reaction stream comprising at least glycerol, a source of regeneration stream comprising at least oxygen,wherein the converting unit comprises:
a reactor R comprising at least two zones containing solid acid catalyst, each of the zones being used simultaneously and alternately as reaction zone and as regeneration zone in cyclical fashion, each of the zones having fluid connection by a feeding device to the source “a” of reaction stream and to the source “b” of regeneration stream, a system adapted to each feeding device allowing sequential alternation of supply with reaction stream or with regeneration stream, at least one device for withdrawing a gas mixture c1, c2, c3, with fluidic connection to the reactor, the reactor zones being controlled thermostatically with a single system of heat-transfer fluid. |
