As part of the European Union's "Horizon 2020" research program, Evonik and nine project partners from five countries have succeeded in developing a novel new reactor for catalysing OXO reactions, which is 70 % more energy efficient.
Essen/Germany — The Romeao (Reactor Optimization by Membrane Enhanced Operation) project was launched in 2015 with the aim of developing a completely new type of reactor. This is used in homogeneous catalysis, in which olefins are converted into aldehydes with synthesis gas in a hydroformylation reaction.
A new membrane reactor developed by Evonik and partners is able to carry out the classic two-step process in just one single step. Previously, the chemical reaction was carried out first and then the product was separated from the catalyst. The reduction of the process to just one step is especially notable in the use of energy. The pilot reactor is 70 % more energy and resource efficient While also reducing greenhouse gas emissions by up to 45 % than the process used until now, as evaporation of larger quantities of the reaction product is avoided.
The reaction now takes place on a monolith, a kind of cylinder whose inner surface is coated with the catalyst. Its unique feature: the membrane is applied to the outside. This causes the catalyst to remain on the monolith and the reaction product to be separated by the membrane.
