<p>Process for the manufacture of a crude alkane and/or alkene oxidation product according to which a stream of alkane and/or alkene and a stream of oxygen are fed to a catalytic oxidation reaction section comprising a first reactor and at least one other reactor, all in series, in which
- the stream of alkane and/or alkene is fed into the first reactor for catalytic oxidation with an oxygen flow in order to produce a reaction gas which is then fed successively to the following reactors in series for further catalytic oxidation;
- the stream of oxygen is divided in several oxygen flows which are fed in parallel into each of the reactors in series;
- the reaction gas is cooled down between each two successive reactors and finally produces a crude alkane and/or alkene oxidation product leaving the last reactor;
- one part of said crude alkane and/or alkene oxidation product leaving the last reactor is cooled down and recycled as recycled gas to at least one of the reactors in series while the other part of said crude alkane and/or alkene oxidation product is sent to further use.</p> |
