Process and apparatus for carrying out consecutive liquid phase reactions

摘要

The invention relates to a process and an apparatus for the realisation of a complex chemical reaction of gaseous components to give a liquid target product, taking into account likewise liquid intermediates. The field of application is the method of carrying out industrial reactions in reactors operated with a two- or multi-phase fluid, in particular for synthesis gas and methanol secondary product chemistry. Preferred fields of use relate to the reaction of reactive gases in liquid media incorporating fluidised catalyst particles. The optimal configuration of a sequence of part-reaction steps which are staggered with respect to space and time is achieved according to the invention by two gas components AG and BG flowing through a lower reaction zone I and an upper reaction zone II in such a manner that in the zone I the two gases AG and BG react to form a liquid intermediate CL which runs into zone II and reacts with component BG to give a liquid target product DL.
