The present disclosure provides a system and method for recycling intermediate product streams of at least gasoline from the MTP plant to the steam cracker plant for processing with the feedstock of the steam cracker plant to generate a higher percentage of ethylene and propylene. The steam cracker feedstock can be ethane.

Recycling system and process of a methanol-to-propylene and steam cracker plant

A process for producing olefins from oxygenates can include the following steps: (i) heterogeneously catalyzed conversion of at least one oxygenate to a product stream containing Colefins, Colefins, Colefins, Chydrocarbon compounds, and Chydrocarbon compounds; and (ii) separation of a propylene stream consisting of Colefins for at least 95 wt-%, wherein at least 10 wt-% of the propylene stream are recirculated into process step (i).

Process and plant for producing olefins from oxygenates

A process for producing olefins from oxygenates comprises the following steps: Furthermore, the invention also comprises a plant for carrying out this process.

A process for producing short-chain olefins by conversion of oxygenates in a multi-stage fixed-bed reactor, in which the individual stages for reaction zones are covered with beds of a granular, form-selective zeolite catalyst and the feed mixture containing oxygenates is added distributed over the reaction stages. An increase of the availability of the fixed-bed reactor for the olefin production with the same or an increased yield of short-chain olefins is achieved in that one or more reaction zones are charged with a distinctly reduced mass flow of the feed mixture containing oxygenates, wherein the reduced mass flow fraction is distributed over other reaction zones.
