Tandem Reactor System Having an Injectively-Mixed Backmixing Reaction Chamber, Tubular-Reactor, and Axially Movable Interface

A reactor system for gas phase reacting of at least two fluid feed streams into a product stream, said reactor system comprising:

• an injectively-mixed backmixing reaction chamber in fluid communication with a tubular-flow reactor, said injectively-mixed backmixing reaction chamber having a backmixing reaction chamber housing;
• and
• a bulkhead in slideably-sealed interface to said backmixing reaction chamber housing;
• wherein said injectively-mixed backmixing reaction chamber has an injectively-mixed backmixing reaction chamber internal volume defined by said backmixing reaction chamber housing and by said bulkhead;
• said backmixing reaction chamber housing has a housing portion in opposite disposition to said bulkhead;
• and
• said bulkhead is slideably movable during real-time operation of said reactor system to progress within said injectively-mixed backmixing reaction chamber housing toward said housing portion to thereby commensurately diminish said injectively-mixed backmixing reaction chamber internal volume, and said bulkhead is alternatively slideably movable during real-time operation of said reactor system within said injectively-mixed backmixing reaction chamber housing to retract away from said housing portion to thereby commensurately expand said injectively-mixed backmixing reaction chamber internal volume.
