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, where the reactor system has an injectively-mixed backmixing reaction chamber in fluid communication with a tubular-flow reactor. The injectively-mixed backmixing reaction chamber has a bulkhead that slides during real-time operation to either diminish or expand the internal volume of the backmixing reaction chamber. In one embodiment, the effective passageway space through the bulkhead is also variably adjustable. In another embodiment, the tubular-flow reactor shares the bulkhead so that axial bulkhead movement commensurately expands one reaction space while diminishing the other reaction space. Input gas streams enter the backmixing reaction chamber with sufficient velocity to turbulently agitate the contents of the injectively-mixed backmixing reaction chamber by injective intermixing of the alkane-containing gas feed stream and the oxygen-containing gas feed stream. A focal application is for direct (partial) oxidative conversion of natural gas to alkyl oxygenates.
1. 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 an internal volume defined by an internal surface of a housing and a surface of a component in moveably sealed interface to said internal surface;
a bulkhead for modifying said internal volume; wherein said bulkhead for modifying said internal volume moves said component to thereby modify said internal volume from a first internal volume to a second internal volume; and
an isobaric condenser downstream of the injectively-mixed backmixing reaction chamber.
2. The system of claim 1 wherein
said housing has a housing portion in opposite disposition to said bulkhead; and
said bulkhead is slideably movable to progress within said housing toward said housing portion to thereby commensurately diminish said internal volume, and said bulkhead is alternatively slideably movable within said housing to retract away from said housing portion to thereby commensurately expand said internal volume.
