1. A feed zone delivery system (2050A) for transferring carbonaceous material to an interior (101) of a first reactor (100) having a longitudinal reactor axis (AX) and at least one reactor carbonaceous material input (104A), the system comprising:

  • (a) a weigh feeder (2C1) configured to weigh and regulate a mass flow rate of weighed carbonaceous material (2C-02);

    (b) a densification system (2D0) configured to compress the weighed carbonaceous material (2C-02) received from the weigh feeder and form a densified carbonaceous material (2D-02);

    (c) a density reduction system (2F1) configured to reduce the density of the densified carbonaceous material (2D-02) after it exits the densification system (2D0) to thereby form de-densified carbonaceous material;

    (d) a gas and carbonaceous material mixing system (2G1) configured to receive said de-densified carbonaceous material and introduce a gas into said de-densified carbonaceous material to form a carbonaceous material and gas mixture, wherein the gas and carbonaceous material mixing system (2G1) comprises;

    (d1) a mixing chamber (G00);

    (d2) a first isolation valve (VG1) and a second isolation (VG2) spaced apart from one another along a length of the mixing chamber and thereby partitioning the mixing chamber into an entry section (G21), a middle section (G20) and an exit section (G19), the first isolation valve positioned between the entry section (G21) and the middle section (G20), the second isolation valve position between the middle section and that exit section (G19);

    (d3) a mixing chamber carbonaceous material stream input (G03, G03A, G03B, G03C) to the entry section, configured to receive said de-densified carbonaceous material;

    (d4) a mixing chamber gas input (G08, G08A, G08B, G08C) connected to a source of mixing gas (2G-03, 2G-03A, 2G-03B, 2G-03C) via an gas input valve (VG3, VG3A, VG3B, VG3C); and

    (d5) a mixing chamber output (G05, G05A, G05B, G05C) connected to said exit section; and

    (e) a transport assembly (2H1) connected to said exit section and configured to receive said carbonaceous material and gas mixture, and convey said carbonaceous material and gas mixture in a predetermined direction; and

    (f) a computer (COMP) configured to control at least the gas and carbonaceous material mixing system.
