Abstract
A continuous char separation reactor (800) comprising a container (301) configured to contain a bed of char and bed solids and a settling zone (122) disposed within a first region of the container and configured to receive an input flow (180) comprising the char and bed solids. The settling zone (122) comprises a settling means (334) configured to segregate the received char and bed solids into a char fraction (001) having a ratio of char to bed solids that is at least 5× larger than that of the input flow (180) and a depleted portion (002) of the bed solids having a lower ratio of char to bed solids than that of the input flow.

A continuous char separation reactor (100, 110, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400) comprising:
- a container (301) configured to contain a bed of char and bed solids;
- a char precursor inlet (316);
- a volatilization zone (112, 412) coupled to the char precursor inlet (316) and comprising the bed solids and a volatilization gas inlet (314), the volatilization zone configured to:
- receive a char precursor via the char precursor inlet (316);
- and
- volatilize the char precursor with a volatilization gas to form the char;
- a settling zone (122) coupled to the volatilization zone and configured to receive an input flow (180) comprising the char and bed solids, the settling zone (122) comprising:
- a settling gas inlet (334) coupled to a settling gas supply (331) and configured to fluidize the setting zone at a fluidization number (U/Umf) below 3 to segregate the received char and bed solids into:
- a char fraction (001) having a ratio of char to bed solids that is at least 10× larger than that of the input flow (180);
- and
- a depleted portion (002) of the bed solids having a lower ratio of char to bed solids than that of the input flow.
A method comprising:
- providing a reactor comprising a char precursor inlet (316) and bed solids;
- receiving a char precursor via the char precursor inlet;
- volatilizing the char precursor with a volatilization gas to form char;
- conveying an input flow (180) comprising the char and bed solids to a settling zone (122);
- settling the input flow (180) to segregate the char and bed solids into:
- a char fraction (001), having a ratio of char to bed solids that is at least 10× larger than that of the input flow (180);
- and
- a depleted portion (002) having a smaller ratio of char to bed solids than that of the input flow (180);
- and at least one of:
- extracting at least a portion of the char fraction (001) via a char stream outlet (119);
- and
- gasifying at least a portion of the char fraction (001).
A continuous char separation reactor (100, 110, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400) comprising:
- a container (301) configured to contain a bed of char and bed solids;
- a char precursor inlet (316);
- a volatilization zone (112, 412) coupled to the char precursor inlet (316) and comprising the bed solids, the volatilization zone configured to:
- receive a char precursor via the char precursor inlet (316);
- and
- volatilize the char precursor with the bed solids to form the char;
- a settling zone (122) coupled to the volatilization zone and configured to receive an input flow (180) comprising the char and bed solids, the settling zone (122) comprising an actuator configured to impart mechanical energy to the settling zone to segregate the received char and bed solids into:
- a char fraction (001) having a ratio of char to bed solids that is at least 10× larger than that of the input flow (180);
- and
- a depleted portion (002) of the bed solids having a lower ratio of char to bed solids than that of the input flow.
