Biomass conversion systems having integrated heat management and methods for use thereof

摘要

Biomass conversion systems may incorporate integrated heat management to operate more efficiently during biomass conversion. Biomass conversion systems may comprise a first fluid circulation loop comprising a hydrothermal digestion unit, and a first catalytic reduction reactor unit in fluid communication with an inlet and an outlet of the hydrothermal digestion unit; and a second fluid circulation loop comprising a reaction product take-off line in fluid communication with the first fluid circulation loop, a second catalytic reduction reactor unit in fluid communication with the reaction product take-off line, and a recycle line establishing fluid communication between the first fluid circulation loop and an outlet of the second catalytic reduction reactor unit, where the first catalytic reduction reactor unit contains at least one first catalyst and the second catalytic reduction reactor unit contains at least one second catalyst, each being capable of activating molecular hydrogen.
