1. A method for gasifying a feedstock, comprising:
- combining one or more feedstocks and one or more solid components in a treatment zone to provide a treated feedstock;
producing a raw syngas-particulate mixture by introducing at least a portion of the treated feedstock to a reaction zone of a gasifier;
producing one or more separated particulates by separating at least a portion of the raw syngas-particulate mixture in a separation zone of the gasifier;
recycling at least a portion of the one or more separated particulates into the reaction zone of the gasifier;
determining whether a property of the recycled one or more separated particulates differs from a design parameter of the gasifier;
if a difference in the property is determined, changing at least one of;
(i) an average density of solids within a solids bed of the gasifier and (i) an average cross-sectional size of the solids within the solids bed of the gasifier by adjusting at least one of an average density and an average cross-sectional size of the one or more solid components being combined with the one or more feedstocks.

Abstract
Systems and methods for gasifying a feedstock are provided. The method can include combining one or more feedstocks and one or more solid components in a treatment zone to provide a treated feedstock. At least a portion of the treated feedstock can be introduced to a reaction zone of a gasifier. The one or more solid components can have an average density and an average cross-sectional size that adjusts at least one of an average density of solids within a solids bed of the gasifier and an average cross-sectional size of the solids within the solids bed of the gasifier.
