Abstract
A method of reducing residual hydrocarbon accumulation during processing can comprise forming a permeable body (608) of a comminuted hydrocarbonaceous material within an enclosure (602). A primary liquid collection system (610) is located in a lower portion of the permeable body. The primary liquid collection system (610) has an upper surface for collecting and removing liquids. Comminuted hydrocarbonaceous material below the primary liquid collection system (610) forms a non-production zone (616). At least a portion of the permeable body (608) is heated to a bulk temperature above a production temperature sufficient to remove hydrocarbons therefrom within a production zone (614), where conditions in the non-production zone (616) are maintained below the production temperature.
