METHOD AND PROCESS FOR DRY DISCHARGE IN A PRESSURIZED PRETREATMENT REACTOR

摘要

A reactor for the treatment of lignocellulosic material and related methods. The reactor includes a vessel having an upper portion and a lower portion. A pressure envelope is formed between an outer wail of the vessel and at least one lower wall of the lower portion of the vessle, and the upper portion of the vessel and the pressure envelope are operatively connected with a pressurization line, such that a pressure of the pressure envelope and a pressure of the upper portion may be equalized.
