Process and system for syngas production from biomass materials

摘要

A process and system suitable for producing syngas from biomass materials. The process and system entail the compaction of a loose biomass material to remove air therefrom and form a compacted biomass material. The compacted biomass material is then introduced into a reactor and heated in the substantial absence of air so as not to combust the compacted biomass material. Instead, the compacted biomass material is heated to a temperature at which organic molecules within the compacted biomass material break down to form ash and gases comprising carbon monoxide and hydrogen gas. Thereafter, the carbon monoxide and hydrogen gas are released from the reactor, and the ash is removed from the reactor.

1. A process of producing syngas from biomass materials, the process comprising:
compacting a loose biomass material to remove air therefrom and form a compacted biomass material; introducing the compacted biomass material into a vessel of a reactor; heating the compacted biomass material within the vessel of the reactor in the substantial absence of air so as not to combust the compacted biomass material, the compacted biomass material being heated to a temperature at which organic molecules within the compacted biomass material break down to form ash and gases comprising carbon monoxide and hydrogen gas; diffusing the gases through a porous wall during the heating step, wherein relatively higher molecular weight hydrocarbons within the compacted biomass material have an increased residence time during the heating step to promote decomposition thereof into the gases; releasing the carbon monoxide and hydrogen gas from the reactor; and removing the ash from the reactor.
