    • Described herein are improvements relating to a gasification reaction vessel (10) for converting carbonaceous feedstock to synthetic gas. The reaction vessel (10) being of the type having a lower section (18) with a grid (14) for retaining a bed of fluidizable and heat-retaining particulate material (16). The improvements generally consisting of an upper section (20) of the reaction vessel (10) having an enlarged average internal cross-sectional area compared to the average internal cross-sectional area of the lower section (18) so as to facilitate disengagement and removal of said synthetic gas from the bed of particulate material. Also described in an improved gasification process using an oxygen-enriched fluidization agent wherein the oxygen content is about 25 to 35 %, preferably 30-40 % oxygen based on volume. Also described are improved conditioning processes for the hot synthetic gas exiting the reaction vessel (10). The conditioning process provides a clean, cold synthetic gas ready for use in various applications such as a fuel for boiler, furnace, internal combustion engine, etc.
    • 这里描述的是将碳质原料转化成合成气体的气化反应容器(10)。 所述反应容器(10)具有具有用于保持可流动和保温的颗粒材料(16)床的格(14)的下部分(18)的类型。 通常由反应容器(10)的上部(20)组成的改进具有与下部(18)的平均内部横截面积相比具有更大的内部横截面面积,以便于脱离和移除 的来自颗粒材料床的合成气体。 还在使用富氧流化剂的改进的气化方法中描述,其中氧含量基于体积为约25至35%,优选30-40%的氧。 还描述了用于离开反应容器(10)的热合成气体的改进的调节方法。 调节过程提供了一种清洁,冷却的合成气体,可用于各种应用,如锅炉,炉,内燃机等的燃料。
