    • A cyclic char gasifier process and apparatus are described wherein reactant gases are first compressed into the pores of a char fuel to react and then the reacted gases are expanded out of the char fuel pores. This cycle of compression and expansion is repeated with fresh reactant gases supplied for each compression and with reacted gases removed at each expansion. Air and steam are preferred reactant gases when the char fuel is to be gasified by oxidation. Reacted gases from such an oxidation gasifier plant are preferred reactant gases when the char fuel is to be partially gasified by devolatilization. Rapid reaction to a rich product gas can occur over the large surface area inside the char pores and the undesireable Neumann reversion reaction is suppressed by the strongly reducing conditions prevailing therein. The gases of devolatilization gasification can be used to enrichen the gases of oxidation gasification by using two cyclic char gasifier plants in a combination system. The char fuel can be placed into sealed pressure vessel containers or can be gasified in place within an underground coal formation. These cyclic char gasifier plants and systems can produce a net work output, one or more fuel gases, a devolatilized char, and a partially oxidized coke as principal products and the proportions of these products can be adjusted over a wide range to match market needs.
    • 描述了一种循环焦化气化器工艺和装置,其中首先将反应气体压缩到焦炭燃料的孔中进行反应,然后反应的气体从焦炭燃料孔中膨胀出来。 用每次压缩提供的新鲜反应气体和每次膨胀时除去反应的气体来重复这种压缩和膨胀循环。 当炭燃料通过氧化气化时,空气和蒸汽是优选的反应气体。 来自这种氧化气化炉设备的反应气体是当焦炭燃料通过脱挥发分部分气化时的优选的反应气体。 对丰富的产物气体的快速反应可以发生在焦炭孔内的大表面积上,并且不期望的诺依曼逆转反应被其中主要的强烈还原条件抑制。 挥发气化气体可用于通过在组合系统中使用两个循环气化炉装置来浓缩氧化气化气体。 炭燃料可以放置在密封的压力容器容器中,或者可以在地下煤层内气化到位。 这些循环焦化气化炉工厂和系统可以产生净工作产出,一种或多种燃料气体,脱挥发分焦炭和部分氧化焦炭作为主要产品,并且可以在广泛的范围内调整这些产品的比例以匹配市场需求。

    • In the engines of this invention the fuel is spread out over the interior pore area of a porous burner volume and the large area of contact with air needed for rapid burning is obtained in this way. The fuel may burn in three ways: partial burning of evaporated fuel in the pore spaces; partial burning of solid carbon fuel deposits in the pore spaces; complete burning of the partial oxidation products outside the pore spaces during expansion. Several engine cycles can be used to burn up any solid carbon deposits formed from the fuel so these engines can efficiently utilize high viscosity residual fuels and slurries of solid char fuels in oil even at very small piston diameters.
    • 在本发明的发动机中,燃料分散在多孔燃烧器体积的内部孔隙区域上,并且以这种方式获得快速燃烧所需的与空气接触的大面积。 燃料可能以三种方式燃烧:在孔隙空间中部分燃烧蒸发的燃料; 在孔隙空间中部分燃烧固体碳燃料沉积物; 膨胀过程中部分氧化产物在孔隙空间外完全燃烧。 可以使用几个发动机循环来燃烧由燃料形成的任何固体碳沉积物,因此即使在非常小的活塞直径下,这些发动机也可以有效地利用高粘度的残余燃料和油中固体焦炭燃料的浆料。
