    • The present invention provides a reactor and gasification process for the continuous controlled production of hydrogen (H2) and a by-product synthesis gas (mixture of CO+H2+CO2), such a process called a hydrogen priority poly-generation process (HPPP). The reactor uses a circulating molten iron process, which is capable of gasifying a variety of carbonaceous materials including low rank coals and biomass. The process employs an iron steam oxidation-reduction cycle in a multi-chamber reactor including a multi-vessel reactor system, where in one compartment or vessel hydrogen is produced by steam oxidation of molten iron; and in a second compartment or vessel the iron is regenerated by carbon reduction of molten iron oxide thereby producing a by-product synthesis gas (CO+H2+CO2), and excess heat which can be used to produce steam, and in a third step the iron is purified before being returned to the steam oxidation step in the process. An embodiment of this process uses low rank coals having high ash levels in a reactor, which is designed to continuously extract ash from the molten iron bath. A second embodiment uses low ash carbon materials such as highly beneficiated coals in a simpler process that produces pure streams of hydrogen and CO.
    • 本发明提供了用于连续控制生产氢气(H 2)和副产物合成气(CO + H 2 + CO 2的混合物)的反应器和气化方法,这种称为氢优先聚合生产方法(HPPP) 。 反应器使用循环铁水工艺,其能够气化各种含碳材料,包括低等级煤和生物质。 该方法在包括多容器反应器系统的多室反应器系统中使用铁蒸汽氧化还原循环,其中在一个隔室或容器中通过铁水的蒸汽氧化产生氢气; 并且在第二隔室或容器中,铁通过氧化铁水的碳还原再生,从而产生副产物合成气(CO + H 2 + CO 2)和可用于产生蒸汽的过量热,并且在第三步骤 铁在净化后再返回蒸汽氧化步骤。 该方法的一个实施方案使用在反应器中具有高灰分水平的低等级煤,其被设计为从铁水浴中连续提取灰分。 第二个实施例在较简单的方法中使用低灰分碳材料,例如高度精选的煤,其产生纯氢气和CO的流。

    • The present invention provides a process whereby pre-enrichment of water streams using a hydrogen source and a catalytic isotope exchange method at one or more remote sites to supply water with augmented deuterium concentration to a central heavy water. This central heavy water plant could be a Combined Electrolysis and Catalytic Exchange (“CECE”) heavy water production plant or a Girdler Sulfide heavy water plant. The deuterium content of water at the remote sites is increased and provides water stream(s) with augmented deuterium concentration to feed to the central heavy water production plant. This could be a first stage of the central CECE deuterium enrichment plant, increasing its capacity for heavy water production approximately in the ratio of its enrichment above natural deuterium concentrations. By relatively simple utilization of available deuterium enrichment capacity at the remote sites, advantages are achieved from a larger scale of heavy water production at the central production plant. The invention further provides systems and methods for adapting chlorate and chlorine dioxide systems which produce hydrogen to additionally produce deuterium-enriched water.
    • 本发明提供了一种方法,其使用氢源和催化同位素交换方法在一个或多个偏远地点预富集水流,以向中央重水提供具有增强的氘浓度的水。 该中央重水厂可以是一个联合电解和催化交换(“CECE”)重水生产厂或Girdler硫化物重水厂。 远程站点的水的氘含量增加,并提供具有增加的氘浓度的水流供给中央重水生产设备。 这可能是中部CECE氘浓缩厂的第一阶段,大大提高了其富含浓度高于天然氘浓度的重水生产能力。 通过相对简单地利用远程站点的可用氘浓缩能力,可以从中央生产厂的较大规模的重水生产获得优势。 本发明还提供用于调节产生氢气以再次产生富氘水的氯酸盐和二氧化氯体系的系统和方法。
