摘要： Reacting organic compounds with near-critical or supercritical aqueous phases can dramatically transform the organic compounds over short time periods (on the order of minutes to hours). The reductive process is conducted in anaerobic or near-anaerobic conditions. The process works with a wide range of organic compounds and biomass sources, including cellulose, chitin, starches, lipids, proteins, lignin, and whole cells. Disposal of waste biomass is currently expensive, and can create environmental problems. The present invention allows the conversion of waste lipids (for example) into a hydrocarbon mixture similar to a sweet crude petroleum, along with volatile alkane and alkene gases (C2 to C5). This conversion allows the generation of a burnable fuel, as well as the generation of feed streams for reforming and distillation. The environmental and other costs associated with fossil fuel extraction are reduced. Reactions in accordance with the present invention may be conducted in continuous, batch, or semi-batch mode. To date, we have used both batch and stop-flow reactors to transform biomass in near-critical (320-390° C., 200-420 bar) and supercritical water (400-500° C., 400-550 bar).
摘要翻译：用近临界或超临界水相反应有机化合物可以在短时间内（约数分钟至数小时）显着转化有机化合物。还原过程在厌氧或近厌氧条件下进行。该方法与广泛的有机化合物和生物质来源合作，包括纤维素，甲壳质，淀粉，脂质，蛋白质，木质素和全细胞。废弃生物质的处理目前是昂贵的，可能造成环境问题。本发明允许将废脂质（例如）转化成类似于甜的原油的烃混合物以及挥发性烷烃和烯烃气体（C2至C5）。该转化允许产生可燃燃料，以及产生用于重整和蒸馏的进料流。与化石燃料提取相关的环境和其他成本降低。根据本发明的反应可以连续，分批或半间歇模式进行。到目前为止，我们已经使用了批量和停止流反应器来将生物质转化为近临界（320-390℃，200-420巴）和超临界水（400-500℃，400-550巴）。

摘要： A process for the preparation of organic and inorganic deuterium-tagged compounds is disclosed. The process comprises heating a deuterium oxide-solution of an organic or inorganic compound, the solution having a pH of from about 10 to about 1 to a temperature and pressure so that a supercritical reaction mass forms and one or more deuterium atoms of the deuterium oxide solvent exchanges with one or more protons of the organic or inorganic compound. After cooling the reaction solution formed from the supercritical reaction, the organic or inorganic deuterium-tagged compound is separated.
摘要翻译：公开了制备有机和无机氘标记化合物的方法。该方法包括加热有机或无机化合物的氧化氘溶液，该溶液的pH为约10至约1，使得超临界反应物质形成，并且氧化氘的一个或多个氘原子与一种或多种有机或无机化合物的质子进行溶剂交换。冷却由超临界反应形成的反应溶液后，分离有机或无机氘标记的化合物。

摘要： An environmentally-friendly method is disclosed for transforming preserved wood, for example creosote-treated or CCA-treated wood with supercritical water. The product of treating weathered creosote-treated wood is a mixture that is similar to fresh creosote. The novel system is akin to a closed-loop system for recovering and rejuvenating creosote. In another aspect of the invention, acidic supercritical water is used to extract copper, chromium, and arsenic from CCA-treated wood, or more generally, to extract metals from an organic matrix.
