    摘要： Provided is a carbon dioxide adsorbent with which large quantities of carbon dioxide can be adsorbed and removed even under conditions having low carbon dioxide concentrations such as when under subatmospheric pressure or when under an environment having a carbon dioxide partial pressure of less than atmospheric pressure, said carbon dioxide adsorbent exhibiting excellent adsorption activity. A carbon dioxide adsorbent including at least a ZSM-5 zeolite including barium (Ba) or strontium (Sr) is characterized in that the ZSM-5 zeolite includes M-O-M bonds (M being Ba or Sr, and O being oxygen). The M-O-M bonds interact strongly with carbon dioxide, and thus carbon dioxide can be adsorbed effectively and in large volumes even under conditions having low carbon dioxide concentrations.

    摘要： To alleviate global warming while providing a liquid fuel to replace gasoline, apparatus and methods are disclosed for generating methanol from natural gas via the syngas route. Said apparatus and methods can also serve to dispose of any CO2 that is captured from fuel burning exhausts, especially from motor vehicle exhausts. With a proper choice of reagent ratios, the energy required for the methanol generation may derive from exothermic reactions yielding enough heat to make up for the endothermic reaction energy involved in steam reforming of natural gas, thus obviating the need for any substantial electric energy input. Although steam reforming of natural gas may yield a methanol-rich fuel that will outcompete gasoline by a wide margin, it would still fail by itself to significantly alleviate global warming. However, inclusion of captured CO2 in the proper ratio in the syngas reaction may yield an inexpensive conversion of said CO2 and natural gas to methanol or its derivatives without calling for any significant electric energy consumption. The preferred ratio is 1 mole of CO2 to 2 moles of H2O to 3 moles of CH4. These reagents may be introduced into a methanol synthesis reactor preferably maintained at about 250-300 C and 50-100 atm comprising a Cu—ZnO-alumina catalyst or its equivalent.

    摘要翻译： 为了减轻全球变暖同时提供液体燃料来代替汽油，公开了通过合成气路由从天然气产生甲醇的装置和方法。 所述装置和方法还可以用于处置从燃料燃烧排气中捕获的任何二氧化碳，特别是从机动车排气中排出。 通过适当选择试剂比例，甲醇生成所需的能量可能来自放热反应，产生足够的热量来弥补天然气蒸汽重整所涉及的吸热反应能量，从而避免了对任何实质的电能输入的需要。 虽然天然气的蒸汽重整可能会产生一种富含甲醇的燃料，这种燃料将大大超越汽油，但仍然无法显着缓解全球变暖。 然而，在合成气反应中以适当的比例包含捕获的CO 2可能导致所述CO 2和天然气转化成甲醇或其衍生物的廉价转化，而不需要任何显着的电能消耗。 优选的比例是1摩尔CO 2与2摩尔H 2 O相对于3摩尔CH 4。 这些试剂可以引入到优选保持在约250-300℃的甲醇合成反应器中，并且包含Cu-ZnO-氧化铝催化剂或其等同物的50-100atm。
