    摘要： Reduction in energy consumption is had in a system for adsorptive removal of moisture and CO.sub.2 from atmospheric air by passing the feed air through consecutive beds of adsorbent comprising first alumina then molecular sieve zeolite, at near ambient temperature during adsorption of these impurities and subsequent regeneration of the sorbent laden beds by pressure reduction to about atmospheric level and purge at that level with product gas freed of water and CO.sub.2.

    摘要： A system and method is disclosed for demodulating RF amplitude modulated signals in a demodulator circuit of an EPC0 compliant RFID tag. One advantageous embodiment of the invention comprises first and second input ports, a +ve envelope detector circuit for each of the first and second input ports, a −ve envelope detector circuit for each of the first and second input ports, a +ve envelope differentiator circuit, a +ve low pass filter, a −ve envelope differentiator circuit, a −ve low pass filter, and a zero crossing detector. The zero crossing detector detects a transition in the RF input signal using a voltage difference between a +ve filtered differentiated envelope signal and a −ve filtered differentiated envelope signal.

    摘要： The present invention generally relates to vacuum pressure swing adsorption (VPSA) processes and apparatus to recover carbon dioxide having a purity of approximately ≧90 mole % from streams containing at least carbon dioxide and hydrogen (e.g., syngas). The feed to the CO2 VPSA unit can be at super ambient pressure. The CO2 VPSA unit produces three streams, a H2-enriched stream, a H2-depleted stream and a CO2 product stream. When the CO2 VPSA unit is installed between an SMR/shift reactor and a H2 PSA unit, hydrogen recovery is expected to be increased by extracting CO2, thereby increasing hydrogen partial pressure in the H2 PSA feed. The recovered CO2 can be further upgraded, sequestered or used in applications such as enhanced oil recovery (EOR).

    摘要翻译： 本发明一般涉及从至少包含二氧化碳和氢气（例如合成气）的物流中回收纯度约> 90摩尔％的二氧化碳的真空变压吸附（VPSA）方法和装置。 CO2 VPSA装置的进料可能处于超级环境压力下。 二氧化碳VPSA单元产生三个流，富H2的流，贫H2的流和二氧化碳产物流。 当二氧化碳VPSA单元安装在SMR /变换反应器和H2 PSA单元之间时，通过提取二氧化碳，从而提高H2 PSA进料中的氢分压，预期氢气回收率将增加。 回收的二氧化碳可以进一步升级，隔离或用于强化采油（EOR）等应用。
