    摘要： In various aspects, apparatuses and methods are provided for low pressure drop gas separations. In PSA processes, where there are large swings in pressure and corresponding swings in fluid velocity through the adsorbent, mechanical stresses during pressure cycling are of considerable concern. When that pressure is relieved in a lower pressure portion of the cycle, the high velocity of gas moving through the adsorbent bed can erode, strip away, or otherwise damage the channels within the adsorbent. Provided herein are methods which utilize flexible boundaries between adsorbent beds that are operated out of phase with one another. The flexible boundaries permit an increase in void space through the adsorbent during high pressure stages of the cycle and a decrease in void space through the adsorbent during low pressure stages of the cycle.

    摘要： A fuel cell system including a hydrocarbon fuel stream including a sulfur compound; a passive sorbent bed including a selective sulfur sorbent configured to remove the sulfur compound from the hydrocarbon fuel stream; SCSO reactor, and an active sorbent bed comprising a sulfur oxide sorbent, wherein the active sorbet bed is configured to receive an effluent stream from the SCSO reactor and remove at least a portion of the sulfur oxides via the sulfur oxide sorbent. During start-up of the fuel cell system, the hydrocarbon fuel stream may be directed along a first flow pathway through the passive sorbent bed to remove the sulfur compound from the fuel stream during a first time period and then directed along a second flow pathway during a second time period that does not pass through the passive sorbent bed, e.g., once the SCSO reactor/active sorbent bed have reached operating temperature.
