Abstract: The present disclosure provides methods of making confined nanocatalysts within mesoporous materials (MPMs). The methods utilize solid state growth of nanocrystalline metal organic frameworks (MOFs) followed by controlled transformation to generate nanocatalysts in situ within the mesoporous material. The disclosure also provides applications of the nanocatalysts to a wide variety of fields including, but not limited to, liquid organic hydrogen carriers, synthetic liquid fuel preparation, and nitrogen fixation.

Abstract: The present invention relates to a cold box cycle which allows for independent control of the heat supplied for reboilers associated with the separation columns. More specifically, the invention relates to the tight control of the hydrogen removal separation, thus avoiding the possibility of excess reboiling in this separation. Optimal reboiling also results in a lower temperature of the hydrogen depleted liquid from this separation. As this stream is used to provide a portion of the cooling at the cold end of the primary heat exchanger, lower temperatures facilitate cooling of the incoming syngas feed, reducing carbon monoxide (CO) losses into the crude hydrogen stream from the high pressure separator. Lower CO in the crude hydrogen allows for smaller hydrogen purification equipment.
