Abstract: A system for optimizing storage of gas in a storage vessel includes a storage vessel, a gas supply source selectively coupled to the storage vessel to supply gas to the storage vessel, a pressure gauge to measure a pressure within the storage vessel, a plurality of adsorbent materials, a measurement device configured to determine at least one of a weight or a mass of at least the storage vessel, and a computing device. Each of the plurality of adsorbent materials is separately disposed in the storage vessel for individual evaluation. The computing device is communicatively coupled to the measurement device and configured to process information based on the measured weight or mass determined by the measurement device. The computing device is configured to determine a density, an adsorption capacity, and a deadsorption rate of each adsorbent material disposed in the storage vessel based on information determined by the measurement device.

Abstract: A fueling module is described for supplying gaseous fuel to a torch, a thermal sprayer, a fuel cell, a thermal deburrer, or a fullerene-manufacture apparatus at an elevated pressure from a relatively low pressure gaseous fuel source such as a natural gas supply system. The fueling module also can include a selectively-operable alternate system for supplying such compressed gaseous fuel for other applications, including the recharging of one or more storage vessels. The fueling module includes features by which its gaseous fuel discharge pressure can be infinitely varied and preselectively adjusted within the capabilities of the fueling module's compressor device. The fueling module also includes features for cooling and filtering oil from a compressor to improve lifespan and enable operation of the fueling module at greater input gas pressures and greater output gas pressures under more strenuous operating conditions.
