摘要:
A process for the desulfurization of a fuel cell feed stream, wherein a sulfur contaminated hydrocarbon feed stream within a fuel cell system is desulfurized by passing it over a catalyst adsorbent containing from about 30 percent to about 80 percent nickel or a nickel compound, from about 5 percent to about 45 percent silica as a carrier, from about 1 percent to about 10 percent alumina as a promoter and from about 0.01 percent to about 15 percent magnesia as a promoter. The invention also includes a fuel cell system utilizing this catalyst adsorbent.
摘要:
A method for producing a substantially desulfurized hydrocarbon fuel stream at temperatures less than 100° C. including providing a nondesulfurized fuel cell hydrocarbon fuel stream and passing the fuel stream through a sulfur adsorbent system containing a specialized sulfur adsorbent containing hydrated alumina to produce a substantially desulfurized hydrocarbon fuel stream.
摘要:
A method is disclosed for authorizing a purchase transaction made using a purchasing device associated with a financial account and communicating with a point-of-sale (POS) terminal. In one embodiment, the method may include determining a physical location of the purchasing device during the purchase transaction based on location information provided by the purchasing device. Further, the method includes determining a physical location of the POS terminal during the purchase transaction. Based on the identified locations of the purchasing device and POS terminal, a proximity of the purchasing device to the POS terminal is determined. The method may also include authorizing the purchase transaction based on the determined proximity of the purchasing device to the POS terminal.
摘要:
A method for producing a substantially desulfurized hydrocarbon fuel stream at temperatures less than 100° C. including providing a nondesulfurized fuel cell hydrocarbon fuel stream and passing the fuel stream through a sequential sulfur adsorbent bed system containing at least one selective sulfur adsorbent and a calcium exchanged zeolite to produce a substantially desulfurized hydrocarbon fuel stream.
摘要:
An arrow extension for providing GPS information of the location of an arrow is presented. The extension has a first end that has a receiving port for being coupled to an arrowhead. The extension has a power source for providing power to the extension. The power source has an actuator for changing a state of the power source. The power source also has a charging port for charging the power source. The extension has a GPS module, for determining a location and a transmitter/receiver for transmitting and receiving wireless signals. The wireless signals may be received by a device for displaying the location received in the wireless signal.
摘要:
The present invention is a process for removing sulfur-containing compounds from gaseous fuels and hydrocarbons, such as natural gas, at temperatures of less than about 100° C. The sulfur-contaminated feedstream is placed in intimate contact with a catalyst-sorbent which comprises a noble metal, a zeolite, and an alumina in a single reactor bed.
