摘要:
A hydrocarbon reforming process for reforming higher hydrocarbons using a prereformer and a primary reformer where the steam-to-carbon molar ratio ranges from 1.5 to 2.99 and the hydrogen stoichiometric ratio ranges from 0.01 to 1 or where the steam-to-carbon molar ratio ranges from 1.5 to 5 and the hydrogen stoichiometric ratio ranges from 0.01 to 0.095.
摘要:
A method and apparatus for dispensing compressed gas to a receiving vessel is provided where the pressure ramp rate is varied as a function of apparent gas density in the receiving vessel. In a first portion of the dispensing process, the time-averaged pressure ramp rate is greater than during a later portion of the dispensing process.

摘要:
An apparatus and corresponding method for dispensing compressed gas to a receiving tank is provided which includes a compressed gas source, a valve for controlling the flow of the compressed gas between the compressed gas source and the receiving tank, an electronic controller, a conduit between the valve and the receiving tank, and a density sensor for sensing the density of the compressed gas inside the receiving tank. The density sensor may be a capacitive sensor, a vibrating element sensor, or a nucleonic sensor. The electronic controller stores a predetermined set point density and the density sensor measures the density of the compressed gas in the receiving tank. The electronic controller periodically compares the density of the compressed gas with the predetermined set point density and controls the flow of compressed gas through the valve.
