摘要: A high pressure purge is incorporated into the cycle of a PSA process designed for the recovery of strongly adsorbed product gas from a gas mixture. The high pressure purge stream is obtained by compressing the low pressure cocurrent purge step that precedes the countercurrent depressurization or evacuation step. The high pressure purge step is included in the cycle following the adsorption step of the process.

摘要: The strongly adsorbed component of a gas mixture is produced in enhanced purity and yield by novel PSA cycles. The basic steps of the cycles include an adsorption vessel prepressurization step, a cocurrent nonadsorbed gas production step, a cocurrent purge step with strongly adsorbed gas product and a countercurrent depressurization step which produces the strongly adsorbed gas product that is used in the cocurrent purge step. In addition to the basic steps, a first depressurization equalization step precedes or follows the cocurrent purge step and a corresponding first pressurization equalization step follows the countercurrent depressurization step. The cycle optionally includes one or two depressurization equalization steps before the cocurrent purge step and one or two corresponding pressurization equalization steps after the first pressurization equalization step.

摘要: A process for the partial oxidation of hydrocarbons, such as methane, to produce hydrogen and carbon monoxide is provided. The process is conducted by contacting a mixture of a hydrocarbon-containing gas and an oxygen-containing gas in the presence of a metal catalyst at high gas velocities and low reaction initiation temperatures. The metal catalyst is a transition metal selected from the group of nickel, cobalt, iron, platinum, palladium, iridium, rhenium, ruthenium, rhodium, osmium and combinations thereof supported on a ceria monolith. Less than 3% by volume of carbon dioxide is present in the product gas.
