摘要： A process for reducing free oxygen in a gaseous hydrocarbon stream comprises the step of passing the gaseous hydrocarbon stream over a material comprising a metal selected from Ni, Co, Cu, Fe, Mn or Ag in a reduced state so that oxygen present in said stream reacts with the metal, wherein the metal in the reduced state is formed by, (i) withdrawing a portion of the hydrocarbon stream, (ii) forming a gas mixture containing hydrogen from the hydrocarbon portion, and (iii) passing the gas mixture containing hydrogen over the material containing the metal in reducible form.

摘要： A process for reducing free oxygen in a hydrocarbon gas stream comprises the steps of(i) forming a gas mixture containing hydrogen from a hydrocarbon,(ii) mixing the hydrogen gas mixture with a gaseous hydrocarbon stream containing free oxygen, and(iii) passing the resulting hydrocarbon gas mixture over a conversion catalyst that converts at least a portion of the free oxygen present in the gaseous hydrocarbon to steam.

摘要： A method for reducing the interaction between carbon monoxide present in a heat exchange medium and metals on the shell side of heat exchange reformer apparatus used for reforming of hydrocarbons by treatment of the shell-side of said apparatus with an effective amount of at least one passivation compound containing at least one element selected from phosphorus, tin, antimony, arsenic, lead, bismuth, copper, germanium, silver or gold is described. Where volatile compounds are formed by the passivation compound, the method further comprises compound recovery to prevent contamination and deactivation of subsequent process steps. The method reduces side reactions, provides improved reformer tube lifetime and allows tubes to be treated in-situ without the need for process shutdown.
