摘要:
The present invention provides a desulfurization agent for kerosene that can remove efficiently the sulfurs contained in kerosene under low pressure conditions and thus is excellent in an effect to inhibit carbon deposition. The desulfurization agent comprises 45 to 75 percent by mass of nickel oxide, 3 to 40 percent by mass of zinc oxide, 10 to 25 percent by mass of silica, 5 percent by mass or less of alumina and 0.1 percent by mass or less of sodium and having a BET specific surface area of 200 m 2 /g or greater.
摘要:
Disclosed is a desulfurization system for desulfurizing a hydrocarbon fuel containing a slight amount of methanol and a slight amount of water, wherein desulfurization effect can be maintained over a long time by arranging a Y-type zeolite desulfurizing agent containing at least copper in a former stage, while arranging an X-type zeolite desulfurizing agent containing at least silver in a latter stage.
摘要:
The present invention provides a desulfurization system for desulfurizing a hydrocarbon fuel containing a light amount of methanol and a slight amount of water. The desulfurization system comprises a Y-type zeolite-based desulfurizing agent containing at least copper arranged upstream of the system and an X-type zeolite-based desulfurizing agent containing at least silver arranged downstream of the system and thus can maintain desulfurization effect for a long period of time.
