Space ... It's Not Just for Astronauts

“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the drug store, but that's just peanuts to space.” -- Douglas Adams (British comic Writer, 1952-2001)

Although I've said this many times before, it is worth repeating repeating repeating ... The Desulfurization Blog performs two (2) useful functions.
1) The Blog presents information on desulfurization
2) It also presents tips and tricks that will be helpful no matter what area of technology you are researching.
So, today I present the NASA Technical Reports Server (NTRS) (http://ntrs.nasa.gov/search.jsp). NASA is best known for its spacerelated work. But the items in the NTRS database cover a broad range of technologies.
For example, a search for "desulfurization" yields a number of results, like the following ...

Abstract: Desulfurization of the hot reformate gas produced by catalytic partial oxidation or autothermal reforming of heavy fuels, such as JP-8 and jet fuels, is required prior to using the gas in a solid oxide fuel cell (SOFC). Development of suitable sorbent materials involves the identification of sorbents with favorable sulfidationequilibria, good kinetics, and high structural stability and regenerability at the SOFC operating temperatures (650 to 800 C). Over the last two decades, a major barrier to the development of regenerable desulfurization sorbents has been the gradual loss of sorbent performance in cyclic sulfidationand regeneration at such high temperatures. Mixed oxide compositions based on ceria were examined in this work as regenerablesorbents in simulated reformate gas mixtures and temperatures greater than 650 C. Regeneration was carried out with dilute oxygen streams. We have shown that under oxidative regeneration conditions, high regeneration space velocities (greater than 80,000 h(sup -1)) can be used to suppress sulfate formation and shorten the total time required for sorbent regeneration. A major finding of this work is that the surface of ceria and lanthanan sorbents can be sulfidedand regenerated completely, independent of the underlying bulk sorbent. This is due to reversible adsorption of H2S on the surface of these sorbents even at temperatures as high as 800 C. La-rich cerium oxide formulations are excellent for application to regenerative H2S removal from reformate gas streams at 650 to 800 C. These results create new opportunities for compact sorber/regenerator reactor designs to meet the requirements of solid oxide fuel cell systems at any scale.
