Enhanced durability and reactivity for zinc ferrite desulfurization sorbent

Description: AMAX Research Development Center (AMAX R D) has been investigating methods for improving the reactivity and durability of the zinc ferrite desulfurization sorbent. Zinc ferrite sorbents are intended for use in desulfurization of hog coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. The reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point in a bench-scale fixed-bed reactor. The durability may… more

Effects of Fluctuating Environments on the Selection of High Yielding Microalgae

Description: Microalgae have the potential of producing biomass with a high content of lipids at high productivities using seawater or saline ground water resources. Microalgal lipids are similar to vegetable oils and suitable for processing to liquid fuels. Engineering cost analysis studies have concluded that, at a favorable site, microalgae cultivation for fuel production could be economically viable. The major uncertainties involve the microalgae themselves: biomass and lipid productivity and culture st… more

Analytical laboratories method No. 4017 - the radiometric nondestructive analysis of Uranium-235 in uranium tetrafluoride

Description: This method permits the nondestructive measurement of U-235 in uranium tetrafluoride (UF/sub 4/) using a Ge(Li) gamma spectrometer. The method was evaluated for UF/sub 4/ in the 0.20 to 1.25 wt% U-235 concentration range, but it could be easily extended to higher U-235 concentrations by using the appropriate standard. A nondestructive U-235 measurement can be performed in about 20 minutes. No measurement interferences have been observed.

Mechanical properties of rocks at high temperatures and pressures: Final report

Description: During the final year of the grant, we have investigated (1) why the strengths of rocks decrease with increasing temperature and in the presence of water through study of the fracture process in Westerly granite and Sioux quartzite specimens deformed in extension (some in true tension), (2) frictional strengths of rocks at high temperatures, (3) the stability of boreholes in fractured rock, and (4) slip in biotite single crystals (in that biotite is probably the weakest and most ductile of the … more

Flexible Foot Test Assembly

Description: A test model of the flexible foot support was constructed early in the design stages to check its reactions to applied loads. The prototype was made of SS 304 and contained four vertical plates as opposed to the fourteen Inconel 718 plates which comprise the actual structure. Due to the fact that the prototype was built before the design of the support was finalized, the plate dimensions are different from those of the actual proposed design (i.e. model plate thickness is approximately one-half… more
