31 Aug 1972TL;DR: A thermally stable, oxidation-resistant nickel-base alloy having good engineering properties for use in mechanical equipment operated at temperatures of up to 1600° F. or higher is provided by maintaining the nickel content above 50% by weight and including as essential elements from about 12 to about 18% chromium, from about 8 to 18% molybdenum and from about 0.005 to about 2.2% lanthanum by weight as mentioned in this paper.
Abstract: A thermally stable, oxidation-resistant nickel-base alloy having good engineering properties for use in mechanical equipment operated at temperatures of up to 1600° F. or higher is provided by maintaining the nickel content above 50% by weight and including as essential elements from about 12 to about 18% chromium, from about 8 to about 18% molybdenum and from about 0.005 to about 0.2% lanthanum by weight. Additional elements may be included in limited amounts provided that the average N v number of the alloy as defined herein is not substantially above about 2.5 and preferably is below about 2.4.

TL;DR: In this paper, the ability of supercritical CO to extract model contaminant compounds from GAC and subsequently drop out most of the contaminant in a liquid phase has been investigated in a pilot scale apparatus.
Abstract: A technology which has great potential for environmental control and waste remediation is contaminant removal and separation with supercritical fluids (SCF's) or supercritical fluid extraction (SFE). Pressure tuning of solvent power allows SCF processes to adapt to a wide variety of small batch oriented separations typified by environmental cleanup operations. The ability of supercritical CO[sub 2] to extract model contaminant compounds from GAC and subsequently drop out most of the contaminant in a liquid phase has been investigated in a pilot scale apparatus. Typical desorption profiles indicate an 85% removal of the compound from the carbon which allows for reuse. The desorption results have been interpreted with a generalized desorption-mass transfer model. The results of the pilot plant studies have been applied to the design of a fixed-site GAC regeneration unit consisting of a three-element desorber with two-stage flash separation. Optimization of the process centers around minimizing the cost of recycling the SCF through an efficient recompression scheme and cycle configuration in the desorber unit. An economic evaluation shows a processing cost of 10.6 cents/lb (23 cents/kg) GAC which compares favorably with thermal regeneration and incineration. This non-destructive process allows re-use of the GAC while maintaining a high adsorbate capacity,more » which reduces carbon replacement costs and significantly decreases the need for carbon disposal by landfill or incineration. 25 refs., 13 figs., 3 tabs.« less

TL;DR: In this paper, a modified carbon product is described which comprises carbon having attached at least one organic group and the organic group is present at a level of from about 0.10 to about 4.0 micromoles/m 2 of the carbon used based on nitrogen surface area of carbon.
Abstract: A modified carbon product is described which comprises carbon having attached at least one organic group. The organic group comprises a) at least one aromatic group or a C 1 -C 12 alkyl group and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group. The aromatic group or the C 1 -C 12 alkyl group of the organic group is directly attached to the carbon and the organic group is present at a level of from about 0.10 to about 4.0 micromoles/m 2 of the carbon used based on nitrogen surface area of the carbon. Also described are aqueous and non-aqueous inks and coatings and ink jet ink compositions containing the modified carbon product. A method to increase the flow of an ink, as measured by glass plate flow, by incorporating the modified carbon product as part of the ink is also disclosed as well as a method to improve the waterfastness of a print imaged by an ink composition. Lastly, non-aqueous ink and coating formulations are described which contain an appropriate solvent and a modified carbon product comprising carbon having attached at least one organic group, wherein the organic group comprises a) at least one aromatic group or C 1 -C 12 alkyl group, and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group, wherein the organic group is present in any amount.
