Screened multiwire, PVC insulated tinned copper cable was gasified with steam at high temperature (HTSG) under atmospheric pressure for recovery of cooper. Gases from the process were additionally equilibrated at 850°C on the bed of calcined clay granules and more than 98% of C+H content in the cable was transformed to non-condensing species. Granules prepared from local clay were generally resistant for chlorination, there was also almost no deposition of metals, Cu and Sn, on the catalytic bed. It was found that 28% of chlorine reacted to form CaCl2, 71% was retained in aqueous condensate and only 0.6% was absorbed in alkaline scrubber. More than 99% of calcium existed in the process solid residue as a mixture of calcium chloride and calcium oxide/hydroxide. PVC and other hydrocarbon constituents were completely removed from the cable sample. Copper was preserved in original form and volatilization of copper species appeared insignificant. Tin was alloying with copper and its volatilization was less than 1%. Fractionation and speciation of metals, chlorine and calcium were discussed on the basis of equilibrium model calculated with HSC Chemistry software. High temperature steam gasification prevents direct use of the air and steam/water is in the process simultaneously gaseous carrier and reagent, which may be recycled together with hydrocarbon condensates.

The paper presents results of internal mobility investigations of Na+ and Nd3+ cations in molten binary system NaClNdCl3 at 1023, 1073 and 1123 K. Results of investigations have been compared with literature data for KClNdCl3 system. It has been found that internal mobility of Na+ ions increases with temperature and is higher than mobility of its K+ analogues. It has also been found that for NaClNdCl3 system internal mobility of Nd3+ does not depend on the melt composition in the range of NdCl3 equivalent fractions 0.50 < yNd <-1, whereas for KClNdCl3 system this independence begins at NdCl3 equivalent fraction of 0.80. Moreover, internal mobility of Nd3+ seems almost independent of temperature.

Abstract Gasification of oat grains with steam at normal pressure has been performed in a laboratory scale. Experiments were carried out in a vertical quartz reactor, with a steady flow of the steam and immediate tars conversion at 900ºC on the catalytic bed prepared from local clay with simple additives. Condensation of steam excess enabled essential elimination of non-volatile components of the gas stream. Condensates were analyzed with GC-MS. The highest level of organic compounds was detected in experiment with non-catalytic bed of small quartz pieces (90.2 mg/15 g of oat grains) and successful decreased by 86% for original clay without additives (precursors), 94% for clay with magnesium precursor, 97% with iron and more than 99% with calcium one.
