Highlights of progress achieved during the quarter ending March 1984 are summarized. Discussion is presented under the headings: sulfur and nitrogen in oil shale processing; initial operation of the solids-recycle retort system; sulfur gas analysis by triple quadrupole mass spetroscopy (TQMS); and retort modeling. This quarter, the rate of SO/sub 2/ capture by oxidized oil shale and the relation between the fraction of carbonate reacted (sulfated) and the rate of reaction was studied. Meausrements were made of the decrease in SO/sub 2/ concentration in a gas (2% O/sub 2/, 0.1% SO/sub 2/ balance N/sub 2/) as it passed through a heated bed of granular oxidized oil shale. The TQMS was used to analyze grab samples from the pyrolysis section of the solids-recycle retort system during retort runs R-2 and R-3. These grab samples were analyzed for H/sub 2/S, mercaptans, thiophenes, sulfides, disulfides and COS within one hour of sampling to prevent loss of sulfur species on the container walls. 4 figures, 3 tables.
