- The program is designed to address a substantial, demonstrated need of the coprocessing community (both exploratory and development) for a technique to quantitatively distinguish the contributions of the individual coprocessing feedstocks to the various products. The carbon isotope technique is currently in routine use for other applications. Thirteen batch coprocessing tests were made with 850/degree/F/sup +/ Athabasca resid and Pittsburgh seam coal at three coal/petroleum ratios residence times of 5 and 45 min, with and without catalyst and at 780/degree/F and 1000 psig (cold) H/sub 2/. Athabasca bitumen (500/degree/F/sup +/), was separated by boiling point and hexane solubility into nine fractions. Thirty-three samples were analyzed from HRI coprocessing Run 227-53 with Maya resid and Texas lignite. Unfortunately, the feedstocks used in this run have very similar carbon isotope ratios, which reduces the precision of the calculated coal and petroleum carbon contents. Results are discussed. 1 fig., 16 tabs.
