Title Upgrading of bitumen by hydropyrolysis -- A process for low coke and high syncrude yields
Date 1985-07
Description The Department of Fuels Engineering at the University of Utah has been conducting research on the chemistry and engineering of hydropyrolysis for several years. It was previously observed (Ramakrishnan, 1978; Shabtai et al., 1979) that under certain reaction conditions hydrocarbon species undergo cracking reactions with no evidence of products possessing molecular weights greater than those of the starting material. In work involving heavy feedstocks with significant (>10%) carbon residue properties, and using a coiled tube reactor, it was further observed (Bunger, 1979; Bunger et al., 1978,1981) that conversion to gaseous and liquid products with yields greater than 99% was possible. The general conditions that result in these yields are 450-600°C, 1200-2000 psig H2, and 1-30 sec residence times. The prospect of developing a noncataly tic process for conversion of heavy oils and bitumens, which also may contain a high content of metals, was very attractive.
