Bimetallic promotion of cooperative hydrogen transfer and heteroatom removal in coal liquefaction; Quarterly technical progress report, December 1, 1989--February 28, 1990
The ultimate objective of this research is to uncover new catalytic processes for the liquefaction of coal and for upgrading coal-derived fuels by removing undesirable organo-sulfur, organonitrogen and organooxygen constituents. Basic to both the liquefaction of coal and the purification of coal liquids is the transfer of hydrogen from such sources as dihydrogen, metal hydrides or partially reduced aromatic hydrocarbons to the extensive aromatic rings in coal itself or to aromatic sulfides, amines or ethers. This study is exploring how hydrogen-transfer processes might be catalyzed by soluble, low-valent transition metal complexes and/or Lewis acids under moderate conditions of temperature and pressure. Preliminary results indicate that (1) nickel(0) reagents react with aluminum hydrides to form powerful reducing agents having aluminum-nickel bonds, and (2) dibenzothiophene can be desulfurized to a small extent by a combination of MeAlCl{sub 2} and 1,4-cyclohexadiene.
