    摘要: Diesel fuels which have good ignition qualities, good combustion emission performance and good low temperature characteristics are characterized by a cetane number of at least 45, a total aromatics content of 10 to 15 wt. pct., a polynuclear aromatics content of less than 11 wt. pct., a sulfur content of not more than 50 ppmw, a total nitrogen content (from all sources) of not more than 100 ppmw, and excellent low temperature flow properties as manifested by a pour point not higher than -12.degree. C. and a cloud point not higher than -10.degree. C.

    摘要: This invention relates to a method of preparing a metal-containing amorphous magnesia-alumina-aluminum phosphate catalyst support involving the admixture of an organic cation having a size equal to or greater than 2 Angstroms, the organic cation preferably being a tertiary or a tetraalkylammonium or phosphonium cation. The method permits recovery of a catalyst support having a controlled pore size distribution. The invention also relates to an improved catalytic support as well as an improved petroleum residua upgrading process comprising hydrotreating residua in the presence of the improved catalyst support.
