    摘要: The invention relates to a method for formulation of a synthetic gas oil or an additive for gas oil in which an alkyl-aromatic compound or a mixture of alkyl-aromatic compounds is selected based on at least one parameter that is selected from the group that consists of the number of cycles of the aromatic core, the number of alkyl chains that are grafted to the aromatic cycle, the length of the alkyl chain or chains, the position of the aromatic cycle or cycles on the alkyl chain or chains of said alkyl-aromatic compound or compounds such that the cetane number of the synthetic gas oil or the additive for gas oil is greater than 30. The invention also relates to a process for the production of alkyl-aromatic compounds for use as a gas oil or additive.

    摘要: A process is described for producing phenylalkanes by alkylating at least one aromatic compound using at least one linear olefin containing 9 to 16 carbon atoms per molecule. The alkylation reaction is carried out in the presence of at least two different catalysts used in at least two distinct reaction zones. The selectivity for a monoalkylated products of the catalyst contained in the first reaction zone is lower than that for the catalyst contained in the second reaction zone located downstream of the first in the direction movement of the fluids.

    摘要: A process for the manufacture of a linear polyethylene with narrow molecular-weight distribution comprising polymerizing ethylene alone or a mixture of ethylene and an alpha-olefin in which ethylene represents at least about 70% by weight of the total monomers involved, in a gas-phase polymerization medium in the presence of a catalytic component containing at least one transition metal, magnesium, and a halogen, a co-catalyst comprising an alkylaluminum compound, and a monoether, the monoether having the general formula R'OR", wherein R' and R" are the same or different and each is a C.sub.1 to C.sub.8 linear or branched hydrocarbon radical or being a cyclic monoether with the oxygen forming a ring having 4 to 12 carbon atoms.
