    摘要: A process for the preparation of agglomerates of aluminium oxide is disclosed. The process comprises contacting a hydrous aluminium oxide gel with an organic liquid which is essentially immiscible with water. The organic liquid is utilized in an amount such that the weight ratio of said liquid to water, as contained in the hydrous gel, lies within Region II of a plot of said ratio versus the pore volume of aluminium oxide obtained after being dried and calcined. Subsequent to the gel being contacted with the organic liquid, the gel is subjected to agglomeration conditions. Region II of the referenced plot is a region in which the slope of the curve plotting the ratio of organic liquid to water versus the pore volume, as discussed above, has a value equal to or greater than about 4.0.

    摘要: The invention pertains to a process for alkylating hydrocarbons in which an alkylatable organic compound is reacted with an alkylation agent to form an alkylate in the presence of a catalyst comprising a hydrogenating function and a solid acid constituent, with the catalyst being subjected intermittently to a regeneration step by being contacted with a feed containing a saturated hydrocarbon and hydrogen, said regeneration being carried out at 90% or less of the active cycle of the catalyst, with the active cycle of the catalyst being defined as the time from the start of the feeding of the alkylation agent to the moment when 20% of the alkylation agent leaves the catalyst-containing reactor section without being converted, not counting isomerization inside the molecule. The process according to the invention is especially attractive for the alkylation of isobutane with one or more butenes to form an alkylate with a high RON.
