    摘要: A method for prolonging the life of a defluorinator material contained within an alkylation process product stream defluorination zone used to remove organic fluorides from a product stream produced by an alkylation process that utilizes an alkylation catalyst containing HF and sulfone. The life of the defluorinator material is extended by reducing the amount of organic fluorides produced in the alkylation process through the addition of trifluoromethanesulfonic acid to the HF/sulfone alkylation catalyst.

    摘要: Linear alpha-olefin formation via oligomerization of ethylene using transition metal catalysis leads to a Schultz-Flory distribution of oligomers. At modest temperatures formation of heavy oligomers which are waxy solids only partly soluble in the LAO product mix causes reactor plugging and curtailing the time of continuous runs. Recycling a portion of a lighter oligomeric fraction obviates this problem and permits runs uninterrupted by solids formation.
