Abstract
This invention presents a novel treating process for the removal of trace quantities of olefinic impurities from a hydrocarbon process stream. Specifically, this process operates at liquid phase conditions treating hydrocarbon streams comprising substantially aromatics and naphthenes having Bromine Index values of about 50 to 2,000. A solid medium comprising a crystalline aluminosilicate zeolite and a refractory oxide is used to reduce the level of olefin impurities to Bromine Index values of 0.1 to 50.
