  • Process for decreasing bromine-reactive contaminants in hydrocarbon feeds
    Patent number: 8048295
    Abstract: A process for reducing the Bromine Index of a hydrocarbon feed containing bromine-reactive contaminants that has improved cycle length and utilizes a crystalline molecular sieve catalyst. The process is carried out by contacting the hydrocarbon feed under conversion conditions with a catalyst shaped in the form of an elongated aggregate comprising a crystalline molecular sieve having a MWW or *BEA framework type. The shortest cross-sectional dimension of the elongated aggregate is less about 1/10 inch (2.54 millimeters).
    Type: Grant
