摘要:Bimetallic, supported catalysts for production of 1-hexene from ethylene are manufactured by impregnating a porous, solid support material with at least one catalytic chromium compound and at least one catalytic tantalum compound. The bimetallic, supported catalysts have high catalytic turnover, high selectivity for 1-hexene production, a low tendency for metals to leach from the catalysts during manufacturing and use compared to catalysts manufactured using known techniques. Moreover, the catalysts can be reused in multiple synthesis runs. High turnover, high selectivity, and reusability improve yields and reduce the costs associated with producing 1-hexene from ethylene, while the absence of metal leaching reduces the potential environmental impacts of using toxic metal catalysts (e.g., chromium).
