Abstract
A method for forming a cobalt-containing Fischer-Tropsch catalyst involves precipitating a cobalt oxy-hydroxycarbonate species by turbulent mixing, during which a basic solution collides with an acidic solution comprising cobalt. The method further involves depositing the cobalt oxy-hydroxycarbonate species onto an acidic support to provide a catalyst comprising cobalt and the acidic support. The acidic support comprises a zeolite, a molecular sieve, or combinations thereof.
