    摘要: 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.

    摘要: A method is disclosed for converting syngas to Fischer-Tropsch (F-T) hydrocarbon products. A synthesis gas including carbon monoxide and hydrogen gas is provided to a F-T reactor. Also, acetylene is supplied to the F-T reactor. The ratio of the volume of acetylene to the volume of synthesis gas is at least 0.01. The synthesis gas and acetylene are reacted under suitable reaction conditions and in the presence of a catalyst to produce F-T hydrocarbon products. The F-T hydrocarbon products are then recovered from the reactor. The synthesis gas and acetylene may be provided in a combined feed stream or introduced separately into the reactor. The acetylene enhanced syngas conversion in a F-T reactor results in the synthesis of F-T products which have a tighter distribution of intermediate length carbon products than do F-T products synthesized according to conventional methods.

    摘要: An integrated process for producing liquid fuels from syngas via a two-stage Fischer-Tropsch reaction is disclosed. The first stage of the Fischer-Tropsch chemistry is performed using conditions in which chain growth probabilities are relatively low to moderate, and the product of the reaction includes a relatively high proportion of low molecular (C2-8) weight olefins and a relatively low proportion of high molecular weight (C30+) waxes. The product from the first stage is fed into the second stage where the chain growth probabilities are relatively high. The wax and other paraffins produced in the first reaction are largely inert under these conditions. The light olefins compete with heavier olefins for chain initiation, and fewer chains will be initiated at C20+. With most chains initiated at C2-8, moderate chain growth probability will produce a relatively larger fraction in the C5-12 range. In this manner, wax yield is minimized.
