Book excerpt: Objective is to develop producing active, stable iron Fischer-Tropsch catalysts for use in slurry-phase synthesis reactors and to synthesize such catalysts on a large scale for process development and long-term testing in slurry bubble-column reactors. A mixed oxalate of Fe, Cu, and K was prepared; a catalyst will be prepared from this material. An evaluation run was performed on an Fe-based UCI catalyst, which was shown to produce low levels of C1 and C2 paraffins; e.g., at the end of the run, when the catalyst was converting 60% of the CO, the C1 and C2 paraffin selectivities were 4.2 and 1.0, respectively.

Book excerpt: The preparation of binderless iron oxide spheres has been achieved by a novel sol-gel forming procedure. The starting material is a solution of iron (III) 2-ethylhexanoate in mineral spirits. This solution is added dropwise to an ammoniacal solution of methanol. The low viscosity of the methanol causes the formation of small droplets of the iron solution. The immiscibility of the mineral spirit solution in the methanol and the difference in surface tensions cause the droplets to assume a spherical shape. The presence of ammonia and water at low levels in the methanol promotes the hydrolysis of the iron (III) 2-ethylhexanoate, which causes the spherical particles to harden. The iron-containing spheres can then be isolated by filtration. These spheres are the first ones reported to be made of 100% iron oxide and prepared without a binder. In the initial preparations, the spheres are 100 to 200?m in diameter. Some problems remain to be resolved with this new method of preparation.

This book was released on 1996 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research project is to develop the technology for the production of physically robust iron-based Fischer-Tropsch catalysts that have suitable activity, selectivity and stability to be used in the slurry phase synthesis reactor development. The catalysts that are developed shall be suitable for testing in the Advanced Fuels Development Facility at LaPorte, Texas, to produce either low- or high-alpha product distributions. Previous work by the offeror has produced a catalyst formulation that is 1.5 times as active as the ''standard-catalyst'' developed by German workers for slurry phase synthesis. The proposed work will optimize the catalyst composition and pretreatment operation for this low-alpha catalyst. In parallel, work will be conducted to design a high-alpha iron catalyst this is suitable for slurry phase synthesis. Studies will be conducted to define the chemical phases present at various stages of the pretreatment and synthesis stages and to define the course of these changes. The oxidation/reduction cycles that are anticipated to occur in large, commercial reactors will be studied at the laboratory scale. Catalyst performance will be determined for catalysts synthesized in this program for activity, selectivity and aging characteristics. The research is divided into four major topical areas: (a) catalyst preparation and characterization, (b) product characterization, (c) reactor operations, and (d) data assessment. Accomplishments to date are described.
