This book was released on 1992 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact on iron Fischer-Tropsch catalysts of the variables controlling the initial precipitation, subsequent aging and drying conditions have been detailed. Heat treatment of iron oxyhydroxides results in decreasing the surface area and increasing the major pore size as temperature increases, both in air and in an inert atmosphere. A shift toward higher temperature stability is seen for the same iron oxyhydroxide when co-precipitated with 6% Al2O3, SiO2, or ZrO2. Samples for characterization have been withdrawn from the reactor at increasing time intervals during pretreatment and exposure to synthesis gas. Surface area decrease and pore size increase are also observed during reaction pretreatment with CO at 260°C and 100 psi. and during the initial days of reaction under CO/H2. The major changes appear to occur during pretreatment and in the very early stages of the reaction. The effects of added promoter(s) also impact the area and/or porosity of the materials. The area and pore size distributions have shown systematic changes during increasing exposure to synthesis gas.

This book was released on 1996 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The affect of copper promotion on the activity and selectivity of hydrogen pretreated, precipitated iron Fischer-Tropsch catalysts was studied. Fischer-Tropsch synthesis was carried out in the slurry phase in one in one liter continuous stirred tank reactors at a space velocity of 3.lNL h−1 g−1(Fe), H2:CO = 0.7 at either 270°C or 230°C. Catalysts with atomic compositions relative to iron of 10OFe/4.4Si/l. OK and 10OFe/4.4Si/2.6Cu/l. OK were used at 270°C and catalysts with the compositions of 100Fe/4.4Si/4.2K and 10OFe/4.4Si/2.6Cu/4.2K were used at 230°C. XRD and Moessbauer spectroscopy both show that the 10OFe/4.4Si/2.6Cu/l. OK catalyst contained approximately 24% [alpha]-Fe with the remainder Fe3O4 after a 24 h pretreatment with hydrogen at 220°C. Copper promotion was found to substantially increase the activity and productivity of the catalysts. Catalysts promoted with copper reached maximum activity within 100 h of synthesis while catalysts with no copper went through an induction period. The activity of the hydrogen pretreated 10OFe/4.4Si/2.6Cu/1.0K catalyst operated at 270°C was comparable to the activity of the the 100Fe/4.4Si/l. OK catalyst after pretreatment with carbon monoxide or syngas at one atmosphere pressure. However, the activity of the hydrogen pretreated 1O0Fe/4.4Si/2.6Cu/4.2K catalyst at 230°C was found to be substantially lower than the same catalyst pretreated with carbon monoxide or syngas at one atmosphere pressure.

This book was released on 1995 with total page 30 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 {open_quotes}standard-catalyst{close_quotes} 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.
