This book was released on 1994 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this investigation is to evaluate two novel copper-based sorbents, namely copper-chromium and copper-cerium, for their effectiveness in removing hydrogen sulfide from fuel gas in the temperature range of 650° to 850°. Such high temperatures will be required for the new generation of gas turbines (inlet>750°C) in Integrated Gasification Combined Cycle (IGCC) systems. The effect of pre-reduction with H2, in the presence of H2O on the performance of the sorbents in cyclic sulfidation/regeneration, was studied in a thermogravimetric analyzer (TGA) and in a fixed-bed reactor at 750°C. The results of the TGA tests indicate that pre-reduction of the sorbents is very fast in either 10% or 30% H2. Without sorbent pre-reduction, sulfidation consists of two-stages, a reduction-dominating and a sulfidation-dominating stage. Sulfidation apparently takes place before reduction is complete. During regeneration some copper/cerium sulfates may have formed and Cu2O may have formed in addition to CuO. The fixed-bed reactor tests show that at 750°C: (1) prereducing the CuO-Cr2O3 with H2 does not effect the reactivity of the sorbent towards H2S at either the high or low H2 feed gas concentrations and (2) when 30% H2 was used during sulfidation of either sorbent, the first H2S breakthrough occurs earlier than when 10% H2 was used.

Available in PDF, EPUB and Kindle. Book excerpt: Currently, the Morgantown Energy Technology Center, Department of Energy (DOE/METC) is actively investigating alternative hot fuel gas desulfurization sorbents for application to the Integrated Gasification Combined Cycle (IGCC). A sorbent must be highly active towards sulfur at high temperatures and pressures, and under varying degrees of reducing atmospheres. Also, it must regenerate nearly ideally to maintain activity over numerous cycles. Furthermore, regeneration must yield a sulfur product which is economically recoverable directly or indirectly. Several metal oxides have been investigated as regenerable sorbents for the removal of hydrogen sulfide (the primary sulfur bearing compound) from hot fuel gases. MnO was shown to have an intrinsic reaction rate approximately one order of magnitude greater than the rate or reaction with either CaO or ZnO and two orders of magnitude greater than the reaction rate with V203. Manganese also shows desulfurization potential in the temperature range of 600-700°C where metal oxides currently known to be reactive with H2S are unsatisfactorily. In response to stability difficulties of single and binary metal oxide sorbents, increasing effort is being directed towards incorporation of an inert component into sorbent formulation as witnessed by the various Zn-titanates. Primarily, the inert component increases pore structure integrity while stabilizing the active metal oxide against reduction. This report will address testing of Mn-based sorbents in an ambient pressure fixed-bed reactor. Steady-state H2S concentrations and breakthrough times will be presented.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides extensive information on high-temperature H2S removal for integrated gasification combined cycle (IGCC) coarse gas, together with briefly introductions to the concept of clean coal technology, and to the mechanism and kinetics of hot coal gas desulfurizers. Readers will gain a comprehensive understanding of available control methods for high-temperature H2S removal in IGCC coarse gas and how the technology has been adopted by industry. As such, the book offers a unique resource for researchers and engineers in the fields of energy science and technology, environmental science and technology, and chemical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: This contract focuses on the development of sorbents and processes for removal of H2S from hot coal gas with the product of sorbent regeneration being elemental sulfur. TDA Research's process uses a regenerable tin(IV) oxide-based (SnO2) sorbent as the first sorbent and zinc ferrite (or zinc titanate) as a second sorbent.

Available in PDF, EPUB and Kindle. Book excerpt: Economic and environmental requirements for advanced power generating systems demand the removal of corrosive and other sulfurous compounds from hot coal gas. After a brief account of the world energy resources and an overview of clean coal technologies, a review of regenerable metal oxide sorbents for cleaning the hot gas is provided. Zinc oxide, copper oxide, calcium oxide, manganese oxide based as well as supported and mixed metal oxide sorbents are treated. Performance analysis of these sorbents, effects of various parameters on the desulfurization efficiency, kinetics of sulfidation and regeneration reactions, sulfiding and regeneration mechanisms are discussed. Two chapters present recent results in the direct production of elemental sulfur from regeneration or SO2-rich gases.
