Book excerpt: Bench-scale, mild-temperature fluidized bed gasification (MTFBG) was performed on three high sulfur Illinois basin coals after mixing with phosphoric-acid. The research initiated development of an advanced processing technology which partitions coal sulfur to the gas phase as H2s. The MTFBG experiments were performed on Illinois coals IBC-101, IBC-106 and IBC-110. Product yields were between 60--80% char, 0.41.3% tar and 20--40% gases. Gas yields were sensitive to the coal/acid mixing ratios and the residence time of the coal within the gasifier. Tar and gas yields were significantly lower for coal/acid feeds than for coal-only feeds. At 500°C, the sulfur removal was as high as 82% for IBC-106; sulfur emissions during combustion of this char would be 1.10 lbs SO2/MMBtu. Emission levels from the IBC-110 char would be 1.15 lbs SO2/MMBtu whereas it would be 2.15 lb SO, /MmBtu from the IBC-101 char. In comparison, the emission levels from chars produced during gasification of coal using no acid would be 4.35 (IBC-110) and 4.81 (IBC-101), whereas the emission levels of the parent coals would be between 5--6 lb SO2/MMBtu. Gas product analysis confirmed that the coal sulfur was removed as H2s. Pressurized hot-water filtration of the chars removed nearly 80% of the phosphorus. Its removal rate should be near 95% to restrain the reagent cost to less than $25/Ton of SO2.

Book excerpt: Bench-scale, mild-temperature fluidized bed gasification (MTFBG) of three high sulfur Illinois basin coals (IBC) mixed with phosphoric acid will be performed to initiate development of an advanced processing technology which partitions coal sulfur to the gas phase as H2S. The influence of coal type, coal agglomeration, and steam injection on the properties of the solid, condensible and gaseous products produced during MTFBG will be examined. Analytical measurements of the products will be obtained and are designed to provide product quality and quantity. Combustion reactivity testing of the char, and pressurized, hot water extraction of H3PO4 from the char, will be performed to provide information for design of a continuous and integrated process for the removal and recovery of coal sulfur. During this quarter, the acquisition and construction of equipment to be used for MTFBG of Illinois coals and hot water, pressurized filtration of chars were completed. IBC 106 was subjected to fluidized bed gasification testing under nitrogen and steam/nitrogen atmospheres. The percentage of total sulfur removed from the parent coal using physical cleaning followed by MTFBG of coal/phosphoric acid mixtures was as high as 94% at a gasification temperature of 500°C.

MTFBG experiments were performed on Illinois coals IBC-101, -106 and -110. The yields of char, tar and gaseous products varied between 60--85% char, 0.4--1.3% tar, and 15--43% gas for IBC-101 and -106. Gas yields were sensitive to the coal/phosphoric acid mixing ratio and also dependent on the residence time within the gasifier. The mean residence time was low ((approximately)6 seconds), and was influenced by the mean particle size of the coals. The total sulfur removal was as high as 83% for IBC-106 at a temperature of 500°C. In comparison with previous fixed bed testing, it is believed that the sulfur is removed as H2S. Experiments planned for the next quarter should define the concentration and type of sulfur in the gas.

Download or read book High Temperature Membranes for H2S and SO2 Separations. Quarterly Progress Report, July 1, 1992--September 30, 1992 written by and published by . This book was released on 1992 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: High temperature membrane separation techniques have been applied to gas mixtures involved in coal utilization. For coal gasification, H2S has been removed from the syn-gas stream, split into hydrogen which enriches the syn-gas, and sulfur which can be condensed from an inert gas sweep stream. For coal combustion, SO2 has been separated from the flue gas, with concentrated SO3 produced as a by-product. Both processes appear economically viable but each requires fundamental improvements: both the H2S cell and the SO2 cell require more efficient membranes and the H2S cell needs a more efficient anode. Membranes will be fabricated by either hot-pressing, impregnation of sintered bodies, or tape casting. Research conducted during the present quarter is highlighted, with an emphasis on progress towards these goals.

Quarterly Progress Report, July 1, 1992--September 30, 1992 written by and published by . This book was released on 1992 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method of polishing coal synthesis by electrochemical operation is being perfected. An electrochemical potential gradient is used to remove H2S from the coal gas stream, leaving only H2 to enrich the exiting polished gases. Sulfur byproduct is swept away by an inert sweep gas and later condensed. Current experiments are based on improving selective removal from low initial H2S contents (10 ppm). High flow rate data is also being investigated along with sealing the cell housings. Latest option for consistent removal and seals is Zircar manufactured membranes.

Quarterly Progress Report, January 1, 1992--March 31, 1992 written by and published by . This book was released on 1992 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: An advanced process for the separation of hydrogen sulfide from coal gasification product streams through an electrochemical membrane is being developed. H2S is removed from the syn-gas stream, split into hydrogen, which enriches the syn-gas, and sulfur, which can be condensed from an inert gas sweep stream. The process allows removal of H2S without cooling the gas stream and with negligible pressure loss through the separator. The process is economically attractive by the lack of adsorbents and the lack of a Claus process for sulfur recovery. Research conducted during the present quarter is highlighted, with an emphasis on progress towards the goal of an economically viable H2S removal technology for use in coal gasification facilities providing polished fuel for co-generation coal fired electrical power facilities and Molten Carbonate Fuel Cell electrical power facilities. Polishing application of this technology to coal gasification synthesis gas has been demonstrated with H2S removals as high as 89.1% recorded. No successful runs with stainless steel housings have yet been achieved. However, since stoichiometric CO2 removal with stainless steel housings has been achieved, H2S removal is achievable.

Quarterly Progress Report, January 1, 1993--March 30, 1993 written by and published by . This book was released on 1993 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method of polishing coal synthesis gas by an electrochemical operation is being perfected. The operation which takes advantage of an electrochemical potential gradient rather than conventional techniques, removes poisonous H2S from the coal gas stream leaving only H2 to enrich the exiting flue gases. Sulfur is the by-product which is carried away by an inert sweep gas and condensed downstream. The technology is attractive due to aesthetics as well as economics when compared to other alternatives. Current experiments are focusing on production of selective membranes made of zirconia and improving cell housing seals using Aluminum foil gaskets.
