Enhanced durability and reactivity for zinc ferrite desulfurization sorbent

Description: AMAX Research Development Center (AMAX R D) has been investigating methods for enhancing the reactivity and durability of the zinc ferrite desulfurization sorbent. Zinc ferrite sorbents are intended for use in desulfurization of hot coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. For the present program, the reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point and at saturation in a bench-… more

Pyrolysis and gasification of coal at high temperatures

Description: Coals of different ranks will be pyrolyzed in a microscope hot-stage reactor using inert and reacting atmosphere. The macropore structure of the produced chars will be characterized using video microscopy and digital image processing techniques to obtain pore size distributions. Comparative studies will quantify the effect of pyrolysis conditions (heating rates, final heat treatment temperatures, particle size and inert or reacting atmosphere) on the pore structure of the devolatilized chars.

Thermal/chemical degradation of ceramic cross-flow filter materials

Description: This report summarizes the 14-month, Phase 1 effort conducted by Westinghouse on the Thermal/Chemical Degradation of Ceramic Cross-Flow Filter Materials program. In Phase 1 expected filter process conditions were identified for a fixed-bed, fluid-bed, and entrained-bed gasification, direct coal fired turbine, and pressurized fluidized-bed combustion system. Ceramic cross-flow filter materials were also selected, procured, and subjected to chemical and physical characterization. The stability of… more

A novel approach to highly dispersing catalytic materials in coal for gasification

Description: This project seeks to develop a technique, based on coal surface properties, for highly dispersing catalysts in coal for gasification and to investigate the potential of using potassium carbonate and calcium acetate mixtures as catalysts for coal gasification. The lower cost and high catalytic activity of the latter compound will produce economic benefits by reducing the amount of K{sub 2}CO{sub 3} required for high coal char reactivities. The work is focused on the elucidation of coal-catalyst… more

Yttria-stabilized zirconia solid oxide electrolyte fuel cells, monolithic solid oxide fuel cells. Quarterly report, July--September 1989

Description: The MSOFC features of thin ceramic components, small cell size, and 1000{degree}C operating temperature combine to provide very high power densities of about 8 kW/kg or 4 kW/L for the MSOFC (fuel cell only, coflow version). This very high power density coupled with expected efficiencies of over 50 percent offers the possibility of successful competition with existing electrical generation systems. The ability of the MSOFC to reform hydrocarbon fuels within the fuel channels allows existing fuel… more

Performance evaluation of a ceramic cross-flow filter on a bench-scale coal gasifier

Description: The ceramic cross-flow filter (CXF) system is a promising method to be used in advanced coal based power systems for high temperature, high pressure (HTHP) particle removal. Using a subpilot scale pressurized fluid-bed combustor (PFBC) at Argonne National Laboratory and various PFBC simulators, prior projects have indicated that CXF systems can be used in oxidizing environments at PFBC conditions. To extend the use of CXF systems, this project completed an economic analysis comparing the cost o… more
