Pyrolysis and gasification of coal at high temperatures

Description: The macropore structure of chars is a major factor in determining their reactivity during the gasification stage. The major objectives of this contract were to (a) quantify by direct measurements the effect of pyrolysis conditions of the macropore structure, and (b) establish how the macropores affected the reactivity pattern, the ignition behavior and the fragmentation of the char particles during gasification in the regime of strong diffusional limitations. Results from this project provide m… more

DC CICC Retrofit Magnet Preliminary Design, Software Development and Analysis Report

Description: The proposed retrofit coil is made of superconducting Cable-in-Conduit Conductor (CICC). The coils are designed to produce a nominal vertical field of 4.5 tesla within the MHD channel based on a nominal current density of 13.05 MA/m{sup 2}. The coils are supported within a case, or so-called constant tension strap. When the magnet is energized, the electromagnetic J {times} B body forces push the winding pack laterally outward and vertically towards the machine's midplane, thus putting the stra… 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 higher 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. As was shown in previous reports, coal loading with p… more

Methyl chloride via oxyhydrochlorination of methane

Description: Purpose of this contract is to develop a process for converting light alkane gases to methyl chloride via oxyhydrochlorination using highly selective, stable catalysts (Cu) in either fixed-bed or fluid-bed reactors. Catalyst development and micro-packed bed screening studies are underway. Engineering support for pre-design on the miniplant is struggling with the unit operations problem associated with separation of products from unreacted methane.
