PNNL Coal Gasification Research

Description: This report explains the goals of PNNL in relation to coal gasification research. The long-term intent of this effort is to produce a syngas product for use by internal Pacific Northwest National Laboratory (PNNL) researchers in materials, catalysts, and instrumentation development. Future work on the project will focus on improving the reliability and performance of the gasifier, with a goal of continuous operation for 4 hours using coal feedstock. In addition, system modifications to increase operational flexibility and reliability or accommodate other fuel sources that can be used for syngas production could be useful.

Gasification of Chars Produced Under Simulated in situ Processing Conditions Quarterly Report: October-December 1975

Description: This effort is being directed toward support studies for the national endeavor on in situ coal gasification. This task involves the investigation of reaction-controlling variables and product distributions for the gasification of both coals and chars utilizing steam and oxygen. Included in this task is the investigation of the effects of using brackish water as the water supply. The high-pressure char gasification system has been received from the manufacturer and is currently undergoing testing. The types of experiments that would be most useful in their studies have been discussed with two of the three laboratories carrying out field tests of in-situ gasification.

Ceramic Coatings for Components Exposed to Coal-Gas Environments : a Review

Description: The corrosive and erosive environments at high temperatures and pressures in coal gasifiers impose severe requirements on the alloys of fabrication. A concise review of the application of ceramic coatings to resist coal-gas environments has been conducted. The purpose of this review is to explore suitable ceramic or cermet materials that may resist or retard the degradation of metal components and to summarize the state of the art of various methods of producing such coatings.

Theoretical Evaluation of Thermal Imaging for Detection of Erosive Wear of Internally Refractory-Lined Transfer Lines

Description: Infrared scanning has potential use in detecting erosive wear (thickness change) of the refractory surface of large-diameter steel pipes internally lined with refractory concrete, which are typical of those used in coal-conversion processes. An analytical study was conducted to determine the viability of this method. Heat-transfer models were developed to predict surface-temperature distributions on the outer metal surface for various erosive-wear conditions on the inner surface, assuming uniform inner-surface temperature. Variables investigated included thermal conductivity of the refractory concrete, thermal contact resistance between the steel shell and the refractory, outer-surface convective coefficient, outer-surface radiative properties, and refractory-lining thickness and composition. The study used two- and three-dimensional heat-transfer models and various well-defined rectangular cavities on the inner surface. Temperature resolution, and thus calculation of cavity sizes from surface-temperature profiles, is better when the convective coefficient is small and the interfacial contact resistance is uniformly low. The presence of dual refractory-concrete liners using a layer of insulating concrete between the hot-face lining and the steel shell, together with thick steel (t > 25 mm), tends to smear temperature patterns and reduce the temperature gradient so that calculation of cavity shapes becomes impractical.

Production of mild gasification coproducts

Description: In summary, the co-product production runs performed by the SGI Development Center yielded sufficient simulated PDF (process derived fuel) and CDL (coal derived liquid) to meet the production needs for each of the four coals. The LFC Process appears to be an attractive method for upgrading all of the coals except for the Knife River Coal because of its limited yield and difficulty in processing. The Buckskin coal appears to be a slightly stronger candidate for upgrading than the other three coals because it has the greatest CDL yield and a more than 50% increase in heating value from ROM to PDF. (LFC processing of Usibelli and Sarpy Creek coal produces more PDF, but the heating value increase is less and the oil yields are low. Processing Knife River coal produces much less PDF but a greater heating value increase because of its higher moisture content). Finally, in all cases, the LFC Process removed significant percentage of the organic sulfur, clearly demonstrating its coal cleaning potential.

Nondestructive-Evaluation Needs for Coal Liquefaction

Description: Nondestructive-evaluation (NDE) needs for coal liquefaction have been identified by acquiring information from site visits, a literature review, and discussions with government personnel. Nondestructive evaluation has been highly rated in importance as a way to help alleviate problems in coal-conversion systems. The primary problems are associated with highly erosive and corrosive slurries being transferred throughout the coal-conversion process. Applicable NDE techniques for both pre-service and in-service inspection include high-temperature ultrasonics, acoustic emission, radiography, acoustic holography, and ultrasonic spectroscopy.

Development of an advanced continuous mild gasification process for the production of coproducts. Task 4, Mild gasification tests

Description: Western Research Institute (WRI) teamed with the AMAX Research and Development Center and Riley Stoker Corporation on Development of an Advanced, Continuous Mild-Gasification Process for the Production of Coproducts under contract DE-AC21-87MC24268 with the Morgantown Energy Technology of the US Department of Energy. The strategy for this project is to produce electrode binder pitch and diesel fuel blending stock by mild gasification of Wyodak coal. The char is upgraded to produce anode-grade carbon, carbon black, and activated carbon. This report describes results of mild-gasification tests conducted by WRI. Char upgrading tests conducted by AMAX will be described in a separate report.

Commissioning an Engineering Scale Coal Gasifier

Description: This report explains the development, commissioning, and testing of an engineering scale slagging coal gasifier at PNNL. The initial objective of this project was to commission the gasifier with zero safety incidents. The commissioning work was primarily an empirical study that required an engineering design approach. After bringing the gasifier on-line, tests were conducted to assess the impact of various operating parameters on the synthesis gas (syngas) product composition. The long-term intent of this project is to produce syngas product for use by internal Pacific Northwest National Laboratory (PNNL) researchers in catalyst, materials, and instrumentation development. Future work on the project will focus on improving the reliability and performance of the gasifier, with a goal of continuous operation for greater than 4 hours using coal feedstock. In addition, alternate designs that allow for increased flexibility regarding the fuel sources that can be used for syngas production is desired. Continued modifications to the fuel feed system will be pursued to address these goals. Alternative feed mechanisms such as a coal/methanol slurry are being considered.

Laboratory Support for in situ Gasification Reaction Kinetics. Quarterly Report, October-December 1976

Description: This work, which is part of the ANL energy program for ERDA, is directed toward studies for the national endeavor on in situ coal gasification. The objective of this work is to determine the reaction-controlling variables and reaction kinetics for gasification of chars resulting when coal is pyrolyzed in underground gasification. The reactions to be studied include steam-char, carbon dioxide-char, hydrogen-char, and water gas shift reaction. Discussed in this report are the effects on the reactivity of chars of pyrolysis in simulated gasification product gas rather than pure nitrogen. In addition, further investigations of the water gas shift reaction and methanation reaction are discussed.
