Triboelectrostatic Separation of Mineral Matter from Slovakian Coals

V èlánku sú diskutované niektoré technické aspekty triboelektrostatickej separácie a výs-ledky aplikácie tohto postupu pri úprave troch typov uhlia, konkrétne energetického uhlia z Cíg¾a, Handlovej a Novák. Bolo zistené, e úèinnos separácie ve¾mi úzko závisí na druhu separovan uhlia. Prvé výsledky preukázali súvislos medzi úèinnosou separácie obsahom popola v uhlí

An Overview of the U.S. Department of Energys Federal Energy Technology Center

In December 1996, two of the U.S. Department of Energys (DOE) research and development (R&D) centers were consolidated. The Morgantown Energy Technology Center, located in Morgantown, West Virginia, and the Pittsburgh Energy Technology Center, located in Pittsburgh, Pennsylvania, were combined to create the Federal Energy Technology Center, or FETC. FETC is one of the Department of Energys major field organizations reporting to DOEs Office of Fossil Energy. A total of approximately 600 Federal employees and a similar number of support service contractor employees are at the Pittsburgh and Morgantown sites. FETC manages the majority of the U.S. Fossil Energy research and development programs, valued at nearly $920 million in FY 1997

Methanation in catalyst-sprayed tube wall reactors: a review

The design and operation of catalyst-sprayed tube wall reactors for methanation are discussed. Reactor tubes were either coated on the inner surface or on the outer surface with a Raney nickel catalyst. A liquid coolant, which was opposite the catalyst-reactant gas-side, removed the heat of methanation. Catalyst performance, reactor operating conditions, spent catalyst analyses, and other results are presented for five PDU tests
