Bituminous Coal Research

Still another process, called BI-GAS, was developed by Bituminous Coal Research in a 73 t/d pilot plant in Homer City, Peimsylvania. In this entrained-bed process, pulverized coal slurry was dried and blown into the second stage of the gasifier to contact 1205°C gases at ca 6.9 MPa (1000 psi) for a few seconds residence time. Unreacted char is separated and recycled to the first stage to react with oxygen and steam at ca 1650°C to produce hot gas and molten slag that is tapped. 

Bi-Gas [Bituminous Gas] A coal gasification process using a two-stage, entrained-flow slagging gasifier. Developed by Bituminous Coal Research. A 120-tons-per-day pilot plant was built in 1976 at Homer City, PA, under sponsorship from the U.S. Energy Research and Development Administration and the American Gas Association.

One of the authors had an opportunity to read the reflectance values of some of the coals of Permian age from Africa, Australia, and South America. These samples were randomly selected to ascertain the nature and types of vitrinoids present. This was possible through the courtesy of the Anthracologi-cal Laboratories of Bituminous Coal Research, Inc. The types of vitrinoids encountered varied from V4 to V , with an abundance of V . In this respect...

Slags were prepared by mixing preweighed amounts of additives and coal ash. The coal ash was obtained from Bituminous Coal Research, Inc. It was prepared by ashing Loveridge Seam, West Virginia coal in air at 750°C, followed by a reduction in a 60%CO-40%C02 gas at 1000°C, then cooled under nitrogen. 

Three associations furnish information on coal. Bituminous Coal Research, Inc., of Washington, D. C., collects data continuously on bituminous coal and coal-consuming equipment, including information on processes, equipment, and new products. Its technical staff is available to members and consumers on problems affecting coal preparation and consumption.
