Thermal pretreatment of low-ranked coal for control of mercury emissions

Autor: F.D Guffey, A.E Bland

Publikováno v: Fuel Processing Technology. 85:521-531

The Environmental Protection Agency (EPA), under the requirements of the Clean Air Acts Amendments (Public Law 101-549), evaluated the hazardous air pollutants emitted by coal-fired power plants. In December 1997 and February 1998, they reported thei

Reactive coprocessing of scrap tires and heavy oil

Autor: F.D. Guffey, C.Y. Cha, Sanjay Saraf, John A. Marsh

Publikováno v: Resources, Conservation and Recycling. 13:1-13

The reactive coprocessing of scrap tires and heavy oil was carried out at temperatures of 375, 400, 425, and 450°C. The ultimate yields from the following process cases were determined: scrap tires without oil, SAE 50 weight oil without scrap tire,

PYROLYSIS OF WASTE POLYSTYRENE IN HEAVY OIL

Autor: F.D. Guffey, C.Y. Cha, John A. Marsh

Publikováno v: Chemical Engineering Communications. 129:69-78

Waste plastics are an environmental problem because of recycling limitations and their resistance to natural decomposition. This research investigates the thermal degradation (pyrolysis) of waste polystyrene in heavy oil as a tertiary recycling metho

Investigations into coal coprocessing and coal liquefaction

Autor: Tiejun Zhang, F.D. Guffey, F.P. Miknis, H.W. Haynes, K.P. Thomas, D.A. Netzel

The conversion of coal to liquid suitable as feedstock to a petroleum refinery is dependent upon several process variables. These variables include temperature, pressure, coal rank, catalyst type, nature of the feed to the reactor, type of process, e
