The Physical And Petrographic Characteristics Of Formcoke Produced Experimentally From Lignite And Subbituminous Coal, Bruce L. Ramsey
Theses and Dissertations
Formcoke was produced experimentally from a North Dakota lignite and a Wyoming subbituminous coal. The effect of initial charring tem perature (600°C or 900°C), of char grain size (less than 18 mesh, less than 35 mesh, or less than 60 mesh), of briquetting pressure (1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000 or 10,000 psi) of binder percentage (5, 10, 15, 20 or 25 per cent), and of final carbonization heating rate (18°C/:min, 12°C/min or 6°C/min) on formcoke briquet com pressive strength was studied.
A final carbonization heating rate of 6°C/min produced uniform shape briquets. Rates of 12°C/min and …
