Shell coal gasification project: Gasification of eleven diverse feeds

This report describes the gasification of the following feedstocks in the Shell Coal Gasification Process at SCGP-1: Texas Lignite, Pile County-washed, Pike County-run-of-mine, Dotiki, Newlands, El Cerrejon, Skyline, Robinson Creek, R F, Pocahontas No. 3, and Petroleum Coke. These results demonstrate the unique flexibility of the Shell Coal Gasification Process in handling a wide range of feedstocks with significant differences in moisture content, reactivity, ash content, as viscosity, and calcium, chlorine, and sulfur levels. Process results are presented for each feedstock, including gasifier performance and efficiency calculations. Analytical data, including trace element analyses, are provided for the feedstock, the slag and flyslag solids, and the major gas and liquid streams in the plant.
