TL;DR: In this paper, the authors describe the gasification of several coals in the Shell Coal Gasification Process at SCGP-1, including Illinois No. 5, Buckskin, Blacksville No. 2, Pyro No. 9, and Drayton.
Abstract: This report describes the gasification of several coals in the Shell Coal Gasification Process at SCGP-1. This represents a wide variety of coals, including Illinois No. 5 -- the base coal -- Maple Creek, Buckskin, Blacksville No. 2, Pyro No. 9, and Drayton. These results demonstrate the unique flexibility of the Shell Coal Gasification Process in handling a wide range of coals. These coals have significant differences in coal properties, including moisture content, reactivity, ash content, ash viscosity, and calcium, chlorine, and sulfur levels. Process results are presented for each coal, including gasifier performance and efficiency calculations. Analytical data, including trace element analyses, are provided for the feedstock coal, the slag and flyslag solids, and the major gas and liquid streams in the plant. 13 refs., 57 figs., 41 tabs.

TL;DR: The analysis of trapped organic compounds in coals and pyrolysis products analysis of oxidation products is discussed in this paper, which is useful for understanding the chemistry in coal conversion processes and in the search for new methods for converting coal.
Abstract: Publisher Summary This chapter discusses the techniques applied to a variety of problems and used for the study of coals and coal products. Mass spectrometry (MS) is an exceedingly useful analytical tool for the organic chemist. The chapter presents the analysis of trapped organic compounds in coals and pyrolysis products analysis of oxidation products. The identification of the aromatic units indigenous to the coal macromolecules obtained by these selective oxidative degradations is an important step in elucidation of the structures of coals. This information is very useful for understanding the chemistry in coal conversion processes and in the search for new methods for converting coal. The chapter also discusses the determination of aromaticity of coal by fluorination.

TL;DR: In this paper, a well-mixed reactor was developed to study the initial reaction pathways and mechanisms of direct coal liquefaction, where a pulse-injection flow vessel exploits the reactor residence time distribution to obtain an isothermal series of samples of well-defined holding times from 10 to 900 s. The reactor design also allowed for quick and efficient procurement of optimally spaced and sized samples.
Abstract: A well-mixed reactor was developed to study the initial reaction pathways and mechanisms of direct coal liquefaction. This pulse-injection flow vessel exploits the reactor residence time distribution to obtain an isothermal series of samples of well-defined holding times from 10 to 900 s. The reactor design also allowed for quick and efficient procurement of optimally spaced and sized samples. In this paper, operation of this reactor is illustrated using both model compound and coal liquefaction experiments.
