An excellent series of papers was offered, covering a wide range of themes in fundamental coal research. Of the 50 papers presented verbally at the conference, the manuscripts of 47 are included in this volume. Records of the discussions of individual papers and of the general discussions are also incorporated. It is hoped that the book will be of interest not only to those concerned in coal research but also to petroleum geochemistry and to those dealing with general geochemical problems.

Humin has been regarded as the most intractable component of SOM. It must be considered to be a very important component, however, because typically it represents more than 50% of the organic carbon in a soil (Kononova, 1966 Stevenson, 1982,1994) and more than 70% of the organic carbon in unlithified sediments (Durand and Nicaise, 1980 Rice, 2001). The definition of humin (Section 1.3.3) is similar to that of a protokerogen (Calvin and Philip, 1976 Rice, 2001), which is often used in petroleum geochemistry to describe insoluble organic matter in unlithified sediments.

A catalytic process is commercially viable if the catalyst transformation is achieved within definite, practical limits of space and time. To quantify this aspect, one can determine the so-called space-time yield. This measure of activity is simply the amount of product obtained per unit time and per unit reaction space (where reaction space is usually the reactor volume). Weisz (79) pointed out that in industry the useful space-time yield is rarely less than 10"6 g/mol of reactant per cubic centimeter of volume of reactor space per second. This has been called the Weisz window on reality. Figure 9 (79) shows the Weisz window and other windows of chemical activity that apply to biochemistry and petroleum geochemistry (79). 

The problem of the origin of the metal-porphyrins is closely related to that of the origin of petroleum and is oie of the most basic and interesting questions of petroleum geochemistry. The most probable conclusion seems to be that the nickel and vanadium porphyrin complexes are formed by metal exchange reactions from animal and/or plant metabolic pigments such as hemoglobin and chlorophyll.

Figure 3 Vitrinite reflectance is used to provide an indication of the maturity of a source rock or potential source rock. The approximate values for the onset of oil generation, peak oil generation, and onset of gas generation are also shown in this diagram. It should he noted that there is some disagreement as to the precise values for these ditferent processes (Hunt, 1996) (reproduced hy permission of Freeman from Petroleum Geochemistry and...
