GFEDBASE - A pure substance trace element thermochemical database

In order to investigate the fate of several trace elements in thermal coal conversion, a computer program, MINGTSYS, and a database, GFEDBASE, have been developed. The program minimizes the total Gibbs energy of a multiphase and multicomponent mass balance constrainted system. The program and major results performed with it have been described elsewhere, see Frandsen et al. (1993, 1994). The database contains pure substances thermochemical data for approximately 600 chemical species of the trace elements: As, B, Be, Cd, Co, Cr, Ga, Ge, Hg, Ni, P, Pb, Sb, Se, Sn, V and Zn. In this paper, the content of the database, GFEDBASE, is given in an easy-to-use format together with a list of data sources.
