The Basic Characteristics of Gasification Slag from Texaco Gasifier and Shell Gasifier

Abstract:

Gasification slag is one of the solid wastes forming by water-granulation for molten liquid and residual carbon. In this paper, the basic characteristics of gasification slags from Texaco and Shell gasifier (termed as WH and QP, respectively) were studied. X-ray fluorescence (XRF), X-ray diffraction (XRD), optical microscope (OM), and scanning electron microscopy (SEM) were carried to investigate the chemical composition, phase constituents, petrographical structure and microstructure of the slag, respectively. The results showed that: (1) The main chemical composition of WH and QP is SiO₂, Al₂O₃ and CaO. In addition, a large amount of residual carbon is also existed in WH. (2) The main phases of WH and QP are vitreous glass and quartz. In addition, calcite is also detected in WH; (3) The microstructural features of the two slags are nearly the same. Residual carbon in WH is existed with laminar structure.
