Clean Coal Combustion with In situ Impregnated Sol-Gel Sorbent

摘要

To accomplish clean coal conversion, a suitable conversion process must bechosen. A suitable clean coal combustion process is fluidized bed combustion (FBC). FBC has advantages, but the most important for the thesis is that a sorbent for sulfur oxides can be added in situ to the combustor. The process of regenerative desulfurization is considered. A synthetic sorbent must be developed for regenerative desulfurization. The synthetic sorbent should show selective regeneration at 850 C and good attrition resistance. To develop such a sorbent is the objective of the first part of the thesis. The physico-chemical background of the in situ impregnation technique is examined in part II of the thesis.
