Abstract:

In this paper a neww approach, consisting of hydrothermal carbonization in combination with gasification in an entrained-flow pprocess for combined heat and power in a gas engine iis investigated. Main advantage of such a system are the l low consumption costs resulting from the type of applicable feeding materials that are not usable with state of the art te echnologies. In the first part a highly integrated plant for the production of biocoal with hydrothermal carbonization is investigated with a plant size of 16 MW of biocoal produ uction. The process is modeled in Aspen Plus® in order to o determine energy and material flows as well as to optimiz ze the heat integration of the system. The decentralized uti ilization of biocoal from hydrothermal carbonization in an e entrained-flow gasifier is simulated for a plant size of 1.6 MMW biocoal input. Efficiencies of the heat and power genera ation are calculated for individual components and the who ole process chain. Power can be produced with an overall electric efficiency of 26 %.
