ECN has a long history in gasification. Back in the 80’s and 90’s, ECN focused on pressurized entrained flow gasification and fixed bed gasification (downdraft) for coal. In the early 90’s biomass and waste became more prominent at ECN and a circulating fluidized bed gasifier as well as a bubbling fluidized bed gasifier were constructed. In 2004, the development program for an indirect gasifier started, called MILENA [1]. All these R&D programs had their own drivers. The MILENA development is based on the learning’s from the CFB gasification process. A CFB is fuel flexible, but does not have the 100% fuel conversion, has problems with agglomeration due to char accumulation and the gas produced is of a low calorific value. The MILENA development is the solution for these issues and provides new routes for the producer gas utilization, such as chemicals and fuels production. This paper will outline the flexibility of MILENA and will focus on one aspect in particular, namely different feedstock application.
