When burning fossil fuels in energy resources, especially limestones are used in the present technological practice. Some side products from the processing of organic materials contain calcium. No implementation for these materials has up to now been realized and it would be, therefore, advantageous to process these side products, for example as replacement of limestone in the desulfurization process. One of these materials is technical lanolin separated from sheep wool in the process of its purification. This material shows a higher content of calcium in its composition, consequently a possible source for desulfurization of products of combustion from modern fluidized-bed combustors. In this contribution attention is paid to the use of lanolin in desulfurization of products of combustion that means lowering of sulfur oxides from the products of combustion. On an experimental apparatus, it is demonstrated that technical lanolin can be used in the process of desulfurization. (C) 2011 Elsevier B.V. All rights reserved.
