Biogenic Fuels and Renewable Energies – A Challenge for Elemental Analysis?

Renewable raw materials are becoming increasingly important. This is not only because of the knowledge that natural resources such as crude oil, natural gas and coal will become more scarce over the next few decades, but also as a result of environmental protection (CO2 emission). With the use of biogenic materials for the production of fuels and combustibles, their content of harmful substances is particularly important. The most important of these substances are nitrogen, sulphur and chlorinecontaining hydrocarbon compounds. They not only have a negative effect on the further processing procedure, for example, through the formation of undesired by-products or the contamination of catalysts, they also have a subsequent detrimental effect on the performance characteristics and applications of the finished products. Because of this, a precise inspection of the used raw materials, intermediate stages, and end products is required
