When creating a new production method for fuel, it is vital to have a reliable means of verifying the quality of the end products. Professor Ramke quickly realized that the standard analytical methods for waste management would not be sufficient for the HTC approach.
Initially, the team tried to assess the end products by evaluating their water content, ignition loss, total organic carbon (TOC) content and calorific value, but this did not provide the information they needed about the effectiveness of the carbonization process. As such, the team chose to analyze CHNS (carbon, hydrogen, nitrogen and sulfur) with a vario MACRO, predecessor model of the vario MACRO cube, to deliver better insights.
With the vario MACRO, they were able to accurately measure changes in hydrogen/carbon and oxygen/carbon ratios. This offered the proof the researchers needed that their HTC method was successfully enhancing the carbon content and energy density - and therefore the calorific content of the final biochar product, while also effectively separating the water and CO2 content.
Finally, the team employed our liquiTOC, predecessor model that uses the same temperature ramping principle than the soli TOC® cube to provide further insights and information about the organic carbon content of the biochar, offering an additional means of affirming the quality of the final product.
