The Combustion and Catalysis Lab is directed by Professor Marco J. Castaldi. The main focus is the thermal and catalytic conversion of carbon based material to desired products. For example, municipal solid waste and biomass to synthetic fuels, liquid fuels to hydrogen and greenhouse gases (carbon-based) to fuels.
A students from Università degli Studi di Perugia, Italy joined the CCL research team in January 2014. Giacomo Rossetti will be completing experiments for his thesis work at CCL in New York City. Giacomo visit is supported by H2CU.
Two Ph.D students from Universidad Autónoma de Nuevo León joined the CCL research team in December 2014. Ladislao Sandoval will be occupying a position at CCNY for 1 year and Carolina Solis for 6 months. Each student has their own respective project dealing with catalysis. More information on their research can be found on their CCL personal webpages.
Flavia Albuquerque joined the CCL group within EEC|CCNY in October 2013, through the WTERT-Brazil connection, as a visiting research assistant and is currently working on a project aimed to understand the impact of different types of fuel on pollutant emissions from cement industry.
Due to high temperatures required in cement kilns, cement industries demand high energy consumption. Most of the energy is still supplied by fossil fuels (mainly coal and petroleum coke), contributing significantly to the production costs, which could be reduced by using alternative fuels with adequate calorific values. In this scenario, refuse derived fuel (RDF) is being widely studied as an alternative fuel and can have a major role in diverting waste currently going to landfill.
Based on the most common fuels in this industry, especially the ones used by those concerned with the environment, a comparison of the pollutants concentrations evolved from the combustion process will be presented, as well as a sensitivity analysis of the influence of the temperatures on emissions and an overall analysis of the kiln and calciner indicating the profile of emissions throughout each unit.
Through experiments with RDF, real data from operating cement plants, Aspen Plus simulation and kinetic modeling based on the GRI mechanism – which was upgraded to consider sulfur and chlorine reactions – this research will provide helpful data in the decision making process in terms of fuel selection for the cement industry.
