Накратко на български

Химичните процеси при бързото термично разлагане на биомаса се проучват чрез проследяване на въглеродни атоми в целулозата и лигнина. Това помага да се разбере как съставът на растенията влияе върху качеството на произведеното биогориво.

Biopolymers 13C tracking during fast pyrolysis of biomass-A 2-level mechanistic investigation

To reduce the large consumption of fossil resources that have contributed to climate change, Pyrochem has proposed to investigate the fundamentals of biomass fast pyrolysis, a technology that allows production of advanced biofuels. It has long been demonstrated that plant biomass is efficiently converted into liquids via fast pyrolysis. The mixture of aerosols/vapours is then rapidly quenched resulting in a relatively high yield of bio-oil. In addition to the yield, the distribution of products determines the quality of bio-oils, which critically depends on biomass type and temperature-time history. Despite the great added value of fast pyrolysis bio-oil, their application as transport fuels remains limited. Indeed, the pyrolytic liquid is a complex mixture of reactive organic compounds which properties are difficult to control. The relative proportions of cellulose, hemicelluloses and lignin in biomass feedstocks directly influence the chemical reactivity of biomass and have a significant impact on the composition of the bio-oil and its properties. While it is still difficult to predict how the lignocellulosic distribution impacts fast pyrolysis throughputs and the quality of its products, further insight in pyrolysis chemistry is required to (i) reveal key mechanistic details of the formation of bio-oil and (ii) precise the impact of the interactions between lignocellulosic biopolymers on bio-oil's quality.

Цел на проекта

The Marie Skłodowska-Curie Actions (MCSA) proposal is the opportunity for Dr. Marion Carrier to reach a new level of understanding of fast pyrolysis mechanisms and improve the process and design of reactors by acquiring the necessary knowledge at a molecular-level and training using fractionation and isotopic characterization techniques, practical experience on micro-reactors and on larger scale laboratory reactors. It is proposed to use an integrated experimental and computational approach to provide molecular-level insights into pyrolysis chemistry by following the fate of 13C labelled lignocellulosic biopolymers, and subsequently to elucidate the main chemical events during the conversion of biomass. Empirical and mechanistic models will be combined to suggest a new kinetic model of fast pyrolysis. The thermal behaviour of individual unlabelled and labelled biopolymer carefully extracted will be investigated under controlled kinetic regime. The delineation and quantification of primary and secondary reactions will be achieved via the development of new devices for the collection of organic volatiles and via the implementation of spectrophotometric and spectrometric methods. For this, a combination of strong interdisciplinary expertise in several fields such as biopolymer chemistry, thermochemistry, aerosols trapping device fabrication, characterization of gas, liquid and solid products using spectrophotometric and spectrometry techniques is required. This multidisciplinary project will facilitate the commercialization of emergent renewable energy technologies such as fast pyrolysis via the optimization of bio-oil yields and quality, which is expected to offer alternative solutions in the co-production of fuels, high-value-added chemicals and energy, the main research activities of European countries members of the International Energy Agency.
