“…Steam can be easily separated from CO 2 and its flow is captured, compressed and transported for suitable geological storage [28]. However, the presence of CO 2 in the oxy-fuel combustion process alters heat transfer processes and properties, such as ignition temperature and ash characteristics [29,30].…”

Biomass and coal have different physicochemical properties and thermal behavior. During the co-combustion of coal-biomass mixtures, their thermal behavior varies according to the percentage of each fuel in the mixture. Thereby, this research aims to characterize the thermal behavior of mixtures of coal, sugarcane bagasse, and biomass sorghum bagasse as biomass in simulated combustion (O 2 /N 2) and oxy-fuel combustion (O 2 /CO 2) environments. Experiments have been performed in duplicate on a thermogravimetric analyzer at heating rate of 10 C/min. A uniform granulometry was considered for all materials (63 mm) in order to ensure a homogeneous mixture. Four biomass percentages in the mixture (10, 25, 50 and 75%) have been studied. Based on thermogravimetric (TG) and thermogravimetric (DTG) analyses, parameters such as combustion index, synergism, and activation energy have been determined, as well as the combustion environment influence on these parameters. The results indicate that, although sugarcane bagasse has the lowest activation energy, the thermal behavior of both types of biomass is similar. Thus, biomass sorghum bagasse can be used as an alternative biomass to supply the power required during sugarcane off-season. For both mixtures, optimal results were obtained at 25% of biomass. By analyzing the environment influence on combustion behavior, the results indicate that when N 2 is replaced with CO 2 , it is observed an increase in reaction reactivity, a higher oxidation rate of materials and an improvement in evaluated parameters.

“…L opez et al [30] studied the thermal behavior of mixtures of four types of biomass in an oxy-fuel combustion environment by means of the TGA. The results demonstrated that the oxy-fuel combustion environment can either reduce or increase the activation energy of the reaction, depending on the physical-chemical composition of biomass.…”

“…On the other hand, several thermogravimetric analyses have been conducted to study the feasibility of employing biomass in oxy-turbine cycles. These studies suggest the possibility of using several biological feedstocks such as forest residues (e.g., from poplar and switchgrass), agricultural residues (e.g., corn stover, sugarcane bagasse, pine sawdust, torrefied pine sawdust and olive pits) and waste (e.g., MSW, sewage sludge and slurry) [41,42].…”

In recent years there has been growing concern about greenhouse gas emissions (particularly CO2 emissions) and global warming. Oxyfuel combustion is one of the key technologies for tackling CO2 emissions in the power industry and reducing their contribution to global warming. The technology involves burning fuel with high-purity oxygen to generate mainly CO2 and steam, enabling easy CO2 separation from the flue gases by steam condensation. In fact, 100% CO2 capture and near-zero NOx emissions can be achieved with this technology.This study examines nineteen different oxy-turbine cycles, identifying the main parameters regarding their operation and development. It also analyses the use of advanced natural gas combustion cycles from the point of view of the carbon capture and storage (CCS) and considering political, legislative and social aspects of deploying this technology. Six oxy-turbine cycles which are at the most advanced stages of development (NetPower, CES, Modified Graz, E-MATIANT, AZEP100% and SCOC-CC), were chosen to conduct a Political, Environmental, Social, Technological, Legislative and Economic (PESTLE) risk analysis. This compares each technology with a conventional combined cycle gas turbine (CCGT) power plant without carbon capture as the base-case scenario. Overall, the net efficiency of the different oxy-turbine cycles ranges between 43.6% and 65%, comparable to a CCGT power plant, while providing the extra benefits of CO2 capture and lower emissions.A multi-criteria analysis carried out using DECERNS (Decision Evaluation in Complex Risk Network Systems) software determined that, depending on the specific criterion considered, one can draw different conclusions. However, in terms of technology, environment and social opinion, the most promising cycles are the NetPower and CES cycles, whereas from an economic point of view, E-MATIANT is more competitive in the energy market. Giving each factor equal importance, the NetPower cycle must be considered to be the best oxy-turbine cycle based on our analysis.Most of the oxy-turbine cycles are still under development and only a few cycles (e.g., CES and NetPower) are progressing to the demonstration phase. In consequence, political measures such as CO2 tax and emission allowances need to be implemented for oxy-turbine technologies to become the preferred option for fossil fuel power plants burning natural gas.

“…Direct use of such oils is not recommended because of its excessively high viscosity, e.g., the viscosity of rapeseed oil produced in large amounts in Poland is 10 times higher than that of petroleum‐origin diesel. Another drawback of vegetable oils as a fuel is their thermal instability, which leads to the formation of carbon deposits in motor vehicle engines, and on top of that, the high density of such oils makes them difficult to spray (Kloprogge et al, ; Kowalewicz and Wojtyniak, ; Lopez et al, ; Ma and Hanna, ). That is why, prior to using vegetable oils as fuel, they should be modified first to reduce their viscosity.…”

The aim of this work is to evaluate analytical tools for fast assessment of the catalysts' ability to conduct a catalytic cracking process with the use of vegetable oils. The practical context of the presented concept relates to the use of cracking reaction products as valuable chemical raw materials. The proposed analytical tools allow for quick assessment of reaction products, indication of the molecular weight range, or the presence of specific functional groups. We want to emphasize that vegetable oils can not only be raw products for biofuels but also an alternative to petrochemicals. The study was undertaken to determine the influence of acid-base properties of catalysts on the rapeseed oil conversion process at 500 C. The effect of these properties on the character of the process and quality of the products obtained was shown to be very high. Basic correlations between the formation of coke, gaseous products and dehydrogenation products, and acid-base parameters of the individual catalysts have been observed. The use of spectroscopic methods (FTIR -Fourier Transform Infrared Spectroscopy, 1 H NMR -Nuclear Magnetic Resonance) for fast qualitative analysis of the products is described.
