“…Table 6 summarises the chemical composition of the organic fractions derived from the pyrolysis, co-pyrolysis, and catalytic co-pyrolysis processes. The chemical composition of the organic fraction obtained after the GS pyrolysis was composed mainly of oxygenated compounds (phenols, esters, fatty acids, aromatics, ketones, cyclic hydrocarbons, olefins, and other oxygenated compounds) [59,60]. It should be pointed out that these compounds were already identified in previous work as the main oxygenated compounds in the organic fraction of the bio-oil obtained from the pyrolysis of grape seeds [24,30].…”

The catalytic co-pyrolysis of grape seeds and waste tyres for the production of high-quality bio-oils was studied in a pilot-scale Auger reactor using different low-cost Ca-based catalysts. All the products of the process (solid, liquid, and gas) were comprehensively analysed. The results demonstrate that this upgrading strategy is suitable for the production of better-quality bio-oils with major potential for use as drop-in fuels. Although very good results were obtained regardless of the nature of the Ca-based catalyst, the best results were achieved using a high-purity CaO obtained from the calcination of natural limestone at 900 °C. Specifically, by adding 20 wt% waste tyres and using a feedstock to CaO mass ratio of 2:1, a practically deoxygenated bio-oil (0.5 wt% of oxygen content) was obtained with a significant heating value of 41.7 MJ/kg, confirming its potential for use in energy applications. The total basicity of the catalyst and the presence of a pure CaO crystalline phase with marginal impurities seem to be key parameters facilitating the prevalence of aromatisation and hydrodeoxygenation routes over the de-acidification and deoxygenation of the vapours through ketonisation and esterification reactions, leading to a highly aromatic biofuel. In addition, owing to the CO2-capture effect inherent to these catalysts, a more environmentally friendly gas product was produced, comprising H2 and CH4 as the main components.

<p>En la actualidad el aprovechamiento de energía de la biomasa es una alternativa para el impulso de matriz energética renovable. Una de las principales fuentes de biomasa son los residuos orgánicos generados por las actividades productivas y cotidianas. Por lo que existen diferentes mecanismos para valorización energéticas como tratamientos biológicos y termoquímicos. Debido a ello, la presente revisión se centra en las tecnologías termoquímicas, en especial en la pirólisis, ya que con este proceso se puede transformar todo tipo de residuos orgánicos, obteniendo productos principales como los bio-aceites, biochares y gases condensables que tienen un alto valor energético, que pueden ser aprovechados en los sistemas de calefacción y generación de electricidad, entre otras aplicaciones. Para obtener cada uno de los productos y aplicaciones dependerá del tipo de pirólisis y el reactor pirolítico. Estos son seleccionados de acuerdo a la composición de la biomasa a procesar. En definitiva, la pirólisis es una tecnología amigable con el medio ambiente debido a que se desarrolla en ausencia de oxígeno y no genera la emisión de gases de efecto invernadero causantes del cambio climático, además que, el biochar, producto de la pirólisis, ha despertado gran interés desde el punto de vista energético y remediación ambiental por la comunidad científica.</p>

“…However, a drastic increase in demand for power is required to develop new combustion and fuel technologies to meet demand. It is further addressed that pollutants such as HC, CO, NOx, smoke and other particulate matter (PM) emitted at the end of the combustion cycle are very harmful to human life [2]. A number of experiments have been performed using alternative fuels and fuel additives to improve efficiency and reduce emissions [3].…”

This study presents the optimization of the intake manifold and the optimized flow rate of the acetylene gas which acts as a low reactivity fuel to achieve the superior performance and emission characteristics used in the Reactivity controlled compression ignition (RCCI) engine. Intake manifold is one of the engine components which are an important factor in determining the quality of combustion. A very recent evolution of the RCCI engine using the low temperature combustion technique requires a low reactivity fuel which is injected through the secondary fuel injector. The secondary fuel injector must be designed and optimized to allow the acetylene gas to maximize the engine performance and the amount of acetylene gas in liters per minute required for better combustion. If the secondary fuel injector is mounted apart from the critical point, then the performance of the RCCI engine may be poor and also if the acetylene gas is not supplied properly, there is a risk of poor combustion and also if the acetylene gas is supplied excessively, there is a risk of knocking along with the backfire due to the excess fuel charge accumulation during the combustion process. Physical testing of the secondary fuel injector in the intake manifold with different angles, distance and flow rate of supply of acetylene gas is time and cost consuming process. To mitigate this issue optimization is done through computational fluid dynamics principles comes in handy to minimize time and money. In our study, ANSYS-FLUENT software is used for simulation purposes. Optimization of acetylene gas injector distance is carried out by analyzing the pressure contours at the entrance of the combustion chamber. The optimized flow rate of acetylene gas and the injector inclination is found by analyzing the flow contours of turbulent kinetic energy and turbulent dissipation rate.
