In this comprehensive analysis of Chile’s air quality dynamics spanning 2016 to 2021, the utilization data from National Air Quality Information System (SINCA) and its network monitoring stations was undertaken. Quintero, Puchuncaví, Coyhaique were focal points study, with primary objective being construction predictive models for sulfur dioxide (SO 2 ), fine particulate matter (PM 2.5 coarse 10 ). A hybrid forecasting strategy employed, integrating Autoregressive Integrated Moving Average...
This study explores the Hydrothermal Carbonization (HTC) treatment of lignocellulosic biomass blends, delving into influence several key parameters: temperature, additive nature and dosage, residence time, composition. Rapeseeds, Pinus radiata sawdust, oat husks, pressed olive served as studied biomasses. One hundred twenty-eight experiments were conducted to assess effects on mass yield (MY), energy (EY), higher heating value (HHV), final ash content (ASH) by a Factorial Experimental...
Abstract Most developing countries lack sufficient legal and management infrastructure to dispose of urban solid waste (USW). The continuous increase USW generation requires evaluating different treatments for based on the life cycle assessment methodology compare environmental impact by reducing greenhouse gases leachate. Hydrothermal carbonization (HTC) gasification processes are presented as potential solutions treatment due their efficiency in producing energy local requirements. This...
This work evaluates a continuous biomass hydrothermal carbonization process through modeling and steady state simulation using the UniSim Design simulator. The reactive was divided into four stages: hydrolysis, intermediate compounds degradation, aromatics formation, polymerization process, which make it possible to obtain solid product or hydrochar. Pure types their mixtures were compared, considering hydrochar carbon yields, H/C, O/C ratios, deviation from batch process. results of yield...
The effect of magnesium chloride as an additive hydrothermal carbonization (HTC) lignocellulosic biomass (Pinus radiata sawdust) was studied. HTC tests were carried out at fixed conditions temperature and residence time 220 °C 1 h, respectively, varying the dose in range 0.0–1.0 g MgCl2/g biomass. carbonized product (hydrochar) tested order to determine its calorific value (HHV) while using PARR 6100 calorimeter, mass yield by gravimetry, elemental analysis a LECO TruSpec analyzer, volatile...
Hydrothermal carbonization makes it possible to transform lignocellulosic biomass into hydrochar, a carbon-rich material that can be used as fuel. Hydrochar has less calorific value than standard coal but generates ashes during combustion. This study is pre-feasibility analysis carried out evaluate technically-economically and environmentally the use of hydrochar fuel or co-fuel in thermal power plants Chile. Until now there are no reports about it. The proposal this work was replacement...
(1) Background: Phosphates are used in the food industry to improve water retention and product quality. However, when consumed excess, they can be harmful health. Instead, bovine skin gelatin hydrolysates present health benefits such as being a rejuvenating agent, stimulating collagen production, improving quality, addition source of protein. The effect on texture color thermally processed chicken meat (boiled type) antioxidant activity was evaluated. (2) Methods: Hydrolysates were prepared...
Hydrothermal carbonization (HTC) is a thermochemical technology of biomass conversion that has some advantages: lower operating temperature than other technologies, ability to process with high moisture content and generation final product higher calorific value the original hydrophobic characteristics. This study evaluated influence temperature, time, blend, nature dose additive in HTC process. The response variables were mass yield (MY) heating (HHV), generating total 128 experiments...
Wildfires generate large amounts of atmospheric pollutants yearly. The development an emissions inventory for this activity is a challenge today, mainly to perform modeling air quality. There are free available databases with historical information about source. main goal study was process the results biomass burning year 2014 from Global Fire Assimilation System (GFAS). studied were black carbon, organic fine and coarse particulate matter, respectively. inputs pre-formatted enter simulation...
Global population growth and rising consumption levels have significantly increased resource use energy demand, leading to higher greenhouse gas concentrations waste output. As a result, alternative treatment methods for sustainable municipal solid (MSW) management are crucial. This research evaluates the efficiency of integrating hydrothermal carbonization (HTC) gasification an optimized MSW biomass blend. HTC was conducted one hour at 220°C in 5 L reactor, followed by hybrid porous medium...
This study presents the development and application of a mathematical optimization model to improve decision-making in supply chain for high-energy-density pellet (HEDP) production commercialization. Focused on Metropolitan Region Chile, research involved detailed analysis key components, including identifying landfills controlled dumps, waste volume assessments, plant location analysis, technology evaluation, market potential exploration. The revealed that available raw material region was...
