“…The gasification process can be carried out using various gasification agents: technologies using air or oxygen are usually referred to as autothermal reforming, in this case, the energy for gasification is provided by exothermic partial oxidation of the feedstock (Table 5, reactions 1–5). The use of air as oxidant results in a low calorific value (4–8 MJ/Nm 3 ) of syngas due to its dilution with nitrogen (H. Yang & Chen, 2015). In case if pure oxygen is used, the calorific value of gas is much higher (up to 18 MJ/Nm 3 ) but the oxygen separation process results in additional costs and energy requirements.…”

The paper aims to review the state of the art in the field of pyrolysis and gasification of waste and to identify approaches that can be prospective considering the upcoming transformation of society. The results show that the transition to a circular, low carbon economy will significantly change the composition of municipal wastes, making thermochemical approaches more and more competitive. However, it does not mean that pyrolysis and gasification will outperform incineration in the field of traditional waste to energy. Novel thermochemical waste management approaches must not be viewed as competitors, but rather as the successors of the traditional mass‐burn incineration. The transition to a circular, low carbon economy will result in an emergence of new needs, new products and thus in possibilities of new pyrolysis and gasification‐based business models different from the waste to energy concept. Negative emissions, energy storage, stabilization of renewable grids as well as renewable fuels must be mentioned as examples of such new products. Thus, thermochemical processing technologies should be embedded into the wider concept of circular, low carbon economy as the source of energy for recycling, a technology of tertiary recycling of synthetic polymers and as a way to transform nonrecyclable rejects into fuels, negative emissions, and other marketable products. This article is categorized under: Bioenergy > Systems and Infrastructure

“…The Shrinking Core Model (SCM, Equation 3) consists of a reaction that first occurs on the outer surface of the particle and then continues progressively inside the particle (Jeong et al, 2014). For this model, the particle porosity remains constant and the particle size decreases with the conversion kinetics of the char (Yang and Chen, 2015).…”

“…Research shows that the mineral composition of the char has a strong impact on the processing, application and environmental, technological concerns associated with these fuels (Zhang et al, 2008;Skodras et al, 2015;Qian et al, 2015;Yang and Chen, 2015). For biomass, the variability in the mineral content of plants can be considerable, as it depends on genetic and environmental factors or origins, it also depends on physico-biological differences between crops (Xie et al, 2012).…”

This study presents the gasification of three types of biomass residues (wood, stem and shells) under CO 2 and water steam, using the different analyses X-ray fluorescence (XRF). Generally, the experiments are carried out using XRF installations and a fixed bed reactor system. The tests are carried out on wood, stems, and shells, because of their energy contents (Lower heating value LHV), and their high availability in the Ziguinchor region (Senegal). The solid residues obtained after pyrolysis were used to carry out the gasification tests. Thus, several gasification tests were carried out and the results were interpreted using the Arrhenius equation. Two kinetic models (Volume Reaction Model, and Shrinking Core Model) were used to explain the influence of experimental parameters (nature of biomass, reagent type, and temperature) on synthesis gas production. From the experimental results, it is found that the nature of the sample, the reagent, and the variation in temperature have significant effect on the char kinetics conversion. In addition to the differences in the chemical composition of the raw sample, ash and char density, an explanation on the parameters effects, which vary the conversion kinetics during the gasification tests is given. The purpose of this work is to understand the kinetic variations of raw materials in the fixed bed reactor during gasification.

“…La energía de los lodos orgánicos se puede aprovechar utilizando tratamientos térmicos, como pirólisis y termoquímicos, como la gasificación. Durante el proceso de gasificación se pueden obtener productos como syngas, bio-oil y biocarbón, en presencia de un agente oxidante y a levadas temperaturas [3], [1].…”

“…Las áreas más afectadas se ubican en Cerro Punta, Comarca Ngöbe Buglé, Sabana Central Veragüense y el Arco Seco [10]. El aprovechamiento de la biomasa residual permite disminuir la acumulación de residuos, debido a revalorización de la materia prima [1], [3]. En Panamá, aproximadamente, se vierten 70 Ton/día de lodos orgánicos al relleno sanitario Cerro Patacón, proveniente de la PTAR de la Ciudad de Panamá [10], [11].…”

En Panamá, los lodos orgánicos de las plantas de tratamiento de aguas residuales (PTAR) no se utilizan en su totalidad. La carbonización de estos lodos se presenta como una alternativa para la gestión de este residuo orgánico. La carbonización de la biomasa produce un material rico en carbono conocido como biocarbón. Además del contenido de carbono, este material contiene nutrientes que podrían mejorar las propiedades fisicoquímicas del suelo y proporcionar porosidad que mejoraría la retención de agua y nutrientes. En Panamá, el 27% de los suelos están degradados debido a prácticas irregulares de aplicación de fertilizantes y pesticidas. Las áreas más críticas de degradación del suelo son Cerro Punta, Comarca Ngöbe Buglé, la Sabana Central Veragüense y el Arco Seco. El objetivo de este proyecto fue evaluar la producción de biocarbón utilizando mezclas de cáscara de arroz y biosólidos de una PTAR. Se utilizaron mezclas de 85%, 75%, 65% y 55% de lodos orgánicos, y el porcentaje restante representó la cantidad de cascarilla de arroz para cada mezcla. Los resultados mostraron la necesidad de agregar materia volátil a la mezcla para el correcto funcionamiento del reactor. La mezcla de 75% de lodo orgánico y 25% de cáscara de arroz produjo biocarbón con el mayor potencial para mejorar las propiedades fisicoquímicas del suelo. Presentó un pH de 12,25 y una productividad de 35,48%. El uso de materia orgánica procedente de residuos carbonizados se proyecta como una alternativa para mejorar los suelos degradados y promover una economía circular y un desarrollo sostenible.
