“…The conversion process of carbon-based solid materials into gaseous fuels at high temperatures, generally from 800 to 900 °C, to optimize gas production, is gasification. 29,148 For de Caprariis et al, 29 gasification is one of the most promising technologies to convert low-quality fuels into more valuable ones (Fig. 6).…”

“…The plant design presented in this study allowed for minimizing the heat dispersion, enhancing the unit energy efficiency. 29 Sikarwar et al 154 reviewed biomass gasification for biofuel production, and demonstrated that this is an attractive option. The authors presented recent progress in gasification techniques and key generation pathways for biofuels production, such as process design and integration and socioenvironmental impacts of biofuel generation, investigating gasification-to-biofuels credentials as a sustainable and eco-friendly technology.…”

“…19 Many studies showed that biomasses from oilseed fruit and its wastes can be used for biofuel and bioenergy production by different thermochemical processes -for instance, direct combustion, pyrolysis, oxy-fuel combustion, gasification, and transesterification. 7,[19][20][21][22][23][24][25][26][27][28][29][30] These thermal conversion methods vary depending on the oilseed fruits used as feedstock for biofuel production. The characteristics of the biofuels produced also vary depending on the feedstock and method used.…”

The characterization of the physical-chemical properties and the thermal behavior of oilseed fruits for biofuels production has gained interest in the scientific community and society more generally, in particular with regard to their use as partial replacements for fossil fuels and for the possible reduction of air pollutants that cause problems for human health, animals, and plants. These oilseed fruits, which are rich in lipids, triglycerides, fatty acids, carotenoids, and other greasy compounds, can be transformed into solid, liquid, and gaseous products by different thermochemical conversion processes (conventional combustion, pyrolysis, oxy-fuel combustion, gasification and transesterification). This review investigates the different oleaginous feedstocks commonly found in the forests and plantations of Brazil -for example, olive stones, palm fruits, babassu coconut, macauba fruits, tucumã seeds and soybeans, and the respective residues generated from biofuel production and manufacturing processes. The main opportunities and challenges associated with the use of biofuels produced from these oilseed fruits lie in the fact that internal combustion engines using fossil fuels do not need to undergo modifications and mechanical adaptations to operate, and there is no corrosion risk and / or deterioration of metallic parts. Biofuels produce less greenhouse gas, or their pollution is considered neutral. Finally, the native forests of Brazil and the world present a vast number of different oleaginous species that still need be studied because they have excellent potential to be used as biofuels, as they are renewable energy sources and are sustainably eco-friendly.

“…The reforming reactor is equipped with a cable heater to minimize the heat loss from the reactor walls and to sustain the endothermic reactions, and with a steel net to support the catalyst bed. The catalyst used for the experimental tests is a CeO 2 promoted bimetallic Ni-Co catalyst supported on γ-Al 2 O 3 [60]. The plant details are provided in [61].…”

Modeling and Experimental Study of a Small Scale Olive Pomace Gasifier for Cogeneration: Energy and Profitability Analysis

A thermodynamic model of a combined heat and power (CHP) plant, fed by syngas produced by dry olive pomace gasification is here presented. An experimental study is carried out to inform the proposed model. The plant is designed to produce electric power (200 kW el ) and hot-water by using a cogenerative micro gas turbine (micro GT). Before being released, exhausts are used to dry the biomass from 50% to 17% wb. The ChemCad software is used to model the gasification process, and input data to inform the model are taken from experimental tests. The micro GT and cogeneration sections are modeled assuming data from existing commercial plants. The paper analyzes the whole conversion process from wet biomass to heat and power production, reporting energy balances and costs analysis. The investment profitability is assessed in light of the Italian regulations, which include feed-in-tariffs for biomass based electricity generation.

“…In this study, the focus is on the catalytic methane cracking in a char fixed bed. Methane is the second most concentrated byproduct in the output gas of a gasifier 21 (after CO 2 ). Its cracking can significantly improve the yield of biomass conversion into syngas and it represents a possibility to adjust the H 2 /CO ratio since the reaction produces additional hydrogen (see eq 1).…”

Syngas production enhancement via catalytic methane cracking onto metal-loaded chars, with a specific focus on the activity of two inherent alkali and alkaline earth metals (AAEMs), Ca and K, was investigated. Chars produced from the gasification of poplar wood pellets were heated to 700°C in an inert atmosphere and then tested as catalysts for methane cracking at 700°C. Methane is one of the most abundant biomass gasification byproducts. The cracking of this component is relevant in increasing the syngas production and yield. The syngas production was increased by a factor 1.9−2.7 using metal-loaded chars. Results were explained by the catalytic effect of AAEMs on both the desorption of oxygenated functional groups and on the catalytic methane cracking. AAEMs promoted methane molecule combination with the active sites such as oxygenated groups available at the surface of the chars enhancing both H 2 and CO production. It was observed that potassium-loaded char (K-char) showed the best performance. The calcium-loaded char (Ca-char) was less efficient, due to a higher amount of silicon that interacted with calcium to form silicates. No synergetic effect was observed on the syngas production with the Ca+K-char.
