“…It is an effective technology for producing hydrogen to be used in fuel cells and internal combustion engines. Biomass has the potential to become a significant source of renewable hydrogen [12,13]. During gasification biomass feedstock turns into syngas gas mixture by the partial oxidation reactions taking place at high temperatures (800-1000 °C) [14].…”

Gasification is a promising clean energy technology for hydrogen production and sustainable waste management. Biomass residues have great potential to produce renewable hydrogen. In this study, the potential of production of hydrogen from pepper residues was determined via a modeling study of air/steam gasification system. The input carbon of the feedstock was assumed to be fully gasified in the numerical model calculations performed for the downdraft gasifier system. Air to fuel ratio (A/F) and steam to fuel (S/F) ratio are taken as 0.05 because of the high oxygen content in pepper waste. The temperature of the gasifier is 877 °C for the developed mathematical model. The modeling study results revealed high hydrogen content in the producer gas derived from pepper waste gasification which has obtained as 49.08 %.

“…The pore formation of biochar is 90 closely related to the release of volatiles from polymeric backbone of carbonaceous feedstock 91 (Chen et al, 2015). High volatile matter contents in the feedstock could promote the 92 development of porous structures and the reactivity of biochar (Pacioni et al, 2016). Total pore 93 volume is critical for the solid-gas interaction and exchange between gaseous reactants and the 94 active sites on the surface of biochar (Sun et al, 2012).…”

20This review lays great emphasis on production and characteristics of biochar through gasification. 21Specifically, the physicochemical properties and yield of biochar through the diverse gasification 22 conditions associated with various types of biomass were extensively evaluated. In addition, 23 potential application scenarios of biochar through gasification were explored and their 24 environmental implications were discussed. To qualitatively evaluate biochar sustainability 25 through the gasification process, all gasification products (i.e., syngas and biochar) were 26 evaluated via life cycle assessment (LCA). A concept of balancing syngas and biochar 27 production for an economically and environmentally feasible gasification system was proposed 28 and relevant challenges and solutions were suggested in this review. 29 30

“…Nevertheless, the heating value diminishes if the ash content of biochar increases [17,18]. Pacioni et al [19] produced biochar from three agro-industry residues in a fixed bed reactor, concluding that biochar has the potential to generate energy through the gasification process mainly due to its high calorific value (>28 MJ/kg). Misinna and Rajabu [20] and Njenga et al [17] obtained biochar derived from cookstoves (top lit updraft natural draft) and evaluated it by feeding back in TLUD cookstoves; the authors concluded that biochar as a fuel for cooking reduces the wood consumption by 40%-50%.…”

In this study, the effects of biomass type and airflow rate on the fuel and soil amendment properties of a solid byproduct (biochar, BC) produced by gasification in a top‐lit updraft reactor are studied. The results indicate that biomass with the highest fuel value index produces BC with the highest quality as a solid fuel. The best properties as a soil amendment are reached by Gua‐30‐BC as follows: the cation‐exchange capacity (CEC) of 18.6 meq/100 g, the water holding capacity (WHC) of 438%, and the total oxidizable organic carbon (TOC) of 14.2%. When the airflow increases from 20 to 40 L/min, the properties of pine BC as a solid fuel are affected. An increase in the gasification temperature leads to a diminished bulk density. Moreover, the ash content increases affecting the heating value of BC, which decreases from 27.71 to 25.5 MJ/kg. The best properties of BC as a solid fuel are reached at 20 L/min. The properties of BC as a soil amendment are affected with increased airflow as follows: the CEC decreases by 22.8%, TOC increases by 232.3%, and WHC increases by 7.6%. The best properties of BC as a soil amendment are obtained at 40 L/min. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13105, 2019
