“…In order to analyze the CH4 yield, a simulation model of the plant has been constructed and implemented in Aspen Plus [21]. The plant lay-out, covered by patent [23], is reported in Figure 8 and is composed by a water shift reactor for the transformation of CO into CO2, and by four Sabatier catalytic reactors where the following reaction takes place: CO2 + 4 H2 → CH4 + 2 H2O A CO2 capture system using KOH solution and a water separator assure the production of a high pure methane stream.…”

“…An initial experimental campaign has been conducted utilizing a small-scale downdraft gasifier (roughly 100 kWth). The results have been utilized to set a pseudo-kinetic model of the gasification process, implemented in Aspen Plus environment, already developed [20,21]. The model has then been used to analyse the performance of the oxy-CO2 gasification strategy varying the operative parameters.…”

“…To achieve this goal, research are focused on achieving effective syngas clean-up and purification and the development of new catalysts [25][26][27][28][29]. Gasification technology is being used to produce a variety of chemicals such as methane, methanol, ammonia, hydrogen, and sustainable aviation fuels [30][31][32][33][34][35][36], which can help reduce the reliance on fossil fuels for chemical production. This approach, coupled with CCS technology to capture and store carbon emissions, has the potential to significantly reduce greenhouse gas emissions from the chemical and energy sector [16].…”

“…Biomass has been thermochemically converted into different products, such as oil, char, and chemicals as well as syngas [ 7 , 8 , 9 , 10 , 11 , 12 ]. Among various thermochemical technology, gasification is considered as the most promising approach because the produced gas can be used in many fields [ 13 , 14 , 15 , 16 , 17 ].…”
