A thermo-environmental study of hydrogen production from the steam reforming of bioethanol

Environmental implications of biohydrogen based energy production from steam reforming of alcoholic waste

“…In addition to the basic scheme, a comparison was made with some processes published in the scientific literature. The FU was changed to 1 kg of hydrogen produced in the plant with 99.9 vol% purity by steam reforming (Figure 6), in agreement with other reforming studies using other raw materials for hydrogen production (Hajjaji et al, 2016(Hajjaji et al, , 2013Khila et al, 2016;Susmozas et al, 2016Susmozas et al, , 2015Susmozas et al, , 2013, thus allowing the comparison of does not consider the operation of the SOFC Battery, consequently the output stream of the system is led to a purification system: First, the WGS process removes carbon monoxide and produces a small amount of additional hydrogen. Additionally, in a COPROX reactor the remaining CO can be further reduced to CO2 in the presence of oxygen.…”

“…Biofuel reforming, including also carbon fixation produced during the growth of biomass used for biofuel (Susmozas et al, 2015). SBR-H2: Steam reforming of bioethanol, including bioethanol production (Hajjaji et al, 2016). BAR-H2: Autothermal reforming of bioethanol (Khila et al, 2016).…”

“…Currently, global energy production is based on the use of fossil fuels such as coal, oil and natural gas (Rossetti et al, 2015a) and accounts for approximately 65% of global GHG emissions (Uusitalo et al, 2017). Dependence on the use of fossil fuels as an energy resource has caused environmental problems of global impact, such as air pollution in terms of emission of pollutants and particles, as well as the depletion of natural resources, among others (Hajjaji et al, 2016;Reyes et al, 2015), which leads to adverse consequences for society in terms of human health and damage to the ecosystem (Valente et al, 2019). So much so that the 2030 Agenda and the 17 Sustainable Development Goals (SDGs) set by the United Nations includes ensuring access to affordable, reliable and sustainable energy for all.…”

Warm plasma catalytic coreforming of dilute bioethanol and methane for hydrogen production

“…[1,2] So far, H 2 is mainly produced from fossil fuels, thus the renewable feedstock alternatives for H 2 production have attracted much attention. [3,4] Bioethanol is considered a good candidate for hydrogen production because of its relatively high H 2 concentration, renewability, low toxicity, and easy storage. [5,6] However, ethanol concentration in crude bioethanol is very low (about 3-5 mol%) with a large amount of water.…”

Techno-economic analysis of hydrogen production from dehydrogenation and steam reforming of ethanol for carbon dioxide conversion to methanol

“…Figure 2.12 Relative comparison of the GWP impact of the bioethanol steam reforming system and other alternative routes for H 2 production [48] Currently, one of the most challenges for H 2 production was the process with low production cost and environmentally friendly with minimum CO 2 emission. There had extensive research to promoted cost of H 2 and CO 2 emission in Table 2.7.…”
