“…They found that the use of saturated steam increased the concentration of H2 despite its low temperature, due to the beneficial presence of O2. Air-steam gasification of citrus peel residues from citrus juice manufacturing was also studied in a fluidized bed reactor for hydrogen rich syngas production by Prestipino et al [26]. The highest hydrogen yield was found at 750 °C, while the cold gas efficiency reached the maximum value at 850 °C due to the higher concentration of carbon monoxide.…”

The present study investigates the air-steam gasification of ten commercial and alternative lignocellulosic biomass fuels (pine sawdust, chestnut sawdust, torrefied pine sawdust, torrefied chestnut sawdust, almond shells, cocoa shells, grape pomace, olive stones, pine kernel shells and pine cone leafs) in order to evaluate the product gas composition and the process performance in a bubbling fluidized bed gasifier with focus on the different biomass properties. Accordingly, an effort to correlate the biomass characteristics with the gasification results has been done. Pine kernel shell (PKS) was used to test the effect of the gasification temperature (700, 800 and 900 ºC), steam to air ratio in the gasifying agent (S/A=10/90, 25/75, 50/50 and 70/30) and stoichiometric ratio (SR=0.13 and 0.25) on the product gas composition, combustible gas (H2+CO+CH4) production, H2/CO ratio, heating value, energy yield and cold gas efficiency of the obtained gas. Results showed that higher temperature and S/A ratio favored H2 production and gasification performance. A higher value of SR slightly affected the gas composition, but led to a higher process efficiency as a consequence of a higher biomass conversion into gaseous combustible products. All the biomass samples of different origin and characteristics were then gasified at the best experimental conditions found (900 ºC, S/A=70/30, SR=0.25). Gasification of all the biomasses was feasible and H2 and combustible gas concentrations of 30-39 vol% and 59-78 vol% (inert gas-free basis), respectively, were obtained for the biomasses studied, with energy yields of 8-18 MJ/kgbiomass. Torrefied biomass showed similar combustible gas production than the corresponding raw biomass under the conditions studied, but it gave slightly higher H2 production and efficiency results.

“…Further environmental and economic advantages can be reached if syngas is produced by residues or wastes [26]. Gasification is a promising option for the biomass treatment since the gaseous product can be directly used as fuel or as an intermediate product for the production of fuels and chemicals.…”

“…Simulated data have been related to experimental data obtained in a previous work [24] using a laboratory-scale BFB plant as the S/B ratio varied in the range 0-1.25 at 850 °C. Results of validation shown in Figure 6 reveal that increasing the S/B ratio leads to a higher hydrogen and carbon dioxide percentage due to the reduction in carbon monoxide content.…”

Bio-hydrogen from residual biomass may involve energy-intensive pre-treatments for drying and size management, as in the case of wet agro-industrial residues. This work assesses the performance of an alternative process layout for bio-hydrogen production from citrus peel gasification, with the aim of cogenerating heat and power along with hydrogen, using minimal external energy sources. The process consists of an air-steam fluidized bed reactor, a hydrogen separation unit, a hydrogen compression unit, and a combined heat and power unit fed by the off-gas of the separation unit. Process simulations were carried out to perform sensitivity analyses to understand the variation in bio-hydrogen production’s thermodynamic and environmental performance when the steam to biomass ratios (S/B) vary from 0 to 1.25 at 850 °C. In addition, energy and exergy efficiencies and the integrated renewability (IR) of bio-hydrogen production are evaluated. As main results, the analysis showed that the highest hydrogen yield is 40.1 kgH2 per mass of dry biomass at S/B = 1.25. Under these conditions, the exergy efficiency of the polygeneration system is 33%, the IR is 0.99, and the carbon footprint is −1.9 kgCO2-eq/kgH2. Negative carbon emissions and high values of the IR are observed due to the substitution of non-renewable resources operated by the cogenerated streams. The proposed system demonstrated for the first time the potential of bio-hydrogen production from citrus peel and the effects of steam flow variation on thermodynamic performance. Furthermore, the authors demonstrated how bio-hydrogen could be produced with minimal external energy input while cogenerating net heat and power by exploiting the off-gas in a cogeneration unit.

Biomass Polygeneration System for the Thermal Conversion of Softwood Waste into Hydrogen and Drop-In Biofuels

In order to keep the +1.5 °C over-temperature, previously predicted with high confidence by IPPC Sixth Assessment, as minimal as feasible, it is more than vital to achieve a low-emission energy system. Polygeneration systems based on thermochemical processes involve biomass conversion in multi-output of bioenergy carriers and chemicals. Due to reduced energy input and input/output diversification, polygeneration energy systems are considered interesting pathways that can increase competitiveness of biomass-derived products. The proposed route of fast pyrolysis, sorption-enhanced biochar gasification and crude bio-oil hydrodeoxygenation to produce drop-in biofuel and hydrogen is examined. Both kinetic and equilibrium approaches were implemented in Aspen Plus to take into account the effect of the major operating parameters on the process performance and then validated against the literature data. Results show how the process integration leads to improved mass conversion yield and increases overall energy efficiency up to 10%-points, reaching the maximum value of 75%. Among the various parameters investigated, pyrolysis temperature influences mainly the products distribution while Steam/Biochar and Sorbent/Biochar affect the energy conversion efficiency.
