Summary: This paper proposes a two-stage process combining biomass pyrolysis and CO2 catalytic reforming to prepare high-calorific value syngas rich in H2 and CO, while reducing the by-product tar of biomass gasification. The effects of reforming temperature and CO2/C ratio on the gas yield and calorific value of biomass were investigated, and the system energy consumption was analyzed. Under the conditions of a reforming temperature of 900°C and a CO2/C ratio of 1, high-calorific value syngas with a value of 2.75 MJ/kg, and maximum yields of H2 and CO of 0.46 Nm(3)/kg and 0.28 Nm(3)/kg were obtained. The total energy consumption of the system was 0.68 MJ/kg, slightly higher than 0, and without the need for excessive external heat.

Summary: Biomass gasification produces syngas containing various components such as hydrogen, carbon monoxide, carbon dioxide, methane, water, and higher hydrocarbons like ethane. A study on the steam reforming process of five different streams, obtained from three biomass sources, was conducted using Aspen Plus V12 software and Gibbs energy minimization method. Various operating conditions were assessed, and it was found that temperature, pressure, and steam-to-carbon ratio significantly influenced the hydrogen content in the streams. The hydrogen purity and yield were highest for the stream obtained from the gasification of Lignin followed by conditioning, while coke formation could be mitigated by specific conditions.

Summary: This study demonstrates power generation using solid oxide fuel cells fueled with biosyngas from microwave-enhanced pyrolysis of algae. The power density of the cell fueled with laminaria biosyngas is 379.8 mW/cm2 at 0.8V, which is approximately 91.7% of the density of a cell fueled with pure hydrogen. By adding 5% water to the laminaria biosyngas, carbon deposition can be inhibited and the cell can operate continuously for 800 hours at 750°C. The study also analyzes temperature fluctuations within the cell under different current densities through simulation, providing practical efforts to improve solid oxide fuel cells for biosyngas consumption.

Summary: A novel pyrolysis followed by in-line cascaded catalytic reforming process was developed to produce high-purity syngas from woody biomass without additional steam. This process utilizes biochar and NiAl2O4 catalysts to promote cracking of large oxygenates and reforming of small molecules, resulting in high syngas yield and gas energy conversion efficiency. The sequential promotion in separated catalyst layers maximizes syngas production and improves the activity and stability of the Ni-based catalyst.

Summary: The co-hydrothermal liquefaction of Prot lignin and Sargassum tenerrimum macroalgae in different solvents and feedstock blending ratios was investigated. The results showed that the bio-oil yields were lower and solid yields were higher in co-liquefaction experiments compared to individual lignin feedstock, while the opposite trend was observed for macroalgae feedstock. Gas chromatography-mass spectrometry analysis revealed the composition of bio-oils, and Fourier transform infrared spectroscopy and elemental methods were used to analyze the bio-chars. This study demonstrated an efficient co-HTL process and provided insights into compound distribution and carbon functionality in the products.

Summary: The increasing demand for sustainable energy and chemicals, along with the declining fossil fuel reserves, has led to the search for alternative feedstocks and processes. Short-chain olefins are important for the polyolefin industry and require an alternative process to meet future demands. This study demonstrates that single-cell oil (SCO) derived from the oleaginous yeast Rhodotorula mucilaginosa IIPL32 could be used as a renewable feedstock for olefin production. A PtSn/alumina catalyst showed high selectivity to C2-C4 olefins, which can be attributed to the selective catalytic cracking of long-chain lipid molecules over nanosized PtSn/alumina and the synergy between surface acidic sites and reducible Pt species.

Summary: Two different zeolites, HY and HZSM-5, with different Si/Al ratios, were used to investigate the effect of zeolite structure on aromatic hydrocarbons (AHs) production during flash hydropyrolysis of cotton stalks. Both zeolites enhanced AHs production, but the pore structure and pore size of HZSM-5 had a more pronounced effect on the reduction of oxygenated compounds. Ni/zeolite catalysts were also studied, and they promoted the conversion of phenolics and other oxygenated compounds, resulting in increased production of aromatic and aliphatic hydrocarbons through direct deoxygenation, decarbonylation, and decarboxylation reactions.

Summary: This study investigates the use of post Reverse Osmosis (RO)-carbon as an adsorbent for dye removal from water. The thermally activated post RO-carbon (RO900) exhibited a high surface area of 753 m2/g. In batch system experiments, efficient removal of Methylene Blue (MB) and Methyl Orange (MO) dyes was achieved using 0.08 g and 0.13 g/50 mL adsorbent dosage, respectively. The optimized equilibration time for both dyes was 420 min. The maximum adsorption capacities of RO900 for MB and MO dyes were 223.29 and 158.14 mg/g, respectively. The study also demonstrates the successful treatment of simulated effluent with over 99% dye removal efficiency. The use of discarded RO-carbon offers cost and low toxicity benefits, highlighting the significance of this study.
