Correction for ‘A review on thermochemical based biorefinery catalyst development progress’ by Mortaza Gholizadeh et al. , Sustainable Energy Fuels , 2023, 7 , 4758–4804, https://doi.org/10.1039/D3SE00496A.
Herein, it is aimed to investigate the effect of zeolite catalyst on the co‐pyrolysis process of waste tyre and poplar wood. A laboratory‐sized reactor is used to pyrolyze 15 g of sample at 500 °C under atmospheric pressure. In the results, it is indicated that co‐pyrolysis affects the properties of the products. Comparing to single feedstock, the co‐pyrolysis enhances the yields of bio‐oil, while reducing the formation of char. The pyrolysis of poplar wood produces 23.3 wt% of bio‐oil, while the pyrolysis of tyre yields 25 wt% of bio‐oil. However, it is 31.29 wt% for the co‐pyrolysis process. Higher content of valuable compounds are formed in the bio‐oil, which improve the fuel properties of the bio‐oil. The zeolite catalyst alters the characteristics of the products obtained from the co‐pyrolysis process. The gaseous products show a decrease in the concentrations of carbon monoxide and carbon dioxide when the catalyst is present. The liquid product analysis reveals the presence of light aromatics such as ethyl benzene and light linear compounds such as alkanes including octane, hexane, etc. The analysis of the catalysts suggests that a very small amount of coke deposits on the catalyst due to the slight increase in carbon content.
Abstract The design and implementation of membrane bioreactor (MBR) pilot plant was performed in order to treat municipal wastewater derived from the Súria municipality (Catalonia, Spain) wastewater treatment plant. Two submerged membrane configurations (flat sheet and hollow fibre) in MBR pilot plant were used for this purpose. The influent and effluents were monitored and controlled in order to ensure the achievements of the highest quality determined by Spanish legislation for water reuse. The Remosa company interest was focused in pilot plants applications for the small urban areas. Taking into account that the level of control and maintenance of this small plant can be lower than recommended, the start-up was performed under less favourable conditions without any sludge seed. After 8-months of continuous operation, the physico-chemical and microbial parameters of both MBR configurations achieved the water quality specifications defined for urban service, agricultural and recreational uses. The flat sheet configuration reported easier operation and maintenance (chemical cleaning frequency) compared to the hollow fibre one.
