Summary: This study demonstrates the catalytic conversion of renewable plant oils, including microalgae and waste oil, into industrially relevant alpha-olefins in the C-3 to C-10 regime. The biorefinery concept involves a catalytic sequence of ethenolysis, double bond isomerization, and subsequent ethenolysis, effectively rearranging the fatty acid chains into valuable chemical building blocks. Supercritical carbon dioxide (scCO(2)), a benign extraction and reaction solvent, is utilized.

Summary: In this review, the conversion of biomass-derived carbohydrates, such as glucose, into value-added chemicals through heterogeneous catalytic and electrocatalytic pathways is discussed. The focus is on the conversion of glucose into sorbitol, gluconic acid, and glucaric acid, with emphasis on catalyst type, conversion efficiency, target-product selectivity, and performance. Various catalysts and electrocatalysts for the hydrogenation and oxidation of glucose are evaluated and compared. This systematic review is expected to provide meaningful guidelines for the development of highly efficient catalytic platforms for the conversion of glucose into value-added chemicals based on hydrogenation and/or oxidation.

Summary: The study focused on transforming residual fatty raw materials into third generation green diesel using an active nickel catalyst supported on mineral palygorskite. Biodiesel can be converted into green diesel faster than RFRMs. The composition of the total green diesel is highest in CHO and lowest in SCGO. The catalyst does not affect its main physicochemical characteristics.

Summary: The role of energy transition amidst the energy crisis and how policymakers can drive down emissions while focusing on energy security are critical. The green transition is influenced by factors such as geo-political situation, energy crisis volatility, energy shortage, and climate change. Governments face the challenge of balancing energy security, sustainability, and affordability. Although renewable energy infrastructure is not yet ready to replace hydrocarbon, attention should be given to investments and implementation of renewable energy sources. This paper analyzes the energy crisis of green transition and proposes a framework for inclusive investigations to enable policymakers to drive the green transition effectively.

Summary: Lignin is a major obstacle to biomass conversion, with alkaline extraction being the most commonly used method. However, this technology is environmentally unfriendly and generates difficult-to-handle effluents. Alternative methods, such as using water, biobased solvents, ionic liquids, and deep eutectic solvents under sub- or supercritical conditions, may provide a sustainable approach to lignin removal and biorefinery development.

Summary: Many long-term sustainable energy transition policy decisions rely on models that do not consider environmental impacts and constraints, leading to incomplete and potentially misleading information. The ENBIOS framework integrates a broader range of indicators into energy modelling and policymaking practices, providing deeper insights into potential energy systems.

Summary: Experiments and simulations were conducted to study the air volume fraction and hold-up in a bubble channel reactor. A new signal processing method was proposed to avoid the loss of bubble residence time. The results were in agreement with previous studies and a bubble-scale model was developed to explain the relationship between hold-up and air superficial velocity.
