Selective Oxidation Strategies for Cost‐Efficient Green Hydrogen Production via Hybrid Water Electrolysis

Carbon Energy, EarlyView.
Hybrid water electrolysis has emerged as a promising alternative to conventional electrolysis for sustainable hydrogen production. The economic potential of replacing water oxidation with organic substrates is assessed. For each substrate, representative electrocatalysts and mechanistic insights are reviewed to identify design principles for optimized ...

Valorisation of lignin – Achievements of the LignoValue project [PDF]

Lignocellulosic biorefinery for production of biofuels, materials and chemicals requires valorization of all fractions including lignin. As a consequence of its poly-aromatic structure, lignin potentially serves as a source for aromatic chemicals.

Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis

Chemistry – A European Journal, EarlyView.
We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...

Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

The Canadian Journal of Chemical Engineering, EarlyView.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...

Mechanical properties and fire retardancy of bidirectional reinforced composite based on biodegradable starch resin and basalt fibres

eXPRESS Polymer Letters, 2008
Environmental problems caused by extensive use of polymeric materials arise mainly due to lack of landfill space and depletion of finite natural resources of fossil raw materials, such as petroleum or natural gas.

The nature and fate of natural resins in the geosphere XIII: a probable pinaceous resin from the early Cretaceous (Barremian), Isle of Wight

Geochemical Transactions, 2008
Terpenoid resin is produced by all families and most genera of the order Coniferales (the conifers), and the distribution of terpenes present in most conifer resins is characteristic of the originating family.
