In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

Safety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Sustainable bio-jet fuel synthesis techniques for the aviation industry

IOP Conference Series: Earth and Environmental Science
Abstract In the near future, the aviation industry is expected to significantly increase the usage of “drop-in” bio-jet fuel as the technologies in biofuel production advances and matures. Given the high rate of growth in the aviation sector, the demand for aerial transportation of passenger and cargo is projected to increase by two-fold

Physical-Chemical Properties of Jet Fuel Blends with Biofuels Derived from Waste

Chemical Engineering Transactions
Jet fuel blends with bio-based compounds are an alternative for reducing carbon emissions. The properties of the bio-jet fuel blends can be changed by varying the ratio of bio-jet fuel to Jet A-1 fuel.

Playing field for bio-jet fuels : Overview, intercomparison and verification

, 2021
Vilka emissioner och vilken klimatpåverkan har dagens flyg? Detta är viktigt att skapa en samsyn kring för att både kunna jämföra effekter från olika bränslen och andra åtgärder samt för att kunna relatera flygets påverkan gentemot t.ex. andra transportslag. Emissioner från flyg inventeras och rapporteras idag på flera olika nivåer.
