Summary: The research shows that 8% Pd/C catalyst with palm kernel oil after deoxygenation can achieve the best yield and fuel selectivity. The blending of 20% volume of palm kernel oil-derived bio-jet fuel with Jet A-1 fuel is considered the most promising ratio, as it has the most favorable low temperature fluidity and good combustion characteristics.

Summary: The conversion of biomass into liquid fuels has attracted global attention for its potential to reduce pollution. This study investigates the production of drop-in biofuels from date palm seed oil using tantalum phosphate (TaPa) as a hydroprocessing catalyst. The results show that the proposed one-step reaction approach using TaPa catalyst under mild experimental conditions yields high amounts of bio-jet fuel and green diesel fractions. The process is sustainable, efficient, and safe, and has great potential for aviation applications.

Summary: Using fossil fuels in engines has led to energy shortages, carbon emissions, and environmental pollution. Methanol is considered a potential alternative fuel, but its use in diesel engines is hindered by poor auto-ignition properties and low heating value. Blending methanol with vegetable oil, particularly palm oil, has been proposed as a solution. Experimental results indicate stable microemulsions can be formed using methanol and palm kernel oil, with tetrahydrofuran as the most effective co-solvent. Palm kernel oil has a higher affinity for methanol compared to palm oil. Conductivity tests confirm the stability of the microemulsion. This study provides valuable insights for preparing carbon-neutral fuels in diesel engines.

Summary: Bifunctional Co-W catalysts were prepared for the catalytic deoxygenation-cracking of tung oil to produce jet fuel fractions. The CoW/SA catalyst showed the highest activity and outperformed the monometallic Co and W catalysts. It was found that excessively high metal dosages led to over cracking, while lower metal dosages effectively controlled over cracking. The resulting TO-jet fuel had excellent physicochemical properties and combustion characteristics.

Summary: The amount of rubber waste is increasing globally, and it remains in the environment for a long period of time. The polymer recycling industry can address this issue by converting rubber waste into fuel. By using thermal liquefaction with methanol as a solvent, fuel oil was synthesized from natural rubber, yielding a higher percentage of fuel oil compared to tire rubber pyrolysis.

Summary: Biomass-to-liquid thermochemical routes, such as fast pyrolysis, are promising methods for converting waste biomass into sustainable hydrocarbon fuels. However, the bio-oil derived from pyrolysis has poor quality and requires extensive upgrading before it can be used as a jet fuel. Catalytic cracking and hydrodeoxygenation are the most promising approaches for upgrading bio-oil to bio-jet fuel. Further research is needed to understand the mechanistic aspects of raw bio-oil upgrading.

Summary: A new catalytic process for synthesizing jet fuel hydrocarbons from bio-ethanol was developed. This process involves the coupling of ethanol molecules and the hydrodeoxygenation of heavy alcohols to obtain high-carbon alcohols, which can be separated into different carbon chain lengths and then converted into jet fuel hydrocarbons with branched carbon skeletons.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
