The 2-phosphinophosphinine 2-PPh2-3-Me-6-SiMe3-PC5H2 (2) has been prepared and was shown to act as a κ2-chelating ligand in cis-[RuCl2(2)2] (4). Complex 4 was a competent precatalyst for the room temperature transfer hydrogenation of acetophenone (0.1 mol% 4 and 0.5 mol% KOtBu) and the conversion of methanol/ethanol mixtures to the advanced biofuel isobutanol in 50% yield and 96% selectivity.

Coproduction of biofuels with biochar (the carbon-rich solid formed during biomass pyrolysis) can provide carbon-negative bioenergy if the biochar is sequestered in soil, where it can improve fertility and thus simultaneously address issues of food security, soil degradation, energy production, and climate change. However, increasing biochar production entails a reduction in bioenergy obtainabl...

Energy-intensive chemical conversion of crude algal oils into biodiesel is a major barrier for cost-effective algal biofuel production. To overcome this problem, we developed an enzyme-based platform for conversion of crude algal oils into fatty acid methyl esters. Crude algal oils were extracted from the oleaginous microalga Nannochloropsis oceanica IMET1 and converted by an immobilized lipase...

Methanol is considered to be a viable option for reducing greenhouse gas (GHG) emissions in shipping, the second-highest emitter after road freight. However, use of fossil methanol insufficient meet climate change targets, while renewable yet unavailable on commercial scale. This paper presents novel biorefinery concept based biomass solvolysis produce crude lignin oil (CLO) from forest residue...

Significant amounts of ethanol are produced from biofuel crops such as corn and, in the future, likely switchgrass. The atmospheric effects of growing these plant species on a large scale are investigated here by measuring the plant-atmosphere exchange of volatile organic compounds (VOCs). Field grown corn and switchgrass emit VOCs at flux rates of 4.4 nmolC m 2 s 1 (10 9 mol carbon per square ...

Endophytic fungi, isolated from a number of different species of tropical plants, were investigated for lipid biodiesel precursor production. The extracts produced from liquid cultures of these fungi were subjected to acidcatalyzed transesterification reactions with methanol producing methyl esters and then analyzed through chromatographic (GC-FID) and spectrometric techniques (MS, NMR ¹H). The...

Biofuel, a form of renewable fuel, has promising future, especially as the alternative fuel for transportation. Biofuel is usually blended with petroleum fuel and used in flex fuel engines. Since the characteristics of biofuel are quite different from those of the petroleum based fuel, it is very important to optimize the combustion properties for biofuel engines under different fuel blends. Th...

P hotosynthesis is the model process for storing solar energy in complex chemical bonds. Annually it results in the fixation of upwards of 120 billion tons of carbon through terrestrial plants alone1, and nearly as much again inside the world’s oceans2. Humankind has sought over decades to mimic this process synthetically; however, to date, photosynthesis remains the only option for the sustain...

The ambitious CO2 emission reduction targets for the transport sector set in Paris Climate Agreement require low-carbon energy solutions that can be commissioned rapidly. production of gasoline, kerosene, and diesel from renewable methanol using methanol-to-olefins (MTO) Mobil’s Olefins to Gasoline Distillate (MOGD) syntheses was investigated this study via process simulation economic analysis....

A biofuel cell is a device for converting chemical energy to electrical energy by a simple way. A high-impact anode is prepared in this research. Here, carboxylated multiwall carbon nanotube (COOH-MWCNT), polydiallyldimethyl ammonium chloride (PDDA) and alcohol dehydrogenase were cast on modified glassy carbon with polymethylene green to construct the bioanode for ...
