VALIUM FOR SALE, Almost since he began studying chemical engineering, George Huber, UMass Amherst professor of chemical and biological engineering, has had an ambitious vision: to make all the same fuels and chemicals from biomass that we make today from crude oil.

As he quickly moved beyond first generation feedstocks like corn and focused on lignocellulosic biomass – woods, grasses, order VALIUM no prescription, and inedible stalks of plants – he became a "pyromaniac, Real brand VALIUM online, " specializing in catalytic technologies.

Huber's breathtaking vision for biofuels

In 2008 Science Daily reported about Huber's breakthough "green gasoline," the first direct conversion of plant cellulose into a liquid identical to standard gasoline, VALIUM recreational. In Huber’s patented, My VALIUM experience, single-step, catalytic fast pyrolysis process, biomass was fed into a fluidized-bed reactor, online buying VALIUM, where it thermally decomposed into vapors, Buy VALIUM online no prescription, which then entered the zeolite catalyst – also inside the same reactor – to be immediately converted into the desired chemicals.

In a 2008 paper in the journal ChemSusChem, Huber and his colleagues reported that the entire process was completed in under two minutes, kjøpe VALIUM på nett, köpa VALIUM online, and the liquid could be further treated and used for high octane gasoline. He explains the original process in this video.

In 2009, he co-authored an article for Science called "The Fuel of the Future Is Grassoline," making the new technology accessible to the public, revealing the breadth of his vision:

The US can produce at least 1.3 billion dry tons of cellulosic biomass every year,  all without decreasing the amount of biomass available for our food, animal feed, or exports. This could produce more than 100 billion gallons per year of grassoline, or about half the current annual consumption of gasoline and diesel in the US.

After the "grassoline" article, and by 2010, Huber had been cited over 875 times in the chemical literature; and this number grows with each new refinement, VALIUM FOR SALE. After VALIUM,

New funding helped refine the catalytic technology

Funding poured in to support Huber’s revolutionary method: $2.4 million from the National Science Foundation, $5 million from the DOD for turning wood and corn waste products into liquid transportation fuels, and $500, online buying VALIUM hcl,000 as part of the DOE's Energy Frontiers. VALIUM images, Last year, while refining the original catalytic fast pyrolysis process, his research team developed a new catalyst that boosted the yield for five key “building blocks of the chemical industry” by a remarkable 40 percent over previous catalysts, fast shipping VALIUM. At the time Huber said, VALIUM without a prescription, “We think that today we can be economically competitive with crude oil production" (press release). The news was published in one the world’s leading chemistry journals, the German Chemical Society’s Angewandte Chemie, online VALIUM without a prescription. A short look at Huber in the lab:

A new direction: fuel cells yield exciting results

VALIUM FOR SALE, Now, in a departure from pyrolysis, Huber has developed a continuous process for converting biomass and electricity into renewable liquid transportation fuels, using fuel cells. "It's what we call electrofuel," said Huber. A paper on the work was published in the journal ChemSusChem. VALIUM photos, The technology, he said, creates a "renewable liquid fuel that fits into the existing petroleum infrastructure." Unlike other technologies that use large quantities of expensive hydrogen gas to convert biomass to biofuels, japan, craiglist, ebay, overseas, paypal, the team's process is driven by electricity. Australia, uk, us, usa, "We're storing the electrical energy as chemical energy," said Huber.

"The advantage is, VALIUM schedule, wherever you have cheap biomass and you have electricity, Where can i find VALIUM online, you could use this technology," Huber told Wisconsin JSOline. Electricity would be used during nonpeak hours when the wholesale price of power is less expensive, VALIUM FOR SALE.

Normally fuel cells convert chemical energy into electrical energy, VALIUM used for, but Huber reversed the process, Effects of VALIUM, reconfiguring it to convert the model biomass compound acetone into isopropanol, with a wide variety of pharmaceutical and industrial applications, including as a gasoline additive, VALIUM australia, uk, us, usa.

Since reactions in a proton-exchange-membrane fuel cell require only water, Real brand VALIUM online, electricity, and biomass to reduce biomass molecules into fuel, Huber's team feeds water into the anode side and passes an electric current through the water to generate protons and electrons, VALIUM online cod. The electrons run through a circuit and the protons pass through the proton-exchange membrane to the cathode side, Buy cheap VALIUM no rx, where they generate hydrogen. The hydrogen reacts with the biomass molecule and reduces it to fuel, while oxygen exits the system, buy generic VALIUM. VALIUM FOR SALE, The process yields 50 percent more liquid fuel over ethanol fermentation processes.

The advance paves the way for researchers to convert biomass molecules such as glucose into hexanes, which are significant components of gasoline currently derived by refining crude oil. In this interview he describes his progress to Chemistry Views:

At the production level, the new process also could be modular, says Huber. "This is potentially a scalable technology where you could make these proton-exchange-membrane-type reactors in the field, close to the biomass."

Always looking to the future, Huber concludes: "It's an exciting time to be in the field of chemistry catalysis. With high oil prices and environmental challenges, there's lots of opportunity for advances to develop these new processes."

In the future, will all petrochemicals come from bio-sources?
