Biodiesel and other technologies: "New Process" of Biodiesel production
"New process"
According to our inventive process the advantages of alkaline transesterification of triglycerides and esterification and transesterification of triglycerides with homogenous catalyst were joined together. This is reached by carrying out conversion of oils into one or maybe two steps. (See enclosed scheme.)

- Very short reaction
time, 30 min - >95% reaction
- No salt
- No soap
- Waste is 99% water
- No stirring
- Simple distilling of glycerol
- High temperature
- High pressure
- Distilling of methyl esters fatty acid
if only one step reaction is used

Roundup: The “biodiesel miracle,” bargain-priced “green” gasoline and a sweet new biofuel source
Jeremy Jacquot | April 26th, 2008 | 3 Comments
Here are a few of the latest startups we’ve spotted promising cheaper, easier ways to turn organic material into fuel:
Minnesota undergraduates use “Mcgyan Process” to produce cheap biodiesel — Ever Cat Fuels claims its proprietary technology, dubbed the “Mcgyan Process” (after the names of the inventors McNeff, Gyberg and Yan), can convert most feedstocks into biodiesel without producing too must waste or consuming much water — a technology loftily deemed “one of modern day’s great discoveries” by Augsburg President Paul Pribbenow. A highly efficient metal oxide catalyst accelerates the continuous, or “flow,” process, in a fixed bed (tubelike) reactor.
Unlike conventional biodiesel production, which can take several hours to complete and often produces waste, the Mcgyan Process only takes a few seconds to complete. Ever Cat Fuels is building a $5 million plant in Isanti, Minnesota, that could eventually generate over 3 million gallons of biodiesel each year. The ambitious start-up is eyeing algae as its first potential source of feedstock oils.
UMass researchers develop cheaper, “green” gasoline — No, that’s not a typo: A team of researchers at UMass, Amherst, led by chemical engineer George Huber, has developed a new process to refine hydrocarbons from cellulose. This “green” petroleum can be produced from a variety of biomass sources, including feed stocks, wood scraps and corn husks, and, because it’s made of hydrocarbons, can be pumped directly into existing car engines. To produce this gasoline variant, Huber heats cellulose in the presence of solid catalysts and rapidly cools the products — leaving behind a liquid containing most of the compounds found in gasoline, such as toluene and naphthalene. It needs only a moderate amount of heat and takes less than 2 minutes to complete. Once the process hits a 100% yield — it’s at 50% now — Huber estimates that it coul -

Permeability of CO2 through chitosan membrane swollen by water vapor in feed gas
UMMARY:
The permeation and separation of carbon dioxide through a water-swollen chitosan membrane was studied. A chitosan membrane exhibited a large gas permeability when it was swollen by water vapor contained in the feed gas. Carbon dioxide preferentially permeated through the swollen chitosan membrane with a permeability of 2.5×10-8cm3(STP)･cm/(s･cm2･cmHg) and a CO2/N2 separation factor of 70 at room temperature. This separation performance for CO2 resulted from a basic property of the amino groups in the chitosan molecules. The membrane preparation method such as acetic acid concentration of the casting solution affected the membrane permeation rate. The effect of operation temperature was also measured. To increase the separation performance of the membrane, several methods of membrane treatment and operation were evaluated. -

Biomass (living organism bio-waste) is the only renewable energy source that causes danger to the environment if it is not utilised.
* Global waste biomass energy capacity is about eight times the total annual world consumption of energy from all sources. Therefore, biomass represents a very large energy resource.
* At present the world population uses only about 7% of the annual production of biomass. Therefore, we are only partially exploiting nature's abundant renewable resource.
* Fossil fuels are nonrenewable-finite sources. Renewables will never run out. -
