socalboomer February 6, 2014 06:44 PM Here's hoping it leaves your exhaust smelling like french fries. . . like biodiesel does. :) The Skud February 6, 2014 11:58 PM Couldn't you call any blend of corn-based ethenol and gasoline a "biopetrol"???? Noel K Frothingham February 7, 2014 02:06 AM The Skud, the article describes a product - a 'biopetrol' that would be a direct replacement for gasoline. You refer to a 'blend' of ethanol and gasoline, with the current acceptable recipe calling for 90% gasoline to 10% ethanol. So in my opinion, no. They are two distinctly different formulas/products. Rex Zietsman February 7, 2014 06:31 AM This may sound like a "break through" but in reality, it can be done using existing conventional equipment. This would be a cracker followed by a hydrotreater designed to handle a higher oxygen load than petrochemical oils. The final twist is that there is a layer of isomerising catalyst in the bottom of the hydrotreater to change from polymers from linear to branched. We are doing this in synthetic diesel production from biomass. In our case we do not crack all the way down to gasoline (but could) and then hydrotreat and, in winter, isomerise. Mel Tisdale February 7, 2014 10:06 AM Whenever I hear mention of bio-fuels among the things that spring to mind is a long conversation that I once had with a fuel engineer who worked for a well-known aero engine manufacturer. This happened about six years ago now, so things might have improved in the meantime, but this engineer expressed a concern that her work on bio-fuels had shown that they degraded markedly compared to conventional fuels and storage needed careful monitoring. (Obviously, long-term on-board storage is not a problem with aero engines.)I imagine most diesel engined vehicles also cycle their fuel quite rapidly, especially seeing as most are commercial in nature. On the other hand, gasoline powered vehicles sometimes gather dust for months, only coming out on high days and holidays. I assume such usage will be considered in the event of any changeover to bio-gasoline. It might make little difference or it might be vital. It would be sad for the family, all dressed up in their Sunday best, to get into their 1928 vintage Bentley, which is their pride and joy, to go for a trip to the sea-side, only for it not to start because the fuel had degraded too much over the winter. (Even starting the thing every fortnight or so, wouldn't do anything to help fix the problem, if problem there be, of course.) michael_dowling February 7, 2014 01:29 PM Well,Mel,anybody owning any kind of vehicle that is put in storage for months should know that fuel,even petroleum based fuel,deteriorates over time-ignorance is no excuse. Observer101 February 7, 2014 01:44 PM While this is interesting, I always wonder how much cheaper is it, is it as powerful as current fuels, and what will it cost at the pump? Also, what changes to vehicle fuel delivery systems must be made… it all sounds good, but is it economically viable, and can it be mass-produced? Robert Fallin February 7, 2014 01:58 PM Great; just in time for electric and fuel-cell vehicles. Seriously, this makes the arguments against fracking, drilling and pipeline a LOT more credible. donwine February 7, 2014 02:21 PM Will it become illegal to make our own? Pat Kelley February 7, 2014 02:32 PM Don't hold your breath. When an academic institution makes an announcement like this, you can be guaranteed they're angling for more grant money. I've counted over a thousand such "breakthrough" articles over the last decade, and have yet to see any of them result in a real product. How many decades have we pursued the elusive fusion power, and how many hundreds of billion dollars spent without reaching breakthrough?This is not to say that energy technology won't continue to improve, but the evolutionary path to combustion-free power is going to take time.
