(NOTE: This post hastily typed with little proof reading.)Today is day two of the
BBI Westcoast Conference.
The conference was kicked off last night with a reception and being the large supporters of the ethanol and
biodiesel this industry is of course the bar flowed with hosted liquor and plenty of free fried food.
Preceding the conference was a
Northwest Biofuels Association (NWBA) meeting which was also noteworthy. Primarily because the subject of "renewable diesel" was floated and discussed.
Provided was a document covering a general overview of "renewable diesel" types (which I will hopefully track down on line and post here).
If you are unfamiliar with "renewable diesel" there are several processes being pushed forward with one being an 800 lbs gorilla to the
biofuels industry.
The first type (the most exciting) is commonly called
thermal depolymerization which essentially forces on a commercial scale version of the geological processes that turn carbon rich materials such as agricultural waste into a crude oil which can be refined similar to petroleum.
Another exciting technologies (perpetually five more years from mainstream commercialization) along the same lines is
Fischer-Tropsch. Similar to thermal
depolymerization except from what I understand this process enables a commercial plant to go directly into a motor fuel during the processing of the
ag-waste, coal, etc.....
Another is a process being pursued aggressively by a local Oregon company
WEVCO Biodiesel. Tim
Wetzel and Craig Porter the owners of this company are acquaintances and industry friends of mine so I'm very familiar with their promising technology.
The way it works (in great contrast to
COP's version) is that large volumes of renewable oils (yellow grease, tallow, canola oil, soy oil, palm oil, etc...) is mixed with a petroleum component (diesel, jet fuel,
distilate,
transmix products, etc..) and is then catalyzed together. So some high blend (over 50% from what I understand) of vegetable oil is mixed with petroleum and then catalyzed into a fuel that meets
ASTM D975 specification for
onroad and
offroad diesel. This process does not throw off
glycerine and therefore has a higher yield of product and no lower value waste stream.
Now for the 800 lbs
gorilla.
Conoco Phillips (COP) and other major oil refiners have come up with a "renewable diesel" concept of their own. When I first heard of this process and saw a presentation about it from COP I immediately thought it was one of those wacky World War II ideas that had been
shelved with the consistent low prices of petroleum since the era of war time rationing. I could literally imagine some old-timer form the
Conoco or Phillips 66 lineage sending an old moldy copy of some paper from the 1950's to the cutting edge researchers of today.
This technology (from my passing understanding) takes natural oils (the vegetable and animal fats) and mixes it with the distillate product at the
refinery before it goes into the
hydrocracker. These mixing ratios being around 2% (just in line wit
RFS biodiesel blending requirements). This process then turning the vegetable/animal oil into many other petroleum products and being accounted for as a
biodiesel product by accounting. COP considers this a displacement of petroleum and wants this to be considered a renewable extender of diesel.
What makes this the 800 lbs
gorilla? The fact that most of the
feedstocks used by the
biodiesel industry are less expensive for a major oil refiner to buy than crude petroleum and therefore big oil could suck up all the feedstock freezing out the fledgling
biodiesel industry. Worth also mentioning the US IRS has recently even extended the $1/ gallon
biodiesel tax credit for this process.
If you can imagine this led to a serious group of discussion primarily outside of the
NWBA meeting. Regardless its always interesting to be in a room full of cutting edge technical people when they start arguing about technology.
This just makes me look that much more forward to the
NBB Conference in February. Nothing like outside the box thinkers to get you working harder.
