Sasol 100% CTL Synthetic Jet Fuel Approved for Use Internationally in Commercial Aviation

Sasol’s synthetic jet fuel is derived from four synthetic streams: Iso-paraffinic kerosene, Heavy naptha kerosene, Light distillate #1 and Naptha #2.

Sasol’s synthetic jet fuel, produced by its proprietary Coal to Liquids (CTL) process, has received approval for full, unblended use in international commercial aviation. Sasol’s fully synthetic jet fuel (FSJF) is the first such fuel to be approved.

For the past nine years, Sasol has supplied a semi-synthetic jet fuel—a mixture of CTL components with petroleum-derived kerosene—to international airlines operating from OR Tambo International Airport in Johannesburg. Based on the success of the alternative fuel blend and following a several-year period of testing and evaluation, international aviation fuel authorities including the UK Ministry of Defence (UK MoD), governing the Defence Standard DEFSTAN 91-91, approved Sasol’s fully synthetic jet fuel as Jet A-1 fuel for commercial use in all types of turbine aircraft.

ASTM International, originally known as the American Society for Testing and Materials, has also been working closely with the UK MoD and is expected to include Sasol CTL synthetic jet fuel in its ASTM D1655 specification following the publication of the UK’s DEFSTAN 91-91. Jet A-1 according to the DEFSTAN 91-91 specification is very similar to Jet A-1 defined by the ASTM D1655 except for a small number of areas where DEFSTAN 91-91 is more stringent.

Aviation industry stakeholders, including airframe, engine and ancillary equipment manufacturers; airlines and aviation authorities such as the International Air Transport Association (IATA); and relevant oil companies have all participated in the approval process.

The fuel is a drop-in replacement for petroleum jet fuel; it is fully fungible and aligned with the current aviation infrastructure through its compatibility with the existing engine requirements and can be used with conventional crude oil-derived jet fuelling systems.

Sasol produces its synthetic jet fuel from four primary synthetic streams from its high-temperature Fischer-Tropsch (HTFT) process:

*

Iso-paraffinic kerosene, with a few percent n-paraffins and no aromatics; *

Heavy naptha kerosene, with about 10% aromatics; *

Light distillate #1, with about 24% aromatics; and *

Naptha #2, with about 39% aromatics.

The full synthetic jet fuel is ultra-low sulfur (< 5 ppm) and with 8-25% aromatics. Engine-out emissions of Sasol’s jet fuel are lower than those from jet fuel derived from crude oil due to its limited sulfur content.

The current approval covers jet fuel produced at Sasol’s Synfuels facility in Secunda, South Africa. Sasol jet fuel products that will also be submitted for sanction include Oryx GTL plant in Qatar, the joint venture GTL plant in Nigeria and the potential CTL ventures in the USA, China and India.

Research is also underway to find an effective process to produce synthetic fuel from biomass to further improve environmental sustainability.

Rest In Peace, old friend, your work is finished.....

If you want ON or OFF the DIESEL ”KnOcK” LIST just FReepmail me.....

This is a fairly HIGH VOLUME ping list on some days.....

[Red Badger]

Coal to Liquids, Fischer-Tropsch KnOcK!!!!...........

[Stirner]

How much does it cost to deliver a gallon to market?

[Red Badger]

That I don’t know, but the South Africans used this process during the Apartheid era and the Nazis used it during WWII, because both had access to lots of coal, but not petroleum. Another plus is the fuel from coal is low sulfur.......

spent a month just down wind from a hugh gasification plant in the TransVaal back in the late 80s,

stink? you bet it did,, but not as much as the fertilizer plant I was working around.. wheewwwiiiieee,,

[truthguy]

This is the solution:
Build many nuclear power plants for electricity.
Switch over the coal and natural gas that were going to production of electricity to GTL AND CTL and this can give us some breathing room on transportation fuels. Give up on ethanol unless cellulosic pans out. Do not use food stuffs for fuel.
If states like California do not want to build Nuclear Plants-TFB. Let them have blackouts and brownouts with their solar collectors and windmills. The rest of us would not like to freeze to death or have no transportation fuels.

I live across the street from a sewage treatment plant! My sense of smell is gone. Built in 1970 with open tanks. The are building a new one about 3 miles away with the latest technology, totally enclosed and no open tanks to smell. Will go online in June of 2009, and abot 90 days later will shut down this one and replace it with a small pumping station. We (all the neighborhood) are trying to get the County Commisars to build a PARK and recreation area where the plant now stands........I just had an operation last week to remove a tumor from my sinus cavity. Will need more surgery later this summer because it was too big for the surgeon to get it all, since some of it was in some delicate places. He referred me to Shands Hospital in Gainesville, University of Florida Medical School. Still waiting to here from them for scheduling. But in the meantime I CAN BREATHE AGAIN THRU MY NOSE FOR THE FIRST TIME IN OVER 2 YEARS!................Thankfully, Praise be to God!, the tumor was benign.....

[norraad]

Good for you, Shands in G'ville is pretty good, I hope they help you back to 100%>.

Sasol is pretty good, too, I'd like to see some of the procedures they have developed used here.

Some many (Thousands & thousands ) capped wells here in the good ol' USA, can produce unlimited energy based on many techniques they've invented.

To me, it's just more proof we're being driven into the ground on porpoise!

You have been reading my post again!

We are in agreement, go here:

Mil -Spec and this effort will do what the toads in Congress can't.

[scottteng]

Heal quick glad to hear benign. May God watch over your surgeons at Shands. Count your blessings on the smells being gone it was not too many years ago that every city in the world smelled as bad or worse than the plant you lived next to all these years between the privies and the horses. We all need to count our blessings and resist the crowd that wants us to go backwards in time.

Your solution just to get 1 nuke plant online and operational is 10 years at best! To get a refinery online, 7-9 years just in the design and buidling. Realistically with EnviorMENTAList both would take 20 or so years with billions of dollars in cost overruns due to complience. We are so screwed, there is no real way out of this! Thanks Bush for your gutless leadership in not forcing an enery policy down the Democraps throats!!

[truthguy]

But do you agree that this is what we SHOULD do?
I know the idiots will try to stop this until we are up against a catastrophe.
And if you were King, what would you do?

The problems are more political than technical and scientific.

[truthguy]

I read your link and like what you said. We both came up with the identical ideas independently. This must mean that there is some logic involved in getting to the solution. It is very frustrating for me to listen to programs where people talk about energy solutions and do not say a thing about Fischer-Tropsch and Nuclear. All this talk about Solar and Windmills is a bunch of Cra*. The solutions are so obvious. What is wrong with our elected officials? Waxman is a major league AH so I do not expect anything from him. But what about the others.

[Bommer]

Its what we should do, I think its now to a point that th EnviorMentalists won’t allow it. I think when starvation hits this country, the 47 contenential states will declare war on California and whip these @ssholes off the face of the earth. Its time that we start fighting the Domestic enemys of freedom that hide behind the Constitution in our own backyard instead of the foreign ones.

Give up on ethanol????????????????

Can we keep a little bit for drinking, please :)
