The project includes six components: Use the categories and tags listed below to access the nearly 30, articles indexed on this website.
With assistance from the CAAFI Certification and Qualification Team, the following drop-in alternative jet fuels went through the D process and are certified for commercial use listed in chronological order of approval.
As the voice of the U. June 12, Read Full Article. August 3, Read Full Article. Climate March April 29 Photos: Dehydration of isobutanol or ethanol followed by oligomerization and hydrogenation to yield a hydrocarbon jet fuel. July 17, Read Full Article. Why Transition to Sustainable Renewable Fuels?
The wax is then cracked and isomerized to produce drop-in liquid fuels essentially identical to the paraffins in petroleum-based jet fuel, but does not include aromatic compounds.
Prospective alternative fuel producers will need d40554 participate in this committee and engage the other committee members in the evaluation and approval process.
Below are suggested steps to facilitate the D fuel approval process of getting your fuel approved for deployment and commercialization. The current ASTM D Evaluation Process for getting a fuel approved for commercial use includes the following three phases also see figure below: The blend percentage for each concept that goes through the D Fast Track would be limited to a nominal amount such as 10 percent and require the blendstock to meet more stringent specification criteria.
Advanced Biofuels USA events calendar; policy and actions; education newsletters.
The Fast Track provision would permit a limited test protocol of only Tier 1 testing based on acceptable hydrocarbon bulk composition and trace material analyses. Your Alert Profile lists the documents that will be monitored. An example is assessment of incidental materials on fuel properties. Recent Tweets Astmm by AdvancedBiofuel.
Nearly 30, articles in our online library! The results of these efforts will be posted here when available.
These may be discussed and voted on at the semiannual ASTM meeting. ASTM allows a period for comments and review. The approval process is detailed below. This abbreviated testing would result in a new D Annex for each new production concept, but is intended to avoid the need to conduct costly Tier 2, 3, and 4 testing, provided there are certain disclosures of process and management of change by producers. The OEMs are solely responsible for approval of a fuel or additive in their respective engines and airframes.

Mark Rumizen Contact us: There are several efforts underway to develop a more streamlined qualification process to increase process efficiency and decrease the amount of time and capital required to achieve certification. Please first verify your email before subscribing to alerts. Support of Phase 2 Tier 3 and 4 testing and final research report reviews will be contingent on the identification of other sources of funding or in-kind support.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. In the context of Practice Dincidental materials shall be considered as an additive. Please refer to asfm following flowchart.
March 7, 0 comment Read Full Article. This may take a second or two. Subscription pricing is determined by: The Fischer-Tropsch FT Synthesis Process is a catalyzed chemical reaction in which synthesis gas, a mixture of carbon monoxide and hydrogen, is converted into liquid hydrocarbons of various forms via the use of a reactor with cobalt or iron catalyst. OEM review is necessary to determine if the proposed SAJF is fit for purpose for use on aircraft and engines, and to identify the Phase 2 testing requirements.
The feedstock is gasified at high temperatures to degrees Celsius into carbon monoxide and hydrogen primarily synthesis gas or syngasand is then converted to long carbon chain waxes through the FT Synthesis Process. Advanced Combustion Tests Area 4: Work has been initiated to define advanced compositional test methods and other criteria and procedures necessary to ensure consistent quality and performance of AJFs produced to the generic annex.
ASTM International and OEM participation in the evaluation or approval procedure does not constitute an endorsement of the fuel or additive.
