CAAFI – Focus Area – Fuel Qualification

This produces a C15 hydrocarbon molecule called farnesene, which after hydroprocessing to d404, can be used as a blendstock in jet fuel. ASTM International and OEM participation in the evaluation or approval procedure does not constitute an endorsement of the fuel or additive. The hydrocarbons are cracked and isomerized, creating a synthetic jet fuel blending component.

The OEMs are solely responsible for approval of a fuel or additive in their respective engines and airframes. 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. This standard is also available to be included in Standards Subscriptions. OEMs review the report and approve the fuel to move on to Tier 3 and Tier 4 testing in Phase 2 with specific testing requirements.

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. Air Force and the U. Mark Rumizen Contact us: Nearly 30, articles in our online library! Recent Tweets Tweets by AdvancedBiofuel. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.


An example is assessment of incidental materials on fuel properties. Please first log in with a verified email before subscribing to alerts.

This may take a second or two. Occasional Research Highlights — on-going. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Standard Practice for Qualification and Approval of New Aviation Turbine Fuels and Fuel Additives

The current ASTM D Evaluation Process for getting a fuel approved for commercial use includes the following three phases also see figure below:. Subscription pricing is determined by: These approaches have the potential to convert the carbon or hydrocarbon content of various feedstocks using biological fermentation or microbial conversion or thermochemical pyrolysis, hydrothermal liquefaction, catalytic conversion, etc.

The project astmm six components:.

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. Establish Your Product as a Viable Aviation Fuel Zstm new fuel producer must demonstrate the viability of their fuel for aviation i. Final balloting at the committee level occurs when all subcommittee level comments are addressed.


Military list only those fuels and additives that are mutually acceptable to all OEMs. Standards Subsctiption may be the perfect solution. A variety of CAAFI stakeholders, including government agencies, fuel producers, aircraft and engine manufacturers, and airlines participate on the CQ Team. 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.

Notice We are not accepting donations from people or companies in Florida due to unfair reporting requirements and fees not imposed by any other state.

The project includes six components: As the voice of the U. Combustion Model Development and Evaluation Area 5: Add to Alert PDF.

The results of these efforts will be posted here when available. Your Alert Profile lists the documents that will be monitored. D40054 Version s – view previous versions of standard.

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 d404 the generic annex. 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. The approval process is detailed below. British Petroleum Oil Spill:
