Ensyn Receives Key Regulatory Approval for its Renewable Gasoline  

Tuesday, November 24, 2015

Approvals Now in Place for Ensyn’s Renewable Diesel and Gasoline

Dr. Robert Graham, Chairman of Ensyn Corporation (Ensyn), is pleased to announce that Ensyn has been granted a key regulatory approval from the U.S. Environmental Protection Agency (EPA) for its renewable gasoline product, RFGasoline. This approval, pursuant to Title 40 CFR Part 79 promulgated under the Clean Air Act, is required for the sale of RFGasoline into U.S. commerce.

This approval follows the recently announced Part 79 approval of Ensyn’s renewable diesel product, RFDiesel.

RFGasoline, a drop-in gasoline transportation fuel, is created by processing Ensyn’s renewable crude (RFO), a liquid cellulosic feedstock for refiners, with customary petroleum feedstocks in conventional petroleum refineries (RFO Coprocessing). Ensyn is developing and commercializing RFO Coprocessing in a strategic alliance with Honeywell UOP, a global leader in technology solutions for the refining industry.

Ensyn’s RFO is produced by processing non-food solid biomass, including wood residues, with Ensyn’s RTP™ technology. Technology licensing, engineering services and supply of equipment is being provided to RTP projects by Honeywell UOP through Envergent Technologies, a joint venture between Honeywell UOP and Ensyn.

Veronica May, vice president and general manager of UOP’s Renewable Energy and Chemicals business, said, “We are very pleased that RFGasoline has received this important regulatory approval. With Part 79 regulatory approvals now in hand for both RFDiesel and RFGasoline, Ensyn and Honeywell UOP can accelerate the commercial introduction of RFO Coprocessing, an attractive solution for refiners wishing to easily integrate cellulosic feedstocks into their operations in a cost-effective manner.”

Ensyn is advancing its RFO Coprocessing business with UOP and an array of first-class, global industry leaders. The Part 79 registration process involved a number of these industry leaders. The liquid RFO feedstock was produced at one of Ensyn’s commercial facilities and shipped to Brazil. Using Petrobras proprietary FCC coprocessing technology, 400 gallons of coprocessed diesel were produced in a technical collaboration between Petrobras and the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). The gasoline fraction was shipped to a major international oil company in the U.S. for initial evaluation and preparation for the Part 79 test. The final RFGasoline product was then shipped to Southwest Research Institute (SwRI) in San Antonio, Texas, where independent Part 79 testing was conducted.

“This approval is another key step in the commercialization of our refinery coprocessing business,” stated Dr. Graham. “Refiners can now proceed with commercial deployment of RFO Coprocessing and sell both key products, renewable gasoline and renewable diesel, into US commerce. Ensyn and Honeywell UOP can now expedite offtake negotiations with refiners while Ensyn and its project partners proceed with expansion of RFO production capacity in order to meet demand.”

RFO Coprocessing

RFO Coprocessing is an innovative and game-changing approach for the production of renewable gasoline and diesel. Conventional biofuel solutions are based on producing blend fuels, such as ethanol and biodiesel, that are blended with finished fuels post-refining. In contrast, Ensyn’s coprocessing solution provides refiners with a renewable feedstock and the result is ASTM specification transportation fuel, not a blend. In addition, the RFO Coprocessing solution is based on conversion of non-food, cellulosic feedstocks to fuels, avoiding competition with food markets.

Ensyn & UOP

Ensyn and UOP have a broad technology alliance that covers the production of RFO, as well as the commercialization of RFO Coprocessing. Ensyn and UOP have established a joint venture known as Envergent Technologies LLC that licenses Ensyn’s biomass conversion technology (RTP®) for certain applications and provides performance guarantees to RFO projects that UOP, Ensyn and its partners are developing worldwide. In addition, Ensyn and UOP are collaborating on the commercialization of RFO Coprocessing. Under this collaboration, UOP is interfacing with refiners and facilitating a seamless integration of RFO into their refineries.

About Ensyn Corporation

Ensyn is a leader in the production of cellulosic liquid biofuels produced from wood residues and other non-food biomass. Ensyn has more than 25 years of commercial operations and has produced more than 40 million gallons of liquid fuels and chemicals from wood residues. Ensyn’s key liquid product, known as RFO™, is a heating fuel and can be used as renewable crude in refineries for the production of ASTM spec gasoline and diesel. Ensyn owns and operates a commercial RFO production facility in Ontario, Canada that supplies RFO for sale to heating clients in the US and Canada. Additional RFO production capacity is under development in Aracruz, Brazil and at other locations in Canada and the US. Ensyn is executing its business plan in conjunction with key strategic relationships, including UOP, Fibria Celulose SA and Chevron Technology Ventures.
