David Sudolsky, President & CEO of Anellotech, explains that by targeting the production of renewable chemicals and fuels from non-food biomass, Anellotech’s sustainable technology Bio-TCat has completed its R&D program and the company is currently planning construction of its first licensed commercial plant. Anellotech also is advancing its new breakthrough plastics chemical recycling process. Plas-TCat uses plastic waste as a feedstock through the same technology platform.
Founded in 2008, Anellotech was set up to develop a technology platform to create more sustainable products. Demand for greener everyday household goods, such as food and drinks packaging – as well as more sustainable ways to power our transport, like biofuels – continues to rise.
Anellotech has created a pathway to 100% bio-based drop-in aromatic chemicals and fuels from non-food biomass. By using proprietary Bio-TCat technology, chemical producers and brand owners can meet environmental sustainability goals thanks to the process’ lower carbon footprint and cost-efficiency.

Creating an efficient, cost-competitive and scalable bio-based process is a significant challenge. However, Bio-TCat technology is making that goal a reality. Alongside development and licensing partners IFPEN and Axens, Anellotech is now planning for design and engineering of its first commercial plant. Engineering work has begun and the next phase of construction is planned for the second half of 2020. Anellotech also is moving forward to using plastic waste as a feedstock for chemical recycling through its new Plas-TCat process.

Innovative technology creating bio-based aromatics
Bio-TCAT技术可产生生物基苯,甲苯,二甲苯(BTX)以及较大的芳香族剂的混合物 - 所有这些都与石油衍生的同类物质相同。在生物键盘过程中制造的液体产品家族称为肛门剂,包括:

  • ‘AnelloMate BTX’, a naphtha containing over 90% bio-BTX
  • “厌食症蒸馏器”,中间和重型馏出物均碳氢化合物混合物。

AnelloMate products offer a unique opportunity as cellulosic-sourced biofuels with the same properties as conventional fuels, including fungibility in fuel distribution systems.

Bio-TCat’s product slate provides greater flexibility and the opportunity to serve dual product markets. If renewable chemicals-to-polymers markets are the targets, AnelloMate BTX can be separated to make high purity bio-based aromatic chemicals. If the goal is to make fuels, it makes a high-octane gasoline/petrol blendstock. In both cases, the Anellotech Distillate stream is used as bio-marine fuel, or it can be upgraded to make diesel or jet fuel blendstocks.

生物-​​TCAT热分解生物量,然后将催化转化为同一反应堆中的BTX。这个单步过程使用专有的沸石催化剂,Anellotech与Johnson Matthey共同开发了该催化剂,以产生商业吸引人的产量。

Many applications and uses
BTX aromatics produced using the Bio-TCat Process can be used in a range of chemical applications to make commodity plastics such as polyester (polyethylene terephthalate or ‘PET’), polystyrenes, polycarbonates, nylons, ABS (acrylonitrile-butadiene-styrene) and polyurethanes, which are used to manufacture consumer goods such as beverage bottles, food packaging, clothing, footwear, carpeting, automotive and electronic components. BTX component benzene is also used to produce LAB (linear alkyl benzene), a strong surfactant used in laundry detergents.
Anellotech also has developed MinFree technology, an innovative, biomass pre-treatment process. With patents pending, MinFree has been demonstrated to significantly reduce the mineral (ash) content of loblolly pine at a 20 metric ton/day scale. Month-long trials converting MinFree-treated, low-mineral pine into bio-BTX at Anellotech’s pilot plant showed extended, economic catalyst life.
MinFree is expected to provide similar results with other woody biomass like eucalyptus and hard woods as well as agricultural residues like cotton straw, sugarcane bagasse and corn stover. We believe these advances could provide expanded feedstock flexibility and performance to many different applications.
到目前为止,Bio-TCat芳烃生产强g loblolly pine feedstock from the southern United States. Loblolly pine is abundant, low-cost and there is an existing, highly-efficient supply chain for growing, harvesting and transporting millions of tons for industrial applications.
However, the MinFree and Bio-TCat processes can be adapted to use other non-food biomass inputs. Anellotech is now selecting and testing additional feedstocks for further commercialization.
By using Plas-TCat to recycle plastic waste, companies could produce aromatics and olefins directly and these products will be more valuable compared to producing straight pyrolysis oils. An expectation of valuable products with a high yield could potentially pay for plastic waste feedstock in countries without subsidized trash collection infrastructure. Anellotech’s pilot plant is already in place – only minor modifications would be needed to handle plastic feedstock instead of wood.
纺织品是通过新工艺Tex-TCAT探索的另一种替代原料,该过程还利用Anellotech技术平台。Under consideration for conversion are cotton fabrics, synthetic fabrics (polyester, nylon, Lycra/Spandex, etc) as well as blends to turn into valuable aromatics and other chemicals to use as a ‘drop-in’ replacement for the petroleum-derived aromatics used to make the same virgin synthetic fabrics, or biofuels.
Creating 100% bio-based PET bottle
另一个重点是商业化生物 - 帕西克(Anellotech)与世界领先的消费者饮料公司之一Suntory合作。生物 - 顺叶是制造100%基于生物的PET瓶所需的关键丢失组件。Suntory目前使用30%的Bio Pet用于其Tennensui品牌的矿泉水,但其目的是为Tennensui和未来其他可能的其他品牌制作100%基于生物的宠物。
A BTX sample produced at TCat-8 has already been converted into high-purity bio-paraxylene, and larger volumes are now being prepared to make a 100% bio-PET resin for prototype bottle manufacture and product testing. These high-purity bio-paraxylene test samples have met the ASTM international specifications for downstream derivatives including PET conversion. This will be the industry’s first production of bio-PET from continuous, cost-effective processing of non-food biomass.
Sustainable technology confirmed by LCA
Made from renewable feedstocks, Bio-TCat products enable significant GHG reductions when compared to identical chemicals currently made from crude oil. This was confirmed by Jacobs (Jacobs Engineering Group Inc.), who conducted an in-depth review of Anellotech’s greenhouse gas emissions (GHG) lifecycle analysis (LCA) using its industry-respected refinery and petrochemical process models.
The LCA compared Bio-TCat aromatics produced using sustainably-sourced loblolly pine feedstock from the southern United States, to petro-aromatics produced in the US Gulf Coast from three crude oils, which represented a range of carbon intensities. Jacobs employed their proprietary models for oil production, transportation and refining to estimate the carbon intensity of producing high-purity paraxylene and benzene products.
结果发现CO2emissions for producing paraxylene and benzene from pulpwood using Anellotech’s process are estimated to be 70–80% lower than emissions for identical petro-based chemicals made from crude oils. If Bio-TCat is configured to make renewable gasoline and distillate fuel blendstocks, the reduction potential exceeds 90% as fuels are burned to make energy.
Anellotech is seeking to extend its strategic collaborations and license Bio-TCat to customers who want to capitalize on the improved sustainability and competitiveness of its technology to build and operate commercial plants. Biomass suppliers, chemicals manufacturers, refiners, brand owners and others across the supply chain are welcome to enquire about joining the Anellotech alliance network.
Research programs for chemical recycling of waste plastic and waste clothing are underway. Strategic partner engagement is welcome for both development funding and complimentary expertise in the waste supply chain, and future commercial plant locations.
该公司将继续与其合作伙伴合作,以确保性能,交付和质量 - 必不可少的,因为Anellotech会移动不断地交付其第一个商业生物播放工厂。
