A process for recovering PHA-based chemical intermediates from biomass is schematically outlined in FIG. Likewise, when a biomass comprises 3-hydroxypropionate (3HP), the monomer component, β-propiolactone, can be modified to other three carbon products (C3 products, e.g. As used herein, the term “feedstock” refers to a substance used as a raw material in an industrial process. Poly-3HP was prepared by fermentation using a genetically modified E. coli strain specifically designed for production of poly-3HP from glucose syrup as a carbon feed source. Under the contemplated definitive agreements, Metabolix will buy the specialty PHAs produced at the Fort Dodge facility from CJ, and market and sell the materials to its commercial customers. In the first stage of the process, crotonic acid is converted to the butyl crotonate ester using an esterification catalyst known to those skilled in the art but could include acids, alkaline metal hydroxides, alkoxides and carbonates, enzymes and non-ionic bases, such as amines, amidines, guanidines and triamino(imino)phosphoranes. Metabolix and CJ CheilJedang Corporation to partner on new PHA production unit Metabolix, Inc., a USA-based advanced biomaterials company focused on sustainable solutions for the plastics industry, announced earlier today that it has entered into a Memorandum of Understanding ("MOU") with Korea-based CJ CheilJedang Corporation ("CJ"). 8. In certain embodiments, the catalyst is calcium hydroxide, ferrous sulfate heptahydrate, or sodium carbonate or mixture of these.

Fuel materials produced by this process are used for direct combustion or further treated to produce pyrolysis liquids or syngas. Ed., 42, p1900). 153:411-18 (1997); Valentin & Dennis, J. Biotechnol. PCT Publication No. 61/413,195, filed Nov. 12, 2010. The short-chain polymers are more crystalline—hard but brittle. Notice of Allowance for U.S. Appl. PHAs have a lot on their curriculum vitae that suggests they’re perfect for this moment. In the first stage, ethylene and 2-butene are first converted to propylene using a metathesis catalyst which is not sensitive to deactivation by ethylene such as Schrock's molybdenum-alkylidene or tungsten-alkylidene catalysts (Schrock et. The incoming gas/vapor stream from the pyrolysis/torrefaction chamber enters an interchanger, where the gas/vapor stream may be pre-cooled. Pyrolysis sample cups containing only switch grass and poly-3HP at 20% by weight were also prepared and analyzed for comparative purposes. 8 is a gas chromatogram of dry microbial biomass+P5HV+lime (5% by wt.) For example, substantially inert solvents include, without limitation, aromatic hydrocarbons, such as benzene, toluene, xylenes, etc. New processes for converting “natural” olefin products to useful biobased chemicals have recently been reported (J.

No. In certain embodiments, the methods further comprising recovering the monomer component, for example condensing or other recovery methods. In still other embodiments, the heating time duration is for a time between about 5 minutes and about 30 minutes, between about 30 minutes and about 2 hours, or between about 2 hours and about 10 hours or for greater that 10 hours (e.g., 24 hours). Several commercial processes are in use including fixed bed technology and fluid bed technology processes. come overnight. Lett. In previous embodiments, the conversion of PHAs to corresponding chemicals of interest by low temperature degradation was described. The calcination temperature is chosen to be below the melting point of the substrate but above its decomposition or phase transition temperature. It is therefore obtained by catalytic cracking of long chain hydrocarbons left during refining of crude oil. The conversation centered on the company’s Mirel amorphous PHA biopolymers, and of course, on the memorandum of understanding the company recently signed with Korea-based CJ CheilJedang Corporation for a strategic commercial manufacturing arrangement for these specialty PHAs. Such an immobilized catalyst may be used in a flow process. Thus the amount of monomer in the monomer component can be about 70% by weight, about 71% by weight, about 72% by weight, about 73% by weight, about, 74% by weight, about 75% by weight, about 76% by weight, about 77% by weight, about 78% by weight, about 79% by weight, about 80% by weight, 81% by weight, about 82% by weight, about 83% by weight, about 84% by weight, about 85% by weight, about 86% by weight, about 87% by weight, about 88% by weight, about 89% by weight, about 90% by weight, 91% by weight, about 92% by weight, about 93% by weight, about 94% by weight, about 95% by weight, about 96% by weight, about 97% by weight, about 98% by weight, about 99% by weight, or about 100% by weight. The process is normally carried out in reactors such as hearth furnaces, shaft furnaces, rotary kilns or more recently fluidized beds reactors. In yet another aspect of the invention a continuous biorefinery process for production of acrylic acid from PHA biomass using a multiple tandem catalysis reaction protocol is described. Strains of E. coli containing the phb genes on a plasmid have been developed to produce P(3HB-3HV) (Slater, et al., Appl. In certain aspects, these monomer components, are intermediates for further processing to other reaction products or monomer components for example, monomer components that are commodity chemicals. Renew your membership, and continue to enjoy these benefits. In Winchester, Kentucky, Danimer is building what will be the world’s largest PHA plant when it starts up in October with about 8,000 t per year of capacity.
