Methods and systems for efficient culturing of algae in open ponds are described.

High yield algal biomass production without concentrated COsupply under open pond conditions

Systems, methods, and materials for pyrolyzing vegetable oil feedstocks to obtain high yields of various products are described.

High-yield production of fuels and petro- and oleo-chemical precursors from vegetable oils and other liquid feedstocks in a continuous-flow pyrolysis reactor with or without catalysts

Methods and systems for efficient culturing of algae in open ponds. Further, the methods include a method for culturing algae in an open pond medium that is free of any concentrated supply of CO, and no concentrated source of COis used to supply carbon for culturing the algae. Also, the algae are cultured in the open pond which has a pH above 9.5. In addition, the open pond medium has incorporated therein an inorganic carbon buffer at a specified concentration under conditions for obtaining an increased biomass. Also, the pH above 9.5 permits sufficient increased fixation of atmospheric CO2 into the open pond medium.

Facile methods for high-yield furfural and HMF production from biomass sugars are described. The methods generally involve converting the biomass sugars in high yield to their ketose isomers, resulting in furan production under low temperature and pressure conditions with efficient recycling of the process streams.

A concise method of producing nylon 11, 12, or 13 precursors from oleic acid or an ester of oleic acid is described. The method involves cross-metathesis reactions as the key C&#x2014;C bond formation step. Subsequent steps are provided to convert the metathesis product to the corresponding nylon precursors. Also provided are the products of the method.

Methods and systems for the isomerization and fermentation of xylose and hexose sugars using an immobilized enzyme system capable of sustaining two different pH microenvironments in a single vessel are disclosed. Bilayer particles are dispersed in a mixture comprising an ionic borate source and xylose. The bilayer particles have a first region with a first enzymatic activity comprising xylose isomerase and a pH of 6 or above, and a second region having a second enzymatic activity at an acidic pH.

System for simultaneous isomerization and fermentation of sugars

Provided herein is a method of producing C11, C12, and C13 nylon precursors from oleic acid or esters of oleic acid, the method involving amide formation, ring-closing metathesis, and hydrogenation. Further provided are the products of the method described. Provided herein is a method for producing a lactam, the method comprising the steps of converting oleic acid or an ester of oleic acid into an amide having a general formula of H3C&#x2014;(CH2)rCH&#x2550;CH&#x2014;(CH2)rCONR&#x2014;(CH2)n-CH&#x2550;CH2, wherein n is 1, 2, or 3, and R is either hydrogen or benzyl; subjecting the amide to a ring-closing metathesis reaction to produce an intermediate having a general formula of &#x2014;(CH2)rCONR&#x2014;(CH2) n-CH&#x2550;CH2-, wherein n is 1, 2, or 3, R is either hydrogen or benzyl, and both ends are connected to each other; and hydrogenating the intermediate to produce a saturated lactam. In certain embodiments, the saturated lactam has a formula of &#x2014;NH&#x2014;(CH2) 10-CO&#x2014;.
