A submersible device submersible within an algae slurry contained within a pond of an algae bioreactor, the submersible device including a drive motor operable to actuate one or more driven devices that move the submersible device within the pond, a circulation device operable to circulate the algae slurry through the submersible device and discharge the algae slurry back into the pond from a discharge port provided on the submersible device, and a computer system that controls operation of the drive motor and the circulation device.

Autonomous submersible device for algae growth and collection

The present disclosure relates to algae cultivation including the integration of liners for large-scale open algal biomass to facilitate algae facility commercial scale-up operations. Liners include those having a first portion having a first thickness and a second portion comprising a second thickness, wherein the first thickness and the second thickness are different. Liners also include those having a first portion having a first thickness, a second portion comprising a second thickness, and a third portion comprising a third thickness, wherein the first thickness, the second thickness, and the third thickness are different.

Systems and methods comprising open algae cultivation liners

A system includes an algae bioreactor that contains an algae slurry, a heat exchanger in fluid communication with the algae bioreactor to receive the algae slurry from the algae bioreactor and heat and increase a pressure of the algae slurry, and one or more valves and a flash vessel in fluid communication with a discharge of the heat exchanger to flash the algae slurry and create steam and algae biomass. A separator receives the algae biomass from the flash vessel and separates oils from the algae biomass to generate a biofuel.

Solar steam explosion of algae

A method includes containing an algae media within a contactor, introducing a stream of natural gas comprising up to 80 wt % carbon dioxide (CO) into the contactor, contacting the natural gas on the algae media and thereby allowing the algae media to consume COfrom the natural gas, and discharging a stream of natural gas comprising 2 wt % or less COfrom the contactor.

Upgrading and enrichment of gases through algae photobioreactors

Disclosed herein are processes and systems that utilize olefin cross metathesis of triglycerides to produce jet fuel such as hydrocarbons with carbons numbers from C9 to C16. Jet range hydrocarbons may include paraffins, naphthenes, and aromatics with carbon numbers from 9 to 16 (C9-C16), and isomers thereof. The process described herein is versatile and may be suitable for producing jet range hydrocarbons from many different grades and sources of triglycerides. Further, the process described herein may be selective to jet range hydrocarbons which may result in increased yield as compared to hydrocracking or other processes for producing jet range hydrocarbons from triglycerides.

High yield jet fuel from mixed fatty acids

A method for producing jet range hydrocarbons may include reacting at least a portion a fatty acid stream comprising C18:1 free fatty acid with ozone in an ozonolysis unit to form at least a C18:1 ozonide intermediate; introducing the C18:1 ozonide intermediate into a reactor, wherein at least a portion of the C18:1 ozonide intermediate is reacted with a reductive agent to produce oxidized products comprising azelaic acid and nonanoic acid; and introducing the oxidized products into a hydrotreating unit, wherein at least a portion of the oxidized products is hydrotreated to produce a paraffin product comprising nonane.

High yield jet fuel and chemicals from ozonolysis of triglycerides

Apparatuses including offshore porous floating bioreactors for containing algae water slurries in a saltwater environment. The porous floating bioreactors include a top portion and a bottom portion. At least a portion of the top portion is composed of a first transparent material and at least a portion of the bottom portion is porous. The offshore porous floating bioreactors may be deployed in a saltwater environment to facilitate one or both of cultivation or lipid induction of an algae water slurry contained therein.

Floating photobioreactors for algae biofuel production and devices and methods related thereto

A system includes a photobioreactor that provides a channel configured to contain an algae slurry, a duct positioned adjacent the channel and configured to convey a gas, and a barrier separating the duct from the channel and providing one or more apertures to allow a portion of the gas to be injected into the algae slurry from the duct.

Bioreactor with integrated flue gas distribution

A system for growing algae includes a pivot arm pivotally coupled to a pivot connection positioned in a pond containing water and algae, and a mixing device coupled to the pivot arm and extending into the pond to mix the water and the algae as the pivot arm rotates.

Pivot arm systems for mixing in bioreactors

A system for growing and harvesting algae biomass includes a photo-bioreactor suitable for algae growth in water and a filter unit in fluid communication with the photo-bioreactor. An algae slurry, when at least partially contained within the photo-bioreactor, generates hydrostatic fluid pressure that exclusively drives the algae slurry to the filter unit and discharges a permeate.

Photo-bioreactor and filter unit integration for separation of algae biomass

Isobutanol may be converted into predominantly Colefin oligomers under specified conditions. Such methods may comprise: contacting a feed comprising isobutanol with a zeolite solid acid catalyst having a MWW framework under conditions effective to convert the isobutanol into a product comprising Colefin oligomers, wherein n is an integer having a value of two or greater and about 80 wt. % or greater of the Colefin oligomers are larger than C.

Oligomerization of isobutanol in the presence of MWW zeolite solid acid catalysts

Systems and methods are provided for upgrading catalytic slurry oil. The upgrading can be performed by deasphalting the catalytic slurry oil to form a deasphalted oil and a residual or rock fraction. The deasphalted oil can then be hydroprocessed to form an upgraded effluent that includes fuels boiling range products.

Hydroprocessing of deasphalted catalytic slurry oil

Systems and methods are provided for solvent deasphalting of steam cracker tar. The resulting deasphalted oil produced from the steam cracker tar can then be hydroprocessed, such as hydrotreated and/or hydrocracked in a fixed bed reactor. The solvent deasphalting can correspond to a mild or trim deasphalting or can correspond to solvent deasphalting at higher solvent to oil ratios. Performing a trim deasphalting can reduce or minimize the amount of deasphalting residue that is formed as a product from the deasphalting process.

Deasphalting and hydroprocessing of steam cracker tar

Systems and methods are provided for upgrading aromatic refinery fractions by performing trim alkali metal desulfurization. The alkali metal desulfurization can be performed by mixing the aromatic refinery fraction with alkali metal in finely dispersed solid and/or molten form, such as molten sodium. The aromatic nature of the refinery fraction can potentially be beneficial for the desulfurization reaction mechanism. The aromatic refinery fractions can correspond to fractions that have been previously processed to remove metals. Because only trim desulfurization is being performed, the desulfurization can be performed under relatively mild alkali metal desulfurization conditions that result in a reduced or minimized amount of feed conversion.
