Abstract: 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.

Abstract: Systems and methods are provided for oligomerization of olefins to distillate boiling range products while also recycling naphtha boiling range olefins as part of the feed. By performing the olefin oligomerization while also recycling naphtha boiling range olefins, it has been discovered that the resulting distillate boiling range products can have an unexpected improvement in diesel combustion quality, such as an unexpected improvement in cetane rating. In order to manage coke formation and maintain consistent activity profile for the oligomerization catalyst, the reaction can be performed in a moving bed reactor. Additional temperature control can be maintained by the recycling of the naphtha boiling range portions of the oligomerization product back to the reactor.

Abstract: A method includes containing an algae slurry within a cultivation vessel, introducing the algae slurry into a dissolved air floatation (DAF) system, and operating the DAF system in a low-recovery mode and thereby selectively removing impurities from the algae slurry. Algal biomass is then harvested from the algae slurry after removing the impurities from the algae slurry.

Abstract: Devices, methods, and systems employing a multivariate optical computing sensor comprising a multivariate optical element calibrated to independently measure an electromagnetic spectral pattern of a cultivation characteristic of an algae stain in a cultivating algae water slurry and a detector for receiving output signals indicative of the cultivation characteristic. The cultivation characteristic may include, for example, total organic carbon, total carbohydrate, or fatty acid methyl esters.

Abstract: A system for growing algae in a slurry, includes a pond having an inlet and an outlet and a plurality of contiguous elongate channel segments coupled fluidically in sequence between the inlet and the outlet, and the inlet is located at an elevation higher than outlet to allow gravity to flow the slurry from the inlet to the outlet. The system further includes a separation device fluidically coupled to the outlet to receive and separate algae from the slurry.

Abstract: 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.

Abstract: Systems and methods are provided for conversion of a combined feed of oxygenates (such as methanol or dimethyl ether) and olefins to a high octane naphtha boiling range product with a reduced or minimized aromatics content. The oxygenate conversion can be performed under conditions that reduce or minimize hydrogen transfer. Optionally, a catalyst that further facilitates formation of branched paraffins can be used, such as a catalyst that has some type of 12-member ring site available on the catalyst surface.
