3183 results about "Biodiesel" patented technology

Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, ethyl, or propyl) esters. Biodiesel is typically made by chemically reacting lipids (e.g., vegetable oil, soybean oil, animal fat (tallow)) with an alcohol producing fatty acid esters.

Synthetic and biologically-derived products produced using biomass produced by photobioreactors configured for mitigation of pollutants in flue gases

Certain embodiments and aspects of the present invention relate to photobioreactor apparatus designed to contain a liquid medium comprising at least one species of photosynthetic organisms therein, and to methods of using the photobioreactor apparatus as part of a production process for forming an organic molecule-containing product, such as a polymeric material and/or fuel-grade oil (e.g. biodiesel), from biomass produced in the photobioreactor apparatus. In certain embodiments, the disclosed organic molecule/polymer production systems and methods, photobioreactor apparatus, methods of using such apparatus, and/or gas treatment systems and methods provided herein can be utilized as part of an integrated combustion and polymer and/or fuel-grade oil (e.g. biodiesel) production method and system, wherein photosynthetic organisms utilized within the photobioreactor are used to at least partially remove certain pollutant compounds contained within combustion gases, e.g. CO2 and/or NOx, and are subsequently harvested from the photobioreactor, processed, and utilized as a source for generating polymers and/or organic molecule-containing products (e.g. fuel-grade oil (e.g. biodiesel)) and/or as a fuel source for a combustion device (e.g. an electric power plant generator and/or incinerator).

Integrated photobioreactor-based pollution mitigation and oil extraction processes and systems

Integrated systems including a photobioreactor system designed to contain a liquid medium comprising at least one species of phototrophic organism therein, and a facility associated with extracting and / or processing oil extracted from mixtures of oil and solid material, such as an oil sands facility, are described. Processes for using a photobioreactor system as part of a gas-treatment process and system able to at least partially remove certain undesirable pollutants from a byproduct gas stream produced by an oil sands facility are also described. Examples of such pollutants that may be removed include compounds contained within combustion gases, e.g., CO2 and / or NOx. These pollutants processed with the photobioreactor system, and, in some embodiments, biomass produced with the photobioreactor system may be utilized to produce a fuel source (e.g., biodiesel) and cutting stock for further operation of or use in the oil sands facility. Such uses of certain embodiments can provide an efficient means for recycling carbon, thereby reducing CO2 emissions, fuel, and / or cutting stock requirements for a given quantum of energy produced. In addition, in some cases the photobioreactor can be integrated with a holding pond and waste heat from the oil extraction process can be used to maintain the photobioreactor temperature and / or provide energy for other processes. Accordingly, embodiments described herein can improve the overall environmental and economic profile of the oil sands facility.

Fuel cell system with integrated fuel processor

InactiveUS20070122667A1MinimizesMaximize heat utilizationHydrogenOxygen/ozone/oxide/hydroxideBiodieselWater balance
A fuel cell system with fuel processor for integration with a marine vessel propulsion system. The system includes an auto thermal reactor that is the fuel processor for producing hydrogen from a fuel source. The fuel source is preferably ethanol or biodiesel or a mixture thereof, but can also be a sulfur containing fuel like petrodiesel of JP-8. The system further includes a gas-water shift reactor for further production and concentration of the hydrogen from the auto thermal reactor output. The system also includes a hydrogen permeable membrane separator for generating suitable quantities of essentially pure hydrogen to the fuel cell. The system also includes an oxygen permeable membrane separator for concentrating oxygen and reducing nitrogen to improve the partial pressure of hydrogen in subsequent fuel processing steps. The system contemplates the use of a Polymer Electrolyte Membrane (PEM) fuel cell. The system minimizes preheating of catalysts or other components to the extent just needed to initiate the fuel processor. To that end, heat sources and sinks of the system and associated usage systems are matched so as to minimize heat collection, storage and distribution systems. Water is recycled within the system to the extent necessary to maintain a water balance in the fuel processor and the fuel cell stack(s). The system includes cooling of the fuel cell stack(s) and integrated heat recovery with exothermic and endothermic catalysts. The fuel processor/fuel cell system components are configured to conform to and take advantage of the available space and limitations, such as the space constraints and opportunities associated with a marine vessel.
