2450 results about "Renewable resource" patented technology

A renewable resource is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. Renewable resources are a part of Earth's natural environment and the largest components of its ecosphere. A positive life cycle assessment is a key indicator of a resource's sustainability.

Fuel Composition

Compositions and methods for forming hydrocarbon products from triglycerides are disclosed. In one aspect, the methods involve the thermal decomposition of fatty acids, which can be derived from the hydrolysis of triglycerides. The thermal decomposition products can be combined with low molecular weight olefins, such as Fischer-Tropsch synthesis products, and subjected to molecular averaging reactions. Alternatively, the products can be subjected to hydrocracking reactions, isomerization reactions, and the like. The products can be isolated in the gasoline, jet and / or diesel fuel ranges. Thus, vegetable oils and / or animal fats can be converted using water, catalysts, and heat, into conventional products in the gasoline, jet and / or diesel fuel ranges. These products are virtually indistinguishable from those derived from their petroleum-based analogs, except that they can have virtually no aromatic, sulfur or nitrogen content, they are derived, in whole or in part, from renewable resources, and can also be derived from domestically available coal and / or natural gas.

Wax for hot melt adhesive applications

Waxes prepared from hydrogenated plant oils, such as palm and soybean, are used as substitutes for petroleum derived waxes in hot-melt adhesive compositions. Unlike petroleum-derived or synthetic waxes, adhesive compositions comprising these waxes, which are obtained from naturally derived, renewable resources, achieve adhesion performance similar to conventional adhesives containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 120-165 degrees F. (Mettler Drop Point). These waxes comprise a triglyceride whose fatty acids are predominantly stearic acid (C18). The naturally derived waxes are used as an alternative to petroleum and synthetically derived waxes in the manufacture of adhesives used to bond paper, wood, glass, plastic and metal in a variety of manufacturing operations.

Inflatable heliostatic solar power collector

Increased utilization of solar power is highly desirable as solar power is a readily available renewable resource with power potential far exceeding total global needs; and as solar power does not contribute to pollutants associated with fossil fuel power, such as unburned hydrocarbons, NOx and carbon dioxide. The present invention provides low-cost inflatable heliostatic solar power collectors, which can be stand-alone units suitable for flexible utilization in small, medium, or utility scale applications. The inflatable heliostatic power collectors use a reflective surface or membrane “sandwiched” between two inflated chambers, and attached solar power receivers which may be of photovoltaic and / or solar thermal types. Modest concentration ratios enable benefits in both reduced cost and increased conversion efficiency, relative to simple prior-art flat plate solar collectors.

Nanocomposite biomaterials of nanocrystalline cellulose (NCC) and polylactic acid (PLA)

A new approach is conceived for the development of sustainable biomaterials comprising nanocrystalline cellulose (NCC) and polylactic acid (PLA) nanocomposites. The invention deals with advancing a method based on in situ ring opening polymerization of L-lactide in the presence of NCC particles to form NCC-PLA supramolecular nanocomposite materials. This material is hydrophobic and compatible with a wide range of synthetic and natural polymers. NCC-PLA nanocomposites have enhanced functionality (e.g. gas barrier), rheological and mechanical performance, as well as dimensional stability (i.e. less hygroexpansivity) relative to PLA. They are made from entirely renewable resources, and are potentially biocompatible as well as recyclable. NCC-PLA supramolecular nanocomposites can be suspended in most organic solvents or dried to form a solid substance. They can be processed using conventional polymer processing techniques to develop 3-dimensional structures, or spun into fibres, yarns or filaments.

Power generation optimization in microgrid including renewable power source

A microgrid including a renewable power source is optimized by treating the renewable source as operating in an isochronous mode, and by decomposing the optimization process. A renewable capability is defined for the renewable source to enable treatment of the renewable source as operating in an isochronous mode. The renewable capability may be based on a power rating of the renewable source. An objective function of the microgrid optimization problem may then be optimized while treating the renewable source as operating in an isochronous mode. A penalty factor may be applied to avoid power shortage.
