This invention relates to a new process for making fatty acids directly from a feedstock consisting of phytoplankton in water without the need to a) thermally separate, dewater and dry the phytoplankton, and b) extract the immobilized lipids. Our method is much less expensive than the current practice of making fatty acids from phytoplankton, because we bypass the costly and energy intensive operations associated with a) dewatering and drying the biomass, and b) extracting the immobilized lipids. As such, this invention greatly enhances the economic viability of making biofuels and bioproducts from phytoplankton.

Fatty acids from phytoplankton

This invention provides a process for making ammonia from biomass. The biomass may be first reacted with oxygen and steam to generate a biosyngas comprising hydrogen (H) and carbon monoxide (CO) as the active components. The gasification step may be regulated to reduce the amount of methane in the biosyngas that may leave the gasifier.

This invention relates to a sulfur tolerant, dynamic, compact, lightweight fuel process and system that is capable of converting sulfur bearing carbonaceous fuels to hydrogen rich gases suitable for fuel cells or chemical processing applications. The process and system is based on the AHR and WGS reactions, followed by cleanup of byproduct sulfur-containing gases and carbon oxides that would otherwise poison the fuel cell electrocatalyst. Advantageously, this is accomplished via an ASMS and a methanator or an AWMR. The process and system preferably uses a special sulfur tolerant catalysts and hardware designs that enable the conversion in an energy efficient manner while maintaining desirable performance characteristics such as rapid start-stop and fast response to load change capabilities.

A method and apparatus determines an inbound traffic intensity of a visitable site, wherein the inbound traffic intensity factor is representative of a measure of meaningful visits to a visitable site in a given time period. The inbound traffic intensity factor is determined by obtaining visitor information including the number of visits to the visitable site during the given time period as well as the duration of each visit and using both the number visits and the time spent during each visit to quantify the traffic to the site during the time period.

Method for making time-sensitive determinations of traffic intensity for a visitable site

This invention relates to a composition for use in treating benign prostatic hyperplasia including a saw palmetto extract provided in an oral controlled release formulation which allows release of active ingredients in the intestinal tract and which allows the maintenance of therapeutic levels of active agents in the bloodstream for prolonged periods of time. This invention also relates to a composition for improving the efficacy of a saw palmetto extract, a method of treating benign prostatic hypertrophy, and a method of improving the efficacy of a saw palmetto extract treatment.

This invention relates to thermo-chemical remediation and decontamination of sediments and soils contaminated with organic contaminants as well as inorganic materials with subsequent beneficial reuse. Novel environmentally stable products of commercial value are produced when certain additives such as calcium and metal oxides are mixed with the contaminated materials. In the process, the mixture is heated to 1150.degree. C..about.1500.degree. C. to produce a molten reaction product with at least part of an excess amount of oxygen mixture or air is continuously bubbled through the melt in order to provide mixing and achieve high thermal destruction and removal efficiencies of the organic contaminants. The melt is then quickly quenched in moist air, steam, or water to avoid the transformation of the amorphous material into crystals. The inorganic contaminants such as chromium, nickel, zinc, etc. are incorporated and completely immobilized within the amorphous silicate network. Atmospheric emissions resulting from this process are nontoxic and capable of meeting currently specified health and environmental requirements.

The amorphous material can be pulverized to yield a powder which evinces cementitious properties either by reaction with alkali solution or by blending it with other materials to produce blended cements. The compressive strengths of the concretes made from the powder of the subject invention and blends thereof are comparable to, or greater than the ASTM requirements for general purpose concrete applications. The powder of the subject invention, blended cements, and concrete/mortar derived therefrom also easily pass the EPA TCLP leach test to achieve environmental acceptability.

An improved double tube reactor having a plurality of inner and outer tube assemblies each of the assemblies having a reaction annular volume between the inner tube and outer tube and a closed center plug within the inner tube forming an annular thermal exchange volume between the center plug and the inner tube to obtain desired temperature control of exothermic and endothermic catalytic chemical reactions. In one embodiment of the invention, the improved double tube reactor is used in a process for production of high purity methanol from process gas produced by steam reforming hydrocarbon feedstocks in a tube type reformer followed by removing substantially all CO.sub.2 and H.sub.2 O from the process gas, adjusting the H.sub.2 /CO molar ratio to about 2 when necessary, and feeding the adjusted process gas to a methanol synthesis reactor contacting a methanol forming catalyst not requiring CO.sub.2 activation at about 200.degree. to about 300.degree. C. to produce product gas comprising methanol, and recovering liquid methanol having purity greater than about 99.85% pure by cooling the product gas to a temperature below the boiling point of methanol and separating the liquid methanol from gaseous components of the product gas. In a preferred embodiment, process gas of H.sub.2 /CO molar ratio of about 2.0 to about 2.5 is passed through an annular thermal exchange volume between a center plug and an inner tube followed by passing the gas in contact with a catalyst in a catalyst bed between the inner tube and an outer tube of a double tube reactor assembly promoting the direct reaction of H.sub.2 and CO to product methanol.
