The invention discloses an attapulgite argil powder with an air purifying function. The technical scheme is as follows: the attapulgite argil powder with an air purifying function is prepared from high-viscosity attapulgite clay, an attapulgite constant-humidity conditioner, a natural mineral adsorbing / filtering agent, Cacumen Biotae, aluminum silicate fiber and polyacrylamide. The attapulgite argil powder is prepared by the following steps: pulverizing the materials, soaking and aging to obtain a wet mixture, extruding the wet mixture into a strip, airing the strip, pulverizing to obtain powder, and packaging to obtain the finished product. The attapulgite argil powder has favorable cohesive property, plasticity, thixotropy, fire resistance and thermal stability; the pottery prepared from the attapulgite argil powder with an air purifying function contains a great deal of micropores and activated carbon, thus, has the characteristics of low shrinkage, no cracking or deformation and favorable adsorbability, and can effectively adsorb formaldehyde, ammonia, benzene and other harmful substances in the air, thereby protecting the environment and improving good health of people. The invention is suitable for producing pottery artware with an air purifying function.

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 organism therein, and to methods of using the photobioreactor apparatus as part of a hydrogen production process and system configured to generate hydrogen with and / or from biomass produced in the photobioreactor apparatus. In certain embodiments, the disclosed hydrogen 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 hydrogen 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 fuel source for generating hydrogen and / or as a fuel source for a combustion device (e.g. an electric power plant generator and / or incinerator).

A fluid storage and dispensing system comprising a vessel for holding a fluid at a desired pressure. The vessel has a pressure regulator associated with a port of the vessel, and set at a predetermined pressure. A dispensing assembly, e.g, including a flow control means such as a valve, is arranged in gas / vapor flow communication with the regulator, whereby the opening of the valve effects dispensing of gas / vapor from the vessel. The fluid in the vessel may be constituted by a liquid which is confined in the vessel at a pressure in excess of its liquefaction pressure at prevailing temperature conditions, e.g., ambient (room) temperature. A phase separator such as a gas / vapor-permeable liquid-impermeable membrane, may be associated with the regulator, as a barrier to flow of liquid into the regulator, when the contained fluid in the vessel is in a liquid state.

An apparatus for forming liquid hydrocarbons from solid coal. The coal is pulverized to provide a particulate coal feed, which is then extruded to provide a hollow tube of compressed coal supported inside of a support tube. A clay feed is extruded to provide a hollow tube of compressed clay supported inside of the coal tube and a combustible fuel is burned inside of the clay tube. The temperature of combustion is sufficient to fire the extruded clay and pyrolyze the extruded coal to produce hydrocarbon gases and coal char. The support tube has holes for releasing the hydrocarbon gases, which contain suspended particles formed during combustion. The suspended particles are removed from the hydrocarbon gases to provide clean gases, which are passed through an ionizing chamber to ionize at least a portion thereof. The ionized gases are then passed through a magnetic field to separate them from each other according to their molecular weight. Selected portions of at least some of the separated gases are mixed, and the mixed gases are cooled to provide at least one liquid hydrocarbon product of predetermined composition. Portions of the separated gases may also be mixed with the coal char and other input streams, such as waste plastics, and further treated to provide other hydrocarbon products.

Various systems, methods, and devices are provided for focusing particles suspended within a moving fluid into one or more localized stream lines. The system can include a substrate and at least one channel provided on the substrate having an inlet and an outlet. The system can further include a fluid moving along the channel in a laminar flow having suspended particles and a pumping element driving the laminar flow of the fluid. The fluid, the channel, and the pumping element can be configured to cause inertial forces to act on the particles and to focus the particles into one or more stream lines.
