摘要： Methods, compositions and kits for masking and subsequent removal of oil, grease, rust and other stains from a variety of rough solid surfaces, including, but not limited to stone, concrete, asphalt, stucco brick, and ceramic. The methods include coating the stains with an opaque or translucent thin film of a composition that makes the stain practically indistinguishable against the background, exposing the coated stain to the elements, such as, sunlight, air, moisture, resulting in spontaneous transformation, degradation and subsequent removal of the stains from the solid surfaces. The compositions include a photocatalyst by itself or the photocatalyst combined with at least one of, a sensitizer, a dopant, a mediator, a co-reagent, a pigment and a binder. The role of a photocatalyst is to produce highly reactive species or radicals and initiate the degradation of a stain upon exposure to elements, such as, sunlight, air and ambient humidity. Artificial light sources can be used instead of sunlight.

摘要： This invention relates to a novel process for sustainable CO2-free production of hydrogen and carbon by thermocatalytic decomposition (or dissociation, pyrolysis, cracking) of hydrocarbon fuels over carbon-based catalysts in the absence of air and/or water. The process is applicable to any hydrocarbon fuel, including sulfurous fuels. Combination of a catalytic reactor with a gas separation unit allows to produce high purity hydrogen (at least, 99.0 v %) completely free of carbon oxides. In a preferred embodiment, sustainable continuous production of hydrogen and carbon is achieved by both internal and external activation of carbon catalysts. Internal activation of carbon catalyst is accomplished by recycling of hydrogen-depleted gas containing unsaturated and aromatic hydrocarbons back to the reactor. External activation can be achieved via surface gasification of carbon catalysts by hot combustion gases during catalyst heating. The process can conveniently be integrated with any type of fuel cell.
