NOVELTY - Converting methane to methanol comprises: combining gaseous methane with water vapor carrying hydrogen peroxide in a closed reaction chamber; providing a metal cation chemical in the chamber to catalyze the chemical reaction; elevating the temperature of the chamber slightly to facilitate the chemical reaction; the reactive oxygen species provided by the hydrogen peroxide replaces a hydrogen atom on the methane molecule with a hydroxyl molecule, converting vaporized methane molecules to vaporized methanol molecules; and the methanol vapor is condensed to stable liquid methanol.    USE - The methanol is useful as vehicle fuel.    ADVANTAGE - The methanol is an environmentally compatible and efficient vehicle fuel. The methanol has lower combustion emissions of greenhouse gasses, evaporative hydrocarbons and particulate pollutants, yet has high energy content. The methanol can even be converted into boiling grade gasoline if necessary. The process is simple in construction and effective in production. The process provides a direct, one-step chemical conversion, where the methane from hydrogen peroxide diluted in water vapor, which oxidize the methane molecule to a methanol molecule in a one-step chemical conversion. The methane-containing natural gas is a clean and effective alternative energy resource.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for either a methane-to-methanol conversion apparatus comprising: a reactor having a rotating mixing cell with valving properties; injecting methane and water vapor carrying hydrogen peroxide into the reactor's mixing cell during each rotation cycle; coating the interior surfaces of the mixing cell chamber with a metal cation catalyst; elevating the mixing cell temperature slightly by the rotation friction of the apparatus; converting in the mixing cell the methane vapor into methanol vapor and exporting such methanol vapor from the mixing cell later in each rotation cycle; and condensation of methanol vapor to liquid methanol outside the mixing cell, such methanol liquid being stable at ambient temperature and pressure; or a closed loop duct where incoming feed gases are mixed and circulated by a fan; an inlet port for methane, and an inlet port for water vapor; an oxygen release screen interposed into the flow duct; one or more catalytic conversion cartridges interposed into the flow duct; such conversion cartridge having an outer frame housing one or more internal conversion screens; the oxygen release screens and conversion screen materials fabricated of woven or nonwoven fibrous webs, or expanded mesh; and such oxygen release screens and catalytic conversion screens having three dimensional porous colloidal dry chemical matrix coatings applied to the outer surface of their filter screen material in order to trap and present humectants and metal cation catalysts necessary for the process reactions.
