Oxidative Halogenation of C1 Hydrocarbons to Halogenated C1 Hydrocarbons

An oxidative halogenation process involving contacting methane, a C1 halogenated hydrocarbon, or a mixture thereof with a source of halogen and a source of oxygen, at a molar ratio of reactant hydrocarbon to source of halogen in a feed to the reactor greater than 23 / 1, and / or at a molar ratio of reactant hydrocarbon to source of oxygen in a feed to the reactor greater than about 46 / 1; in the presence of a rare earth halide or rare earth oxyhalide catalyst, to produce a halogenated C1 product having at least one more halogen as compared with the C1 reactant hydrocarbon, preferably, methyl chloride. The process can be advantageously conducted to total conversion of source of halogen and source of oxygen. The process can be advantageously conducted with essentially no halogen in the feed to the reactor, by employing a separate catalyst halogenation step in a pulse, swing or circulating bed mode. The production of methyl halide can be integrated into downstream processes for manufacture of valuable commodity chemicals.

Passive Electrostatic CO2 Composite Spray Applicator

An electrostatic spray application apparatus and method for producing an electrostatically charged and homogeneous CO2 composite spray mixture containing an additive and simultaneously projecting at a substrate surface. The spray mixture is formed in the space between CO2 and additive mixing nozzles and a substrate surface. The spray mixture is a composite fluid having a variably-controlled aerial and radial spray density comprising pressure- and temperature-regulated propellant gas (compressed air), CO2 particles, and additive particles. There are two or more circumferential and high velocity air streams containing passively charged CO2 particles which are positioned axis-symmetrically and coaxially about an inner and lower velocity injection air stream containing one or more additives to form a spray cluster. The axis-symmetrical CO2 particle-air streams are passively tribocharged during formation, and the spray clustering arrangement creates a significant electrostatic field and Coanda air mass flow between and surrounding the coaxial flow streams.
