Abstract: In a first stage of a methane conversion system, at least some methane (CH4) in an input gas flow stream can be converted into C2 hydrocarbons, hydrogen gas (H2), and aromatics to provide a first processed stream. The conversion can be direct non-oxidative methane conversion (DNMC). At least some of the aromatics can be removed from the first processed stream to provide a second processed stream. In a second stage of the methane conversion system, at least some of the H2 can be removed from the second processed stream to provide a recycle stream. The recycle stream can be returned to the first stage of the methane conversion system for further conversion of methane and removal of aromatics and H2 products.

Abstract: The present invention relates to a method for chlorinating an aromatic compound and, more specifically, to a method for chlorinating an aromatic compound to prevent the phenomenon of decreased responsiveness due to foam generation, and to prevent counterflow of a fluid. By means of the method for chlorinating an aromatic compound according to the present invention, a plurality of column-type reactors are connected in series so that reaction products produced in a former reactor are inserted to a latter reactor, and chlorine gas is inserted in equal measure at the bottom of each reactor. Accordingly, a chlorination reaction occurs in each of the reactors, and hydrogen chloride gas generated in each of the reactors is exhausted from each of the reactors.

Abstract: A process for the epoxidation of propene involves reacting propene with hydrogen peroxide, in the presence of a methanol solvent and a shaped titanium zeolite epoxidation catalyst in a fixed bed reactor. The process then involves recovering methanol from the reaction mixture, treatment of the recovered methanol by passing it through a bed of an acidic ion exchange resin, and recycling the treated methanol to the epoxidation reaction; as well as regeneration of the acidic ion exchange resin. Catalyst breakage can be reduced or avoided by washing the regenerated bed of an acidic ion exchange resin with methanol until the methanol exiting the resin bed has an apparent pH higher than 1.8, before methanol treated with the acidic ion exchange resin is recycled to the epoxidation reaction.
