Advantageously the internal surface is made of quartz or coated with quartz Advantageously the internal surface, made of silica (advantageously quartz) or coated with silica (advantageously quartz), is treated with HF before the conversion of methane to methanol. Advantageously the reaction is carried out in the absence in said reaction zone of any added material which measurably affects the rate of the reaction or the yield of the product. Advantageously the reactor is operated under a pressure from 1 to 7.5 MPa.Type: GrantFiled: July 4, 2008Date of Patent: July 10, 2012Assignee: Total Petrochemicals Research FeluyInventors: Hendrik De Winne, Pierre Jacobs, Bert Sels, Walter Vermeiren
