The reaction zone consists of an alloy containing, by weight, 66-82% nickel, 14-18% chromium, and 4-6% aluminum. This alloy, which has already been preoxidized, may be covered, at least in the reaction zone, with at least one layer formed by an oxide of at least one metal and/or at least one metal carbide and/or at least one metal nitride and/or at least one metal silicide. The invention finds application for vapor-phase cracking and dehydrogenation of hydrocarbon charges.

The heating means are adapted to heat the passages by successive independent cross sections substantially perpendicular to the axis of the reactor. In a second part 8 (towards the opposite end) adjoining the first part, the reactor further comprises means 9 for cooling the effluent, connected to the means for supplying cooling fluid. The reactor also has means for introducing a gas containing hydrogen into the space surrounding the heating means inside the sheaths 4, at an appropriate pressure.

The heaters heat the passages by successive independent cross sections substantially perpendicular to the axis of the reaction. Towards the outlet end, the reactor further comprises an injector for supplying cooling fluid, which cools the effluent. The reactor also has a hydrogen inlet for introducing a gas containing hydrogen into the space surrounding the heaters inside the sheaths 4 at an appropriate pressure. The reactor and the sheaths 4 are designed so that hydrogen is diffused from inside the sheaths to outside them and can then be diluted in the process gas.

    摘要: The invention concerns a process for upgrading olefinic gasolines containing C.sub.5 hydrocarbons, but free of C.sub.4 hydrocarbons, by etherification. It is characterized in that the tertiary olefins of the charge are reacted (1 and 2) with methanol; the reaction effluent being then extracted (3) with water, in order to separate an aqueous phase containing the major part of the unreacted methanol from a hydrocarbon phase containing the major part of the formed ethers. The aqueous phase is then introduced in a distillation zone (4) where water is separated from methanol and recycled to the extraction zone (3), whereas methanol is recycled to the etherification zone (1 and 2).
