摘要： A pass or tube or a section thereof or “U” bend in a coil in a paraffin cracker having section having a pore size in the metal substrate from about 0.001 to 0.5 microns over coated with a dense metal membrane permits the permeation of one or more of H2, CH4, CO and CO2 from cracked gases moving the reaction equilibrium to the production of ethylene and reduces the load on the down-stream separation train of the steam cracker.

摘要： A process for preparing methanol by a methanol synthesis reaction of carbon dioxide with hydrogen may involve a distillation step and a condensation step following the synthesis of a crude methanol. A volatile component and water may be separated off from a methanol-containing product stream, and a gas stream containing a volatile component that has been separated off may be discharged at least partially as offgas. At least part of the gas stream that has been separated off may be recirculated into the methanol synthesis reaction. A plant for preparing methanol can store or utilize electric power generated from renewable energy sources and provide facilities for discharging the offgas stream, which can be purified by catalytic after-combustion. Alternatively, the plant can be configured without discharge of an offgas substream, or the offgas streams are so small that they can be released without treatment into the environment at a suitable position.

摘要： A process for recovering a steam cracking feed from FCC absorber off-gas comprising ethylene, ethane and heavier hydrocarbons and light gases involves removing hydrogen, nitrogen, sulfur species, carbon monoxide/dioxide, methane and other impurities from the off-gas. An absorption zone is upstream of an acetylene selective hydrotreating reactor to remove sufficient hydrogen sulfide that can poison the selective hydrotreating catalyst but leave sufficient sulfur in the feed stream to prevent temperature runaway.

摘要： A methanation reactor for reacting dihydrogen with a carbon-based compound and producing methane. The reactor has a hollow body configured to receive a fluidized bed of catalytic particles, an inlet for each carbon-based compound and dihydrogen, and an outlet for methane and water. A water inlet is provided to inject liquid-phase cooling water into the fluidized bed. When each carbon-based compound is a gas, the reactor has at least one water-injection nozzle and at least one gas injection nozzle for a gas consisting of the carbon-based gas and dihydrogen, and at least one water-injection nozzle positioned below the gas-injection nozzle. The flow rate of water introduced into the hollow body can depend on the temperature measured in the reactor.
