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:
In a process for performing steam reforming of a feed gas (12) comprising methane in a reforming reactor (30) containing a reforming catalyst, to produce a synthesis gas, heat is provided to the reforming reaction by combustion (32) of a fuel in the presence of a combustion catalyst. The fuel consists at least partly of methane, and the process also comprises adding hydrogen to the fuel, and changing the proportion of hydrogen in the fuel in accordance with changes in the activity of the combustion catalyst. The hydrogen may be obtained from the synthesis gas, for example with a membrane (42). Adding hydrogen and optionally also carbon monoxide to the fuel can obtain a smoother and more consistent temperature distribution in the reactor (30) despite the decreasing activity of the combustion catalyst.

摘要:
The invention relates to a method for the parallel production of hydrogen (3) and of one or a plurality of carbon-containing products (8). In the method, hydrocarbons (2) are introduced into a reaction chamber (R) and are thermally decomposed into carbon and hydrogen in the presence of a carbon-rich granulated material (W). The invention is characterised in that at least a portion of the thermal energy necessary for the decomposition of the hydrocarbons is introduced into the reaction chamber (R) via a gaseous heat transfer medium.
摘要:
The formation of pollutants in a hydrocarbon reformer is reduced by use of flue gas recirculation. In typical systems and methods, a hydrocarbon reformer has air intake from an air intake fan where the hydrocarbon reformer produces flue gas exhaust. A portion of the flue gas exhaust is fed into an induced draft fan, wherein a flue gas recirculation ("FGR") fan draws a portion of the flue gas exhaust located downstream of the induced draft fan. The portion of the flue gas is drawn towards an air intake conduit downstream of the air intake fan, which reduces a flame temperature within the hydrocarbon reformer and reduces the formation of NOX.
