TH3733B - The process of preparing synthetic gases from hydrocarbon-containing feed substances - Google Patents

Abstract

The process of preparing a synthetic gas from a hydrocarbon-containing feeder (for example, methane) consists of the following steps: Partially at high temperatures and pressures with steam to products containing H2 and CO, b) products from step a), and the rest of the feed was partially oxidized with accelerators. reaction With gases containing oxygen and c) removal of CO2 from the products obtained from step b)

Claims (6)

1. The process of preparing a synthetic gas from a feeder containing hydro-carbon. It consists of the following steps: (a) Hydrocarbons present in 50-99% volumetric feeders are partially converted by steam to products containing H2 and CO at high temperatures ranging from 400- 1500 c. Pressure ranging from 3-50 bar and at space velocity from 600-1350 liters of hydrocarbon-containing feedstock (At standard temperature and pressure) / l The remainder of the catalyst / h and from 3500-4500 liters of steam (at standard temperature and pressure) / liter of the catalyst / h (b) product from step A) and the remainder of the feed was given. There is some thermal oxidation that occurs with oxygen, at temperatures ranging from 600-1100 C, pressure from 10-50 bar, and the space velocity associated with the product in step b). From 5000-10000 l (at standard temperature and pressure) / l of catalyst / h and (c) CO2 removed from product obtained in step b) and at least some of the CO2 removed in step Step c) is directed to step a) and / or step b). 2. Process, as requested in claim 1, with almost all of the CO2 eliminated in Jon c) taken to Step a) and / or Step b). 3.Process as requested in claim 1 or 2, where part of the hydrocarbon-containing feeder is used in step a) and the remainder is lowered directly to step b). 4. Process for which one of Claims 1 to 3 is requested Where the hydrocarbon-containing feedstock was partially converted in step d) another step. At high temperatures and pressures with steam to a product containing H2 and CO, the product was partially oxidized with a catalyst in the process. E) another step, with oxygen-containing gases and CO2 removed from the products obtained from step e) in step f) in another step and taken to steps a) and b) at least step. One episode 5. The process of preparing a synthetic gas from a hydrocarbon-containing feeder, generally described earlier, with reference to the sample. 6. The synthetic gas produced in accordance with the procedure as requested by any of the above claims.
