20130082211 | PROCESS FOR THE PREPARATION OF SYNTHESIS GAS - Process for the preparation of synthesis gas from an essentially dry hydrocarbon feedstock (1) comprising olefins, hydrogen and carbon monoxide, the process comprising the steps: (a) selectively hydrogenating the olefins in the hydrocarbon feedstock at a temperature between 60 to 190° C. (2) to obtain a hydrogenated hydrocarbon feedstock comprising hydrogen, carbon monoxide and saturated hydrocarbons (3; (b) adding steam (4) to the hydrogenated hydrocarbon feedstock; (c) performing a water gas shift reaction in the presence of steam on the hydrogenated hydrocarbon feedstock (6) to obtain a shifted, hydrogenated hydrocarbon mixture; (d) converting the shifted, hydrogenated hydrocarbon mixture (8) to obtain a synthesis gas. | 04-04-2013 |
20140135409 | PROCESS FOR REFORMING HYDROCARBONS - The invention relates to a process for the production of synthesis gas by the use of autothermal reforming in which tail gas from downstream Fischer-Tropsh synthesis is hydrogenated and then added to the autothermal reforming stage. | 05-15-2014 |
20150152019 | PROCESS FOR CONVERSION OF NATURAL GAS TO HYDROCARBON PRODUCTS AND A PLANT FOR CARRYING OUT THE PROCESS - A process for the conversion of natural gas to hydrocarbon products comprises the steps of (a) mixing natural gas with a small amount of hydrogen, (b) purifying the mixture from (a) in a feed purification section to obtain purified natural gas, (c) mixing the purified natural gas from (b) with steam to obtain the desired steam-to-carbon (S/C) ratio, (d) mixing the natural gas/steam mixture from (c) with the tail gas from the downstream Fischer-Tropsch synthesis or a part thereof in a syngas section and converting the mixture into a synthesis gas, (e) cooling the synthesis gas from (d) and condensing out the process water from it, (f) leading the dry synthesis gas from (e) to a carbon dioxide removal section, where the CO | 06-04-2015 |
