The invention relates to a reactor for the auto-thermal reforming of methane and carbon dioxide comprising a vertically oriented furnace body (1) provided with gas inlet means (12, 13) and gas outlet means (14), wherein (a) the furnace body (1) comprises from top to bottom mixing means (5), gas distribution means (2), a combustion chamber (6), a reforming reaction chamber (7) and a gas-collecting chamber (8) fluidly connected with gas outlet means (14); (b) the gas inlet means (12) comprises a gas nozzle (11) positioned at the top of the furnace body (1) and extends into combustion chamber (6) along the vertical longitudinal axis (15) of the furnace body (1) through mixing means (5) and gas distribution means (2); and (c) the gas distribution means (2) is positioned around the outlet end of the gas nozzle (11). The invention also relates to a process for the preparation of synthesis gas using the above reactor. In this process methane-comprising gas (CH4), carbon dioxide (CO2) and an oxygen-containing gas (O2) are fed into the auto-thermal reforming reactor and the heat released by the oxidation reaction between CH4 and O2 is provided as heat source to promote the reforming reaction between CO2 and CH4, thereby forming synthesis gas.

3. WOWO/2014/111310 - PROCESS FOR THE PREPARATION OF SYNTHESIS GAS24.07.2014
C01B 3/38
PCT/EP2014/050377SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ B.V.SUN, Yuhan
The invention relates to a process for the preparation of synthesis gas. Process for the preparation of synthesis gas by auto-thermal reforming of carbon dioxide and methane comprising the steps of (a) introducing a methane-comprising feed gas, carbon dioxide and an oxygen-containing gas into a carbon dioxide-methane auto-thermal reforming reactor comprising a bed of reforming catalyst; (b) mixing the methane-comprising feed gas, carbon dioxide and oxygen-containing gas; (c) reacting methane with oxygen in an oxidation reaction; (d) reacting methane with carbon dioxide in a reforming reaction in the presence of the reforming catalyst using the heat released in the oxidation reaction in step (c); and (e) recovering the synthesis gas produced in steps (c) and (d). The process realizes the self-supply of heat in the high temperature reforming reactor by utilizing the heat generated in the exothermic oxidation reaction between methane and oxygen in the endothermic carbon dioxide-methane reforming reaction. The invention, accordingly, not only solves the heating problems of the reforming reactor at high temperatures, but also decreases the energy consumption and operating cost of the system.

B01D 53/26
PCT/JP2014/050134MITSUBISHI HEAVY INDUSTRIES, LTD.INUI, Masayuki
In this dehydration device, a plurality of adsorption towers for alternately carrying out an adsorption process to adsorb moisture contained in CO2 gas, and a regeneration process to desorb adsorbed moisture, are provided in parallel on a CO2 gas supply line, and during intervals in which the adsorption process is carried out in predetermined adsorption towers, the regeneration process is carried out in other adsorption towers. In the dehydration device, a portion of the CO2 gas dehydrated by the adsorption towers currently in the adsorption process is heated by a regeneration gas heater and supplied to an adsorption tower (A) currently in the regeneration process, whereupon the CO2 gas supplied to the regeneration gas heater and the CO2 gas discharged from adsorption towers currently in the regeneration process undergo heat exchange by the regeneration gas heater. In the dehydration device, heat-exchanged CO2 gas discharged from an adsorption tower (62) currently in the regeneration process is cooled by a regeneration gas cooler, and condensed moisture is separated from the cooled CO2 gas, and returned to the adsorption towers. Consequently, the dehydration device can minimize the increase in utility consumption due to the regeneration process.
