REFORMING METHOD FOR PRODUCING SYNTHETIC GAS AND INSTALLATION FOR REALISING SAID METHOD Russian patent published in 2010 - IPC C01B3/38 

FIELD: chemistry.

SUBSTANCE: invention relates a method of obtaining synthetic gas. The method involves a preliminary reforming step on which a process mixture (18), which contains a mixture of hydrocarbons (14) and water vapour (16), undergoes preliminary catalytic conversion to obtain a partial conversion product (22), and a main reforming step on which the partial conversion product (22) undergoes final conversion to obtain synthetic gas (12). The preliminary reforming step is carried out in a pseudoisothermic mode. A portion of the partial conversion product is heated and used on the preliminary reforming step as fluid working medium for indirect heat exchange. The installation (10) includes series-arranged section (28) for preliminary reforming, which has a first reaction zone (20), and a main reforming section (30) which has a second reaction zone (24). The first reaction zone (20) is a catalyst bed in a pseudoisothermic reactor (34) fitted with a heat exchange device (36). The installation also has a heat recuperation device (38), whose input is linked to the catalyst bed and the output to the heat exchange device.

EFFECT: high hydrocarbon conversion degree at the preliminary reforming step using a simple and cheap method.
