METHOD FOR STARTING UP PRE-REFORMING STAGE Russian patent published in 2018 - IPC C01B3/38 

FIELD: technological processes.

SUBSTANCE: invention relates to a method for starting up a pre-reforming stage, as well as an integrated reforming plant configured to carry out this method. Method for starting up a pre-reforming stage includes supplying an activation stream containing methanol and water, to the pre-reforming stage, converting the activation stream during interaction with a catalyst of the pre-reforming stage, discharging a second gas stream from the pre-reforming stage and feeding it to the main reforming stage, discharging a third gas stream from the main reforming stage, and partially recirculating said stream to the pre-reforming stage. Integrated reforming plant comprises at least one pre-reforming reactor, a main reforming reactor, a desulphurisation reactor, a hydrogen separation unit downstream of the main reforming reactor, a dosing device and pipelines for feeding the activating stream to the pre-reforming reactor.

EFFECT: disclosed method makes it easier to start up an integrated reforming plant and can be performed without expensive and rarely used equipment and only with operational materials that are stored easily and with little risk.
