METHOD FOR PRODUCING SYNTHETIC GAS

摘要

A method for reforming hydrocarbon-containing feed gas into synthesis gas, involving processing of the feed gas by pre-reforming at least partially converting one or more higher hydrocarbons into methane, and heating the feed gas by exothermic catalytic partial oxidation of hydrocarbons before the introduction thereof into the main reforming zone, and, subsequent to the pre-reforming, reforming the pre-reformed product with the addition of a controlled quantity of an oxidizing agent.

主权项

1. A process for producing synthesis gas from hydrocarbonaceous feed gas, the process comprising:
prereforming the feed gas comprising a higher hydrocarbon, in a prereforming zone, to at least partly convert the higher hydrocarbon into methane; heating the feed gas, before introduction of a pre-reformed effluent into a main reforming zone, by exothermal catalytic partial oxidation of the hydrocarbon under partial oxidation conditions and by adding a controlled amount of an oxidizing agent, to obtain the pre-reformed effluent; and reforming the pre-reformed effluent, to obtain a synthesis gas comprising a carbon oxide and hydrogen, in the main reforming zone.
