Method of reforming hydrocarbons

Patent ·
OSTI ID:6717337

Japan Gasoline Co., Ltd.'s new gasification approach avoids the need for an excess of steam to maintain catalyst activity when gasifying hydrocarbon feeds of different kinds (such as naphtha, kerosene, LP-gas, etc.) within one combined reaction system. The method introduces a mixture of hydrocarbons into the reaction zones of two or more catalyst beds distributively while introducing the whole amount of the steam into the reaction column of the first stage, thus augmenting the ratio of the steam to the mixture of hydrocarbons within the respective reaction zones. A mixture consisting of steam and hydrocarbons whose mean molecular weight is relatively small is introduced to the nickel-containing catalyst bed for the first stage at a temperature range of 662/sup 0/--1022/sup 0/F (350/sup 0/--550/sup 0/C). The resulting product is mixed with hydrocarbons whose mean molecular weight is larger than that of the preceding hydrocarbon--along with steam, if necessary--and is introduced to the nickel-containing catalyst bed at a temperature in the range of 572/sup 0/--1022/sup 0/F (300/sup 0/--550/sup 0/C) for the second stage.
