Abstract
In a GTL process of producing various kinds of hydrocarbon oils from natural gas, provided is improved heat efficiency in the case of using a steam reforming process or a carbon dioxide reforming process in the reforming. The process includes producing a synthesis gas by converting the natural gas and at least one of steam and carbon dioxide into a synthesis gas through a tubular reformer filled with a reforming catalyst, producing Fischer-Tropsch oil by subjecting the produced synthesis gas to a Fischer-Tropsch reaction, and upgrading in which the Fischer-Tropsch oil is subjected to hydrotreatment and distillation to produce various kinds of hydrocarbon oils, in which excess heat generated in the synthesis gas production is recovered, and the recovered heat is used as heat for at least one of hydrotreatment and distillation in the upgrading.
