摘要： A system is provided for reforming a hydrocarbon feedstock. The system comprises: first prereformer units and first preheating unit arranged upstream a bayonet tube steam methane reformer. The system is arranged to provide a temperature of the heated partially-reformed process stream at the inlet of the bayonet tube steam methane reformer of at least 600° C. and a temperature of the gas at the bottom of the bayonet steam methane reformer tubes of at least 800° C. This arrangement allows higher bayonet tube inlet temperatures, with reduced risk of increased metal dusting. A process is also provided for reforming a hydrocarbon feedstock in the system of the invention.
