The Research on Catalyst and Application in the Pre-reforming of Light Oil;

as adiabatic pre-reforming, pre-reformer, reforming heat exchanger and combination autothermal reformer, can improve the operational conditions of primary tube reformer, save fuel and reduce the energy consumption of the whole ammonia plant.

The operation shows that a good hydrodesulfurization of feedstock will lead to a higher activity of pre-reforming and reforming catalysts and ensures the long-term operation of hydrogen generation plant.

Investigation of adiabatically catalytic prereforming process of light oil;

ype CN-14 catalyst has been developed for prereforming of light oil to obtain methane-rich gas.

In this paper,the application of Z501 naphtha steam pre reforming catalyst in hydrogen production units is presented.

The structure,material,strength calculation and welding seam structure of pre reformer are introduced.

In view of traditional shaft furnace process of sponge iron,the new viewpoint was put forward,in which sponge iron could be produced by non preinverting shaft furnace with coke oven gas other than natural gas.
