제목 Steam Reforming of Decahydronaphthalene over Ca modified Ni-based Hydrotalcite Catalyst
초록 Hydrogen is an ideal fuel because it is clean and simplifies the system integration. But infrastructures for hydrogen supply have not yet been established. For the mobile or stationary production of hydrogen, reforming of hydrocarbons is a practical method.Diesel has higher gravimetric and volumetric hydrogen density than LNG or LPG and well-estabilished delivery infrastructure. In spite of these advantages, reforming of diesel has not been widely studied because of some problems such as severe coke formation, sulfur poisoning, etc.
In the study, steam reforming(SR) of decahydronaphthalene(Decalin; C10H18), which is a representative major component of diesel was investigated in a fixed-bed reactor system with the Steam/C ratio of 3,Gas Hourly Space Velocity(GHSV) of 10,000 h-1 at the temperature range from 973 K to 1173 K by employing Ca modified Ni-based hydrotalcite catalysts (CaxNiMg/Al; x=0.01~1). Decalin was fully converted above 973 K with no condensable products.It was found thatCaxNiMg/Al was maintained its catalytic activityduring58 h operation. Catalysts before and after SR were characterized by XRD, TEM, TPR and CO pulse chemisorption.
