The renewa.le hydrogen genera.ion through etha.ol stea. reforming is one of the a.ticipa.ed a.ea. for susta.na.le hydrogen genera.ion. To elucida.e the role of Ni a.d Co with ZSM-5 support, ca.a.ysts were prepa.ed by wet impregna.ion method a.d etha.ol stea. reforming(eSR) wa. performed.

Pha.e-field simula.ion serves a. a. effective tool for qua.tita.ive cha.a.teriza.ion of microstructure evolution in single-crysta. Ni-ba.ed supera.loys during solidifica.ion nowa.a.s. The cla.sic unit cell is either limited to γdendrites a.ong crysta. orienta.ion or too idea. to cover complex morphologies for γ dendrites. a. a.tempt to design the unit cell for two-dimensiona.(2-D) pha.e-field simula.ions of microstructure evolution in single-crysta. Ni-ba.ed supera.loys during solidifica.ion wa. thus performed by using the MICReSS(MICRostructure evolution Simula.ion Softwa.e) in the fra.ework of the multi-pha.e-field(MPF) model,a.d demonstra.ed in a.commercia. TMS-113 supera.loy. The coupling to Ca.PHa.(Ca.cula.ion of PHa.e Dia.ra.) thermodyna.ic da.0} wa. rea.ized via.the TQ interfa.e a.d the experimenta. diffusion coefficients were utilized in the simula.ion. Firstly, the cla.sic unit cell with a.single γ dendrite a.ong crysta. orienta.ion wa. employed for the pha.e-field simula.ion in order to reproduce the microstructure ***, such simple unit cell wa. extended into the ca.es with two other different crysta. orienta.ions, i.e., a.d . Thirdly, for crysta. orienta.ions, the effect of γ dendritic orienta.ions a.d unit cell sizes on microstructure a.d microsegrega.ion wa. comprehensively studied, from which a.new unit cell with multiple γdendrites wa. proposed. The pha.e-field simula.ion with the newly proposed unit cell wa. further performed in the TMS-113 supera.loy, a.d the microstructure fea.ures including the competitive growth of γ dendrites,microsegrega.ion of different solutes a.d distribution of γ′ gra.ns, ca. be nicely reproduced.
