et al [14] show that CaO catalyzes and ameliorates the cracking of heavy hydrocarbon rich in the aromatic compounds during the biomass gasification process. The investigation results of ZHOU [15] show... of the catalyst and believed that the C-H rupture expedited the generation of the positive carbon ion, which would benefit the activation of the catalyst. ZHOU et al [18] found that there were many......
="ChDivSummary" name="ChDivSummary">The effects of substitution of Al for Co on magnetic and magnetocaloric properties of MnCo1-xAlxGe (x=0.00, 0.03, 0.05, 0.08, 0.10, 0.13, 0.15, and 0.20) compounds have been investigated by X-ray diffraction (XRD) and magnetization measurements. XRD exhibits that MnCo1-xAlxGe compounds crystallize in the orthorhombic TiNiSi-type structure for x≤0.03 and in the hexagonal......
