TL;DR: In this article, a methanol carbonylation reaction for the manufacture of acetic acid, [Rh(CO)_2Cl]_2 was adopted as catalyst, and metal salts of Sn、 Pb、 Cr、 Zr was used as additives.

TL;DR: In this article, X-ray diffraction, TPR (temperature programmed reduction) techniques are used to characterize the Co-Mo/CNT catalysts prepared by pore volume impregnation method.

TL;DR: In this article, the authors focused on the conversion of gasoline olefins to aromatics over ZSM-5 zeolite and showed that the catalytic performance of a modified nano-sized ZSM5 Zeolite is closely related to its crystal size, surface acidity and reaction conditions like temperature, weight-hourly-space- velocity (WHSV_(oil)) of oil feed and hydrogen-oil ratio (H_2/oil).

TL;DR: In this paper, a novel catalysts with active component of tungsten phosphide were prepared from the mixture of support γ-Al\-2_3 and Tungsten phosphate as precursor, and characterized by means of temperature-programmed reduction in highly-pure flowing hydrogen.

TL;DR: In this article, the deactivation of DME synthesis catalyst Cu-ZnO-ZrO_2/HZSM-5 derived from colloid sedimentation method was investigated.

TL;DR: In this article, the metallocene was grafted to the surface of a silica MCM-41 by using cyclopentadienyl sodium and ZrCl_4.

TL;DR: In this article, the preparation of ZnAlCe-hydrotalcite like-compounds[ZnAlce-HTLcs] was studied, and the properties of the synthesized compounds were characterized by XRD, FT-IR and ICP.

TL;DR: In this article, the aromatization of several compounds over superfine and microcrystal HZSM-5, such as octene-1, cyclohexane and n-octane, was investigated.

TL;DR: In this paper, the activating catalysis mechanisms of Zirconium and Hf promoters were presented concisely, and a series of PX oxidation experiments at different Zr and hafnium concentrations were carried out.

TL;DR: In this article, a series of transition metal (Cr, Mn, Fe, Co, Ni, Cu, Ag) oxide catalysts supported on MgO were prepared by impregnation method.

TL;DR: In this article, the MZSM-5 and MZ SM-5P catalysts of medium-pore zeolites ion-exchanged by various metal were studied under moderate pressure.

TL;DR: The results showed that 20% LaPO_4 was dispersed uniformly on Y Zeolite by microwave irradiation and the activity of CaY-LaPO-4 was higher than that of LaPO-3 as mentioned in this paper.

TL;DR: In this article, the authors characterized and analyzed carbon spices on Ni/γ-Al_2O_3 and Ni-Ce-Mn-Li/γγ-al-2O-3 catalysts surface and found that there are four types of carbon species: carbonate, contaminate carbon, carbide carbon and inactive carbon.
