Synergetic Mode for Grassland Ecological Management and Animal Husbandry Development in Northern Tibet

Hasbagan Ganjurjav, Hu Guozheng, Gao Qingzhu, Jiangcun Wangzha, Danjiu Luobu,Can Muyou, Basang Wangdui, Yang Fuyu, Wei Xuehong, Yang Yongping

Strategic Study of CAE 2019, Volume 21, Issue 5,   Pages 93-98 doi: 10.15302/J-SSCAE-2019.05.013

Abstract:

Northern Tibet Plateau is an important ecological security shelter for China and a base of animal husbandry with plateau characteristics. However, grassland degradation is threatening the functioning of alpine grasslands and brings great challenges to ecological protection and animal husbandry development. In this study, we analyzed the current situation of ecological protection and animal husbandry development in the Northern Tibet Plateau, summarized the factors affecting the functions of alpine grasslands in this region, and introduced a synergistic mode for grassland ecological protection and animal husbandry development. A series of measures were also proposed to enhance the ecological functions of the alpine grasslands and upgrade the grassland-based animal husbandry, including ecological restoration of degraded grasslands, optimizing grazing management, artificial forage cultivation, developing a“low grass and high grazing” mode (i.e., planting grass in farming areas of low altitude and raising livestock in pastoral areas of high altitude), and half barn-feeding in winter. This study is hoped to provide scientific and technological support in ensuring national ecological security and increasing income of herdsmen.

The cooperation effect of Ni and Pt in the hydrogenation of acetic acid

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 3,   Pages 397-407 doi: 10.1007/s11705-021-2076-4

Abstract: The catalytic hydrogenation of carboxylic acid to alcohols is one of the important strategies for the conversion of biomass. Herein, a series of Ni-doped PtSn catalysts were prepared, characterized and studied in the hydrogenation of acetic acid. The Ni dopant has a strong interaction with Pt, which promotes the hydrogen adsorption, providing an activated hydrogen-rich environment for the hydrogenation. Meanwhile, the presence of Ni also improves the Pt dispersion, giving more accessible active sites for hydrogen activation. The cooperation of Pt and Ni significantly promotes the catalytic activity of the hydrogenation of acetic acid to ethanol. As a result, the catalyst with 0.1% Ni exhibits the best reaction activity, and its space time yield is twice as that of the PtSn/SiO2 catalyst. It provides a meaningful instruction on the catalyst design for the carboxylic acid hydrogenation.

Research on the flotation of kaolinite using a series of dodecyl tertiary amines

Cao Xuefeng,Liu Changmiao, Hu Yuehua

Strategic Study of CAE 2011, Volume 13, Issue 1,   Pages 93-97

Abstract:

The flotation performances of four tertiary amines (DRN, DEN, DPN and DBN) on kaolinite were studied in this paper. All the four tertiary amines show very good flotation effects on kaolinite, and DEN does the best, with the highest flotation recovery of 92 %. In the acid pH scale, four tertiary can float kaolinite well because their cationics absorb onto the surface of kaolinite by electrostatic force; with the increasing of pH, the content of cationics was decreased to result in the lower flotation recovery. On the basis of Zeta potential, the surface of kaolinite is mainly electro-negative in the whole pH region, and its Zeta potential is remarkable increased after kaolinite was affected by four tertiary amines. Both the results of FT-IR spectra and Zeta potential show that four tertiary amines are absorbed onto the surface of kaolinite by electrostatic force. The flotation differences of four tertiary amines are due to the electronic effects and space steric effects of the substituents belonging to N atom in the amine molecule.

Keywords： tertiary amine     kaolinite     flotation     electrostatic effect     electronic effect     space steric effect
