ABSTRACT
Ganzi Tibetan Autonomous Prefecture is the birthplace of Tibetan medicine of southern school, also rich in natural resources of Chinese and Tibetan medicine (CTM). As the pillar industry of Ganzi prefecture, CTM shows a trend of improvement of overall services, growing of the number of companies and increasing scale of industries. However, the CTM industry in Ganzi prefecture still has some shortcomings. This article reviewed the development and existential problems of CTM industry of Ganzi prefecture. In addition, the article carries on relevant thinking through literature review and discussion and analysis. It is believed that CTM industry of Ganzi prefecture faced with the conflict between environmental protection and the development of CTM industry, small scale of CTM industry, inadequate expertise and insufficient product innovation. This article gave some feasible suggestions, such as coordinated development of cultural tourism and medical industry, establishment of high efficient mode to promote producing-learning-research development, enhancement of quality standardization of CTM industry, with a purpose to guarantee the quality transmission of each step.
ABSTRACT
A naphtha catalytic reforming unit with four reactors in series is analyzed. A physical model is proposed to describe the catalytic reforming radial flow reactor. Kinetics and thermodynamics equations are selected to describe the naphtha catalytic reforming reactions characteristics based on idealizing the complex naphtha mixture by representing the paraffin, naphthene, and aromatic groups by single compounds. The simulation results based above models agree very well with actual operation unit data.
