Reaction kinetics modeling for lithium and cobalt recovery from spent lithium-ion batteries using acetic acid

引用

International Journal of Minerals,Metallurgy and Materials 2019年第1期26卷 98-107页

作者： Hendrik setiawan Himawan Tri Bayu Murti Petrus Indra Perdana Sustainable Mineral Processing Research Group Department of Chemical Engineering Faculty of Engineering Universitas Gadjah Mada

Lithium and cobalt recovery from spent lithium-ion batteries(LIBs) is a major focus because of their increased production and usage. The conventional method for recycling spent LIBs using inorganic acids produces harmful byproducts. In this work, the leaching agent was substituted with a less expensive and more environmentally friendly alternative—acetic acid—and a mathematical model was developed to describe the kinetics of the recovery process. The variables used were the pH value, temperature, H_2O_2 concentration, and the solid-to-liquid(S/L) ratio. The mathematical model used was the shrinking core model, which was modified to accommodate an equilibrium reaction. The experimental results show that the rate of recovery of Li and Co over time was only affected by temperature. The leaching behaviors of Li and Co were found to oppose each other. An increase in temperature resulted in increased recovery of Li but decreased recovery of Co because of the product-favoring endothermic reaction of Li and the reactant-favoring exothermic reaction of Co. The product of Li has a lower entropy value than the reactant as a free-moving ion, whereas the product of Co leaching has a higher entropy value as a stiff crystal complex. Thus, temperature conditioning is a pivotal factor in the leaching of spent LIBs.

People used to find and interpret objects from a clear optical picture or image, but single image can’t provide sufficient information for identification. Then again, first difficulties when we’re starting image fusion comes from the understanding point of what is the object or content in the image. Multi-sensor image fusion system can overcomes the limitations of a single sensor fusion system by combining the images from these sensors to form a composite image. Every image provided by these different sensors contains specific information of the given scene based on the properties of *** are various method used for making image fusion, but JPEG is a wide known image type has a process that’s widely used the lossy image compression form that centers around Discrete Cosine *** research is designing a platform with two cameras mounted at s o m e distance and also with angle parallel to acquire image that is showered with light source. The thesis propose was to construct an image fusion realization system based on multivision platform design, that is low cost with such proficiency.

Particle formation of hydroxyapatite precursor containing two components in a spray pyrolysis process

引用

Frontiers of Chemical Science and Engineering 2014年第1期8卷 104-113页

作者： W. Widiyastuti Adhi setiawan Sugeng Winardi Tantular Nurtono Heru Setyawan Department of Chemical Engineering Institut Teknologi Sepuluh Nopember Kampus ITS Sukolilo Surabaya 60111 Indonesia Politeknik Perkapalan Negeri Surabaya Kampus ITS Sukolilo Surabaya 60111 Indonesia

The particle formation mechanism of hydroxyapatite precursor containing two components, Ca（OOCCH3）2 and （NH4）2HPO4 with a ratio of Ca/P = 1.67, in a spray pyrolysis process has been studied by computational fluid dynamics （CFD） simulation on the transfer of heat and mass from droplets to the surrounding media. The focus included the evaporation of the solvent in the droplets, a second evaporation due to crust formation, the decomposition reaction of each component of the precursor, and a solid-state reaction that included the kinetic parameters of the precursor regarding its two components that formed the hydroxyapatite product. The rate of evaporation and the reacted fraction of the precursor both increased with temperature. The predicted average size of the hydroxyapatite particles agreed well with the experimental results. Therefore, the selected models were also suitable for predicting the average size of particles that contain two components in the precursor solution.

Activity of tamarindus indica pulp water extract in high carbohydrate diet rats as a treatment for obesity and insulin resistance

Obesity is often identified as a nutritional disorder, and this condition continues to be one of the most important yet preventable health hazards. It may be a complex group of diseases and should be characterized as a syndrome that results from an imbalance between energy intake and expenditure. Furthermore, obesity is associated with several diseases such as diabetes mellitus, atherosclerosis, cardiovascular diseases, osteoarthritis, and hypertension. In previous studies, we found that in Asia, especially in the Asean region, carbohydrates are heavily represented in the diet. Therefore, we used a high carbohydrate diet to induce obesity in rats. The aim of this study was to evaluate the potency of Tamarindus indica pulp as an anti-obesity agent in a high carbohydrate diet animal model. The antiobesity effect was evaluated in this in vivo model at doses of 75 mg/kg·bw and 225 mg/kg·bw. Treatment was started in week 3 and week 9, and biochemical characteristics were measured every 3 weeks. In the end of the study period, insulin resistance and adiponectin levels were measured. TIWE(Tamarindus indica water extract) at a dose of 75 mg/kg·bw showed better efficacy than at a dose of 225 mg/kg·bw, and treatment started on week 3 was better than treatment started on week 9. TIWE has an anti-obesity effect associated insulin resistance by increasing adiponectin levels and insulin sensitivity, which can impact body weight, triglyceride levels, blood glucose levels, and body fat.

作者： Chandra setiawan President University Supervisory Board of the President University Foundation Board of the General Assembly of the International Confucian Association

1. Introduction According to Report No. 22, titled“Religion and Its Disciples Throughout the World,” published by the United Nations in 1956, the number of Confucian disciples worldwide reached 300,290,500,ranking fourth after Catholicism, Islam,and Hinduism. Lewis Hodous (1967)stated,“Confucianism was established as the state religion by Emperor Wudi(140-87 BCE) and retained this position till 1912.” Scientific literature indicates that the influence of Confucius’ teachings in Indonesia started at the end of the prehistoric period.
