2022年3月1日 Optimization of the extraction process for reducing aromatic and/or polyaromatic compounds is of primary interest in crude oil refining. Several solvents are described for carrying out such operations (furfural, N-methyl-pyrrolidone -NMP-, dimethyl-sulfoxide -DMSO-, ) and experimental data and model description are required for the

Although the process is very simple, it can induce thermal degradation, hydrolysis, and water solubility of some fragrance constituents (Reverchon and Marco 2006). Supercritical fluid extraction has also been introduced to extract citronella essential oil (Silva et al. 2011). However, this method has drawbacks such as high investment costs and
2021年8月1日 The review includes the occurrence of rubidium in various resources, and the processes and mechanism of rubidium extraction from mineral (lepidolite, zinnwaldite, pollucite, kaolin, muscovite and biotite) and brine (salt lake and seawater) resources. It is expected that the review can provide insights for the efficient utilization of the
2018年9月20日 The abilities of different types of extractants to extract and separate Rb and K were evaluated at a phase ratio (O/A) of 1:1, extractant concentration of 1 mol/L, and contact time of 2 min using xylene as a diluent. As shown in Table 3, except t-BAMBP, other extractants do not extract Rb and K satisfactorily. The difference between the

oil extraction, isolation of oil from animal by-products, fleshy fruits such as the olive and palm, and oilseeds such as cottonseed, sesame seed, soybeans, and peanuts. Oil is extracted by three general methods: rendering, used with animal products and oleaginous fruits; mechanical pressing, for oil-bearing seeds and nuts; and extracting with volatile
2017年9月29日 Fossils fuels come from plant and animal matter that died millions of years ago. Soil and sediment built up over time, putting pressure on the material and forcing oxygen out. This plant matter turned into kerogen, which becomes oil as it warms up to 110 degrees Celsius. Natural gas then forms from oil at temperatures above 110 degrees
2018年11月15日 In the field of olive oil extraction, current scientific research has focused on improving quality, paying particular attention to optimizing the efficiency of extraction and reducing the duration of the process. Recently, studies have been conducted to improve the traditional malaxation process and obtain positive effects on both oil production and
