Traditional oil/water separation materials were prepared with partial or all nonrenewable raw materials, which would not only increase resource consumption but also cause new environmental pollution after being abandoned. In this work, a superhydrophobic and superoleophilic oil/water separation all-natural material was prepared using a simple and fast emulsion immersing method. The raw materials used including natural sponges and natural vegetable waxes, all of which are renewable. The as-prepared all-natural material can not only absorb various oils from water with high oil absorption capacity, fast oil absorption rate, and good recyclability but also achieve reuse of the absorbed oil by squeezing. In addition, the as-prepared all-natural material exhibits strong stability against cyclic compression, excellent resistance to corrosive aqueous solutions contacting, and organic solvents immersing. Furthermore, the surface wax coating can be easily recycled. This work provides a new method to prepare oil/water separation materials by using all-natural and renewable raw materials.

“…In recent years, a lot of research has carried out on the application of pyrolysis biomass char in blast furnace injection . Yousaf et al studied the combustion characteristics of biomass char obtained from the pyrolysis of peanut shell and wheat stalk at 300, 500, and 700 °C and found that when the mass ratio of biomass char was 50%, the blends mixed with pulverized coal had the highest combustion efficiency.…”

Basic property analysis is the most comprehensive evaluation of metallurgical characteristics of blast furnace injection fuel. In this study, the basic properties of 16 types of pyrolysis biomass char samples were comprehensively investigated; the results showed that components harmful to a blast furnace, such as the ash content and alkali metal content of Jiangsu Suzhou woodblock char (B3), Jiangsu Changzhou branch char (B8), Jiangsu Zhangjiagang bamboo char (B10), and Jiangsu Zhangjiagang coconut shell char (B12) in all of the biomass char samples, are lower and close to the level of blast furnace injection bituminous coal. The grindability, particle size distribution, and safety all met the requirements of the blast furnace. Among them, the ash melting characteristic temperature of B3, B8, Jiangsu Zhangjiagang rice husk char (B11), and Shanghai soil remediation agent (B16) was greater than 1250 °C, indicating that they are not easy to block the blast furnace raceway and spray guns. Most of the biomass char samples had good combustibility, and the burnout temperature was less than 700 °C. A self-developed blast furnace injection combustion simulation experimental device was used to simulate the combustion behavior of biomass char in the blast furnace raceway tuyere, and the burnout rates of 16 biomass chars were measured. The results showed that that the burnout rate is related to both the volatiles and fixed carbon and the influence of volatiles on the burnout rate is greater than that of fixed carbon. The burnout rates of B3 and B8 were 77.12 and 67.03%, respectively. Above all, B3 and B8 showed good properties, but the burnout rate of B3 was higher, so B3 had the feasibility of applying to blast furnace injection, which indicates that woodblock char has the potential to be used as blast furnace injection fuel.

The decolorization and quality improvement of the high melting point Fischer-Tropsch wax were carried out by the method of adsorption refining, and the activated clay was selected as adsorbent. The effects of adsorption decolorization temperature on the wax products were evaluated by testing the saybolt color number and whiteness value of the waxes. Meanwhile, the influence of adsorption decolorization temperature on the composition of waxes was investigated by gas chromatography (GC), inductively coupled plasma (ICP), thermogravimetry/differential thermogravimetry (TG/DTG), differential scanning calorimetry (DSC), thermogravimetric mass spectrometry (TG-MS), Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR), scanning electron microscopy (SEM), and X-ray fluorescence (XRF) characterizations of waxes and adsorbents activated clay before and after use. The results showed that the best adsorption decolorization temperature is 120 C, and the corresponding saybolt color number of decolorization waxes is +16. The reasons for the poor chromaticity of high melting point wax are not only the inorganic components mainly composed of residual ultrafine catalyst particles but also the organic components of unsaturated carbon-carbon double bonds and heteroatomic compounds containing oxygen, nitrogen, and sulfur. The oxidative deterioration of the unsaturated carbon-carbon double bond and hydrocarbons with low bond energy in waxes, as well as the oxidation of hydrocarbons containing oxygen and nitrogen heteroatoms, may be the main reasons for the yellowing of the wax products in the process of decolorization.
