Abstract: The present application provides a treatment method and device for a waste plastic. A first aspect of the present application provides a treatment method for a waste plastic, including: firstly subjecting the waste plastic to a first pre-treatment to remove impurity and grease on a surface of the waste plastic, then subjecting the waste plastics to a second pre-treatment to convert a solid waste plastic into one in flow state; and finally, subjecting the waste plastic in flow state to a first cracking treatment and a second cracking treatment in sequence. Through the method provided in the present application, while cracking the waste plastic, chlorine element in the waste plastic may be removed by a multi-stage adsorption, which reduces chlorine content in the cracked oil, reduces pressure and burden in subsequent refining, and meets the limitation of the chlorine content in cracked products in downstream processes.

Abstract: Proposed are a method of preparing a cesium adsorbent and a cesium adsorbent prepared thereby. The method includes (a) preparing a powder mixture of coal mine drainage sludge (CMDS) powder, sodium hydroxide (NaOH) powder, and sulfur (S) powder and (b) heat-treating the powder mixture to prepare a cesium adsorbent. The cesium adsorbent increases the active ion exchange of Na and Cs and the bonding of S—Cs when adsorbing cesium ions, resulting in an average of 5 times higher Cs removal efficiency and adsorption capacity under various conditions compared to CMDS since CMDS relies on cesium adsorption by simple physical and electrostatic attraction. Moreover, the cesium adsorbent is eco-friendly and has excellent economic efficiency by utilizing waste CMDS.

Abstract: Described herein relates to an optimum, low maintenance and low-cost filtration media which may be implemented near a source water location as a pretreatment to remove tannic acid and/or humic acid (color) from dissolved natural organic matter (NOM) (i.e., tannic acid, humic acid) to impede the prompt production of disinfection by-products collectively termed trihalomethanes in drinking water treatment processes. In an embodiment, the filtration media may comprise a composition having a ratio of at least 83% sand, at most 5% clay, at most 6% ZVI and at most 6% perlite by percent volume.

Abstract: The present invention is in relation to a process for preparing calcium phosphate-based sulfated adsorbents that capture mercury in gas streams, comprised of the steps of synthesis of the precursors, incorporation of a transition metal, and sulfation of the material. These adsorbents present high efficiency both for removal of low concentrations of mercury, such as in natural gas, and for stabilization of this pollutant. The adsorbents obtained in the invention may be used in the Mercury Removal Units (MRUs) present in natural gas processing plants, which mercury removal units may be located either upstream or downstream of the dehydration and H2S removal units, due to the adsorbents obtained showing resistance to H2S poisoning, and maintaining their performance in the presence of water.

Abstract: A nitric oxide generator generates nitric oxide from a mixture of nitrogen and oxygen such as air treated by a pulsating electrical discharge. The desired concentration of nitric oxide is obtained by controlling at least one of a frequency of the pulsating electrical discharge and duration of each electrical discharge pulse.
