Sustainable Chemical Technologies in Production of Clean Fuels from Fossil Fuels

Some aspects of the present and the possible future role of sustainable chemical technologies in the production of clean liquid and gaseous fuels from fossil fuels are discussed. The state‐of‐the‐art and the vision of possible sources and alternative routes which may lead to clean fuels from fossil fuels due to the progress in crude oil, natural gas and coal processing are briefly presented. The possible future role of the Fischer‐Tropsch synthesis, methanol synthesis, dimethylether synthesis, and a group of methanol transformation processes is also discussed.     

Electrochemical Ozone Production as an Environmentally Friendly Technology for Water Treatment

Perspectives, advances and environmental aspects concerning electrochemical ozone production applied to water purification are presented and discussed in relation to the conventional corona process (silent electric discharge). Ozone generated using a laboratory‐made electrochemical reactor was applied for the discoloration/degradation of dyes used in the Brazilian textile industry and for degradation of endocrine disruptors. A constant ozone load of 0.35 ± 0.02 g/h was used throughout. The study, concerning color removal from dye solutions, revealed that total discoloration is rapidly achieved. The degradation rate of the textile dyes evaluated by TOC is little affected by the dye composition and considerably influenced by the pH and ozonation time. Analysis of the COD/TOC‐ratio indicates that ozonation increases oxidation feasibility of the organic matter (dye by‐products) when compared to the original compounds. Ozonation of mixed aqueous solutions containing different endocrine disruptors revealed these compounds are totally degraded with a very high removal rate.     

无人机在地理国情应急监测中的应用探讨

近年来突发自然灾害等地理国情紧急事件频发,以传统的卫星遥感数据为数据源的地理国情监测手段无法有效的对紧急事件做出快速响应。无人机技术相对于其他遥感技术可以提供更高的实时性和准确性。无人机技术的飞跃,带动了地理国情监测技术的迅猛发展,且已经成为地理国情应急监测的核心手段之一。本文阐述了国内无人机遥感技术的发展现状,就无人机在地理国情应急监测中的应用进行探讨,试图通过实际应用找到其对地理国情应急监测的优势与技术问题,提升国情应急监测的技术水平,更好地服务于社会,促进防灾与减灾等应急技术的发展与完善。
