世界燃料乙醇产业发展态势 总被引:1,自引:0,他引:1
文章分析了世界燃料乙醇的主要发展国家——美国、巴西、欧盟和我国的发展动态,认为该产业近年来受世界金融危机的影响发展步伐总体趋缓。美国和巴西,作为位居世界燃料乙醇行业前列的国家,其产量和消费量增速近年均明显变缓;欧盟各国燃料乙醇产业虽然快速发展,但总量不大,在生物燃料总的份额中所占比例很低;我国对燃料乙醇产业的发展较为积极,进行了一些试点和产业化示范,产量位居世界第三位。文章提出,我国在发展燃料乙醇产业方面应注重技术研发,突破产业化瓶颈,并充分考虑我国人多地少的基本国情,合理控制燃料乙醇产业的发展规模和产业化步伐。 相似文献

车用乙醇燃料的发展与对策分析 总被引:3,自引:0,他引:3
一、国外车用醇类燃料的发展状况乙醇俗称酒精,它以玉米、小麦、薯类、糖蜜植物等为原料,经发酵、蒸馏而制成。将乙醇进一步脱水再经过不同形式的变性处理后成为变性燃料乙醇。车用乙醇燃料是指把变性燃料乙醇和汽油或柴油按比例混配而成的车用燃料。乙醇燃料替代汽油或柴油用于汽车发动机,尾气排放量比用汽油和柴油都低,对环境更有利。随着公众环境意识的增强和经济发展对能源供给压力的加大,燃料乙醇产业在全球范围内得到广泛重视与发展。受“石油危机”的影响,许多国家为了能源安全和平衡外汇,都在积极寻找石油的代用品。乙醇大规模用作… 相似文献

Since the beginning of this century, revolutionary progress has been made in the understanding of resources and in the mining technologies of the oil and gas industry. Advances in petroleum engineering technology represented by horizontal wells and large-scale fracturing have promoted the scale development of low-grade and unconventional oil and gas resources. After the rapid growth of natural gas production in China for more than 10 consecutive years, the replacement of conventional natural gas resources has been weak and unconventional natural gas has become the major force for increasing production. Coal based SNG(synthetic natural gas) has also become a major competitor in the domestic market. The development of CTL(coal-toliquids) and SNG industries has brought coal resources into the oil and gas product market, expanding the concept of traditional oil and gas resources. The continuous improvement of petroleum engineering technology has promoted the development of deep underground coal gasification technology, which has given economic value to the huge amount of deep coal resources that are unable to be exploited by underground mining, and provides a tremendous resource guarantee for the sustainable development of the traditional oil and gas industry. A preliminary calculation shows that deep underground coal gasification has a competitive advantage in cost compared with high-cost, low-grade, unconventional gas and coal-based natural gas. Deep underground coal gasification is a typical cross-disciplinary and cross-sectoral sophisticated technology. Domestic oil and gas enterprises have dominant advantages in the engineering technology of this field. Further technical integration innovation and multi-industry joint research are needed to eventually realize the commercial application of this deep underground coal gasification technology. 相似文献

During the 1 lth Five-Year Plan period,China's ethylene industry witnessed rapid expansion in production scale,through reconstruction and extension as well as new construction.The capacity was increased to 14.169 million t/a in 2010 from 7.859 million t/a at the end of 2005,with the growth rate being 80.3%.So China became the second largest ethylene producers only after the United States.It is predicted that China's newly increased ethylene production will be 7.4 million t/a by 2015,and total ethylene production will reach 21.569 million t/a. 相似文献

变性乙醇是车用化石燃料的理想替代品之一。我国汽车使用乙醇汽油始于2000年,由于其具有节油、环保和促进农业发展三大优势,被我国决策部门列为具有战略地位的重点项目。作为一个新兴的发展方向.乙醇汽油的发展还存在很多问题,其中最为重要的是它与汽油、天然气等目前的主流车用能源相比,具有明显的经济弱势,尤其是生产成本决定了乙醇汽油在价格上缺乏竞争力。章对影响乙醇汽油生产的若干经济问题及技术因素作了探讨,指出了乙醇汽油工业健康发展所需的政策环境,说明了要获得可以接受的乙醇汽油价格需要政府、生产企业及消费的共同努力。 相似文献
