Municipal solid waste conversion to energy

In recent years it has been recognised by an increasing number of nations that there is considerable energy potential within MSW. As a result many countries have established R,D& D programmes to examine methods of exploiting this potential. The IEA's MSW Conversion Activity was set up in 1986 to provide an infrastructure for sharing information and co-ordinating work in this area internationally. This Activity was extended in 1989 and currently a total of 9 nations participate in it.

To cope with the wide scope of the area (encompassing both biological and thermal processing of MSW) the Activity was divided into three subgroups or Expert Working Groups (EWGs). Each of these dealt with a distinct area of expertise:

1. •Downstream effects of source separation and screening of MSW

2. •Sampling and analytical protocols

3. •Landfill gas

In addition to these groups a central secretariat based at Harwell (UK) has provided guidance, established and administered databases of contacts and produced a series of national reports.

This paper describes the achievements of the Activity and discusses work proposed for the future.

东海盆地西南部地质特征与油气分布探讨

本文根据近3×10~4km地震和13口探井及其它地球物理、地质等方面资料,综合分析认为:东海盆地西南部与盆地其它部分在发育演化、构造运动、沉积环境等方面差异甚大。 盆地西南部(杭州湾—冲绳岛断裂以南地区)发育演化经历了断陷—坳陷—隆起—铺盖四个阶段。始新世末期的隆起在研究区演化史上有15～20Ma的沉积间断、剥蚀。这段历程,盆地其它部分未曾经历。其次是区内始新世末期抬升运动,致使始新统及以下老地层受剥蚀,仅始新统最大剥蚀量达1000m,这是盆地内绝无仅有的。第三是第三纪以海相沉积环境为主,特别在始新世,为海侵高潮,海城宽阔达8000km~2,这时盆地东北部正接受陆相沉积。研究区中部(北东向)可能存在超压泥岩及多套生油岩系,应为有利生油气区。研究区可能是盆地最有油气远景地区之一。

加强石油天然气工业的立法，是社会主义市场经济发展与油气勘查开采实践的需要。针对现行油气管理法规在矿种管理体制，相邻采矿权人关系，油气采矿人主体资格，解决采矿权纠纷等未明事项，运用法学理论进行了剖析；阐述了加强油气立法工作的必要性和紧迫性；并有针对性地提立法建议，以期引探讨和有关部门重视。     

Ideal-gas thermodynamic properties for natural-gas applications

Calculating caloric properties from a thermal equation of state requires information such as isobaric heat capacities in the ideal-gas state as a function of temperature. In this work, values for the parameters of thec _p ⁰ correlation proposed by Aly and Lee were newly determined for 21 pure gases which are compounds of natural gas mixtures. The values of the parameters were adjusted to selectedc _p ⁰ data calculated from spectroscopic data for temperatures ranging from 10 to 1000 K. The data sources used are discussed and compared with literature data deduced from theoretic models and caloric measurements. The parameters presented will be applied in a current GERG project for evaluating equations of state (e.g., the AGA 8 equation) for their suitability for calculating caloric properties.
