Vol. 40, nr 1

The effect of addition of NaOH on the pyrolysis of rice straw and properties of its product were investigated. The pyrolysis was examined by means of the thermogravimetric (TG) analysis, and the pyrolysis product was characterized by the elemental analysis, GC and GC-MS. The result showed that addition of NaOH can significantly change TG and DTG peak of the pyrolysis of rice straw. As a result of the catalysis, significant difference in the properties of pyrolysis products was also observed. The addition of the catalyst promoted the increase of the hydrogen content of the gaseous product (from 1.6% to 53.37%), as well as that of the H/C and O/C ratios of solid residue. GC-MS analysis indicated that the liquid product was mainly made up of ketones, phenols and furfural, and NaOH addition did not change the main constitute of the liquid product, but changed their relative content.

Low Carbon Development of China’s Yangtze River Delta Region

Shan S., Bi X.

Problemy Ekorozwoju

2012

Vol. 7, nr 2

33-41

Low carbon development is a development pattern to enable social and economic progress along the path of sustainable development. This paper analyzes the low carbon development situation and trend in the China’s Yangtze River Delta region, one of the most important industrial and economic centers of China. The results indicate low carbon development in this region continues to move forward. However, many barriers, such as unbalanced energy consumption structure and limited research and development capability still exist. Some solutions to overcoming the barriers are proposed in the paper, covering policy, strategic, technological, educa-tional measures.

Gospodarka niskowęglowa sprzyja zarówno rozwojowi społecznemu, jak ekonomicznemu i jest zgodna z kon-cepcją rozwoju zrównoważonego. Ten artykuł analizuje uwarunkowania wprowadzania gospodarki niskowę-glowej w delcie rzeki Jangcy w Chinach, będącej jednym z najważniejszych przemysłowych i ekonomicznych obszarów w tym kraju. Otrzymane rezultaty wskazują na pozytywny rozwój gospodarki niskowęglowej na tym obszarze. Jednakże nadal występuje wiele barier, takich jak niezrównoważona struktura konsumpcja energii i ograniczone możliwości badawcze i rozwojowe. W artykule zawarto propozycje pokonania tych barier, uwzględniające wskaźniki polityczne, strategiczne, techniczne i edukacyjne,
