Biomass gasification: Still promising? A 30-year global overview

Abstract: Over the past decades biomass gasification has been regarded as a very promising technology, because of the large potential and the option of advanced applications. In this paper a 30-year overview is presented of the worldwide development of biomass gasification as part of the more general field of gasification, based on both literature and science and technology indicators. The first period of development until the mid-80s is characterized by large interest in coal gasification and domination by the USA. The second period relates more to biomass gasification. It starts in the mid-1990s and is dominated by Europe, although China and Japan are coming up strongly. The technology has been successful in a few niche markets, but largely remains confined to RD&D niches. High-end applications like IGCC and transport fuels have received major interest in research and development. However, biomass gasification is not yet mature enough to be widely applied in the market. It is still in a stage of variation and there has been no dominant design yet. In most markets it is unable to compete with other technologies. We do not expect a breakthrough on the short term, a gradual niche development seems much more likely.

Fatigue Properties of Highly Oriented Polypropylene Tapes and All-Polypropylene Composites:

Abstract: This paper describes the fatigue behaviour of newly developed all-polypropylene (all-PP) tapes and composites, with reference to the composite processing conditions, testing temperature and making a comparison with commercial alternatives. All-PP tapes are highly oriented and their failure behaviour follows that of other highly oriented polymers. All-PP woven composites fail ultimately due to PP tape failure. However, this failure mode is accompanied by delamination of fabrics in the woven structure. Consolidation pressure plays a decisive role in controlling the interlaminar properties and hence the delamination resistance and furthermore the fatigue limit of the composite. Comparison of all-PP woven composites with commercial alternatives based on glass and natural fibres reveals the excellent relative performance of all-PP composites under fatigue loads. Fatigue properties of all-PP composites are however sensitive to the testing temperature, and elevated temperatures can lead to a rapid reduction of the fatigue resistance of these all-polymer systems.
