Char is a low-value byproduct of biomass gasification and pyrolysis with many potential applications, such as soil amendment the synthesis activated carbon carbon-based catalysts. Considering these high-value char could provide economic benefits to biorefinery utilizing or technologies. However, properties depend heavily on feedstock, gasifier design operating conditions. This paper reports effects type (switchgrass, sorghum straw red cedar) equivalence ratio (0.20, 0.25 0.28), i.e., air...

Using the Nationwide Personal Transportation Study surveys of 1977 and 1983-84, this article demonstrates that there is no discernible relationship between city size class trip lengths, times, speeds, commuting speeds did not decline 1983. The most convincing explanation why congestion become more severe continued spatial decentralization both firms households, which permitted travel economies, especially for suburban residents in larger cities. competitiveness large metropolitan areas...

Biomass gasification is a proven technology; however, one of the major obstacles in using product syngas for electric power generation and biofuels removal tar. The purpose this research was to develop evaluate effectiveness tar methods by cooling wood shavings as filtering media. performance filter equipped with an oil bubbler heat exchanger systems tested tar-laden generated from 20-kW downdraft gasifier. reduction efficiencies filter, exchanger, were 10%, 61%, 97%, respectively.
