In this work, hydroxyapatite/silica nanopowders were granulated to fabricate plasma sprayable feedstocks. For this purpose, the wet powders obtained by heating a hydroxyapatite/silica slurry were stirred and sieved. To realize the feedstock application in the plasma spray process, powders were deposited on titanium substrate. The morphology of granulated feedstock and sprayed coating was ...

A manufacturer with feedstock-intensity flexibility can adapt to a rise in feedstock costs or fall in output prices, by shifting the mix of inputs to rely less on feedstock (by using less or lower quality feedstock) and more on production resources (by increasing processing time). In contrast to conventional wisdom that variability increases the value of flexibility, the value of feedstockinten...

The size of the U.S. bioindustry will, to a large degree, be determined by the quantity and quality of biomass available. As the starting material in the biomass-to-biofuels supply chain, a sufficient and secure supply of affordable feedstocks is a critical step in accomplishing the Program goals. The Feedstock platform therefore relates strongly to all other facets of the program portfolio; it...

Most of the fuel ethanol plants in Canada were built recently and either use corn or wheat as feedstock. It is important to determine what factors affect decisions about when and where to invest in building new ethanol plants and which feedstock is chosen as feedstock. In this paper we model the decision to invest in ethanol plants using a structural model of a dynamic game. We find that compet...

There is a strong societal need to evaluate and understand the sustainability of biofuels, especially because of the significant increases in production mandated by many countries, including the United States. Sustainability will be a strong factor in the regulatory environment and investments in biofuels. Biomass feedstock production is an important contributor to environmental, social, and ec...

in this research, the energy flow and production energy indices of canola cultivation in trakya province of turkey, golestan and mazandaran provinces of iran were compared. diesel fuel and chemical fertilizer inputs were the highest consumer of energy in the production of canola in these three regions. the results indicated that despite the higher energy use of machinery in trakya province of t...

Research barriers continue to exist in all phases of the emerging cellulosic ethanol biorefining industry. These barriers include the development of sustainable and abundant biomass feedstock, the assembly of viable assembly systems formatting the feedstock and moving it from the field (e.g., the forest) to the biorefinery, and improving conversion technologies. Each of these phases of cellulos...

The low bulk density and low flowability of lignocellulosic biomass feedstock have been regarded widely as major barriers for a sustainable and efficient supply system. Densification of biomass is a viable option to increase the bulk (and inherent energy) density and flowability of feedstock, leading to improved efficiency of the supply system. The energy consumption of feedstock densification ...

Local bioenergy will play a crucial role in national and regional sustainable energy strategies. Effective siting and feedstock procurement strategies are critical to the development and implementation of bioenergy systems. This paper aims to improve spatial decision-support in this domain by shifting focus from homogenous (forestry or agricultural) regions toward heterogeneous regions—i.e., ar...

Aqueous phase reforming (APR) of biomass derived feedstock producing hydrogen was reviewed. The APR process was discussed based on different feedstock categories such as sugars, polyols and ethanol. The mechanism of APR was analyzed referring to different structures of feedstock. The reaction pathways of APR were investigated. The usage of catalysts should be judged by feedstock on the requirem...
