How do you create references for journal articles in APA format? If you need to write a psychology paper, then you are going to probably need to reference a number of different journal articles. Such articles summarize the results of studies and experiments conducted by researchers on an enormous range of topics.
The problem that second generation biofuel processes are addressing is to extract useful feedstocks from this woody or fibrous biomass, where the useful sugars are locked in by lignin, hemicellulose and cellulose. All plants contain lignin, hemicellulose and cellulose.
In additon. biofuels may be marketed as good, renewable, sustainable or next generation, partly for promotional purposes. So achieving a widely accepted definition of advanced and/or sustainable biofuels is a challenge. Often the term is applied to biofuels produced from lignocellulosic (LC) or cellulosic biomass.io-oil can be used as a heating fuel or can be further converted to advanced biofuels. Torrefaction (heating at 200-300 Â°C in the absence of oxygen, at atmopsheric pressure) converts biomass to bio-coal, which can be more easily used for power generation than untreated biomass.
