There has been an increase in the demand for bio-ethanol from different countries‚ including the Philippines in response to the wide implementation of environment protection laws. Bio-ethanol is ethanol derived from biomass has provided a sustainable source of energy fuel for transportation without increasing environmental hazard( ganguly‚ Chattejee‚ Dey‚2011). Eichhornia

resources like vegetable oil and animal fats. Sweet Potatoes (Ipomea Batatas) are being engineered by North Carolina State University. Scientist are source of ethanol to help the U.S. in their need of fuel. This is the reasons why the researchers decided to make biodiesel out of sweet potato (ipomea batatas) peel to test its feasibility in producing ethanol. ii General problem 1. How much sweet potato peel is needed to produced certain amount of biodiesel 2. Does the biodiesel

Pathogenesis. Basically‚ ALI is an acute lung inflammation that causes disruption of the pulmonary alveolar- capillary barriers (alveolar epithelium‚ interstitium‚ and microvascular endothelium)‚ which occurs in three phases; acute or exudative phase‚ resolution phase and fibrotic phase [8‚9]. 1. Acute or exudative phase (<72h)‚ which characterized by a disruption of the alveolar capillary membrane leading to leakage of protein rich fluid into the interstitium and alveolar space‚ and extended

concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change is decreasing. Discussion: The purpose of this lab was to observe and analyze various factors that affect the process of diffusion and osmosis. We observed that the permeability of the dialysis tubes‚ which is our permeable

mixture of ethanol and 1-butanol. in theory the fractional distillation should be more efficient because of the steel sponge. The sponge acted as surface area for gas to condense on. This prevented some of the 1-butanol from condensing into the vial during fraction A because it would condense onto the sponge and drip back down into the flask. The boiling point of 1-butanol is higher than the boiling point of ethanol‚ so the cooler surface of the sponge helped condense 1-butanol‚ but the ethanol still

or to provide heat to industries and homes. BIOFUELS "Biofuels" typically refer to fluid transportation fuels like ethanol‚ biogas and biodiesel that are made from biomass materials – but can include prepared solid biomass fuels. These fuels are: Often blended with the petroleum fuels - gasoline and diesel fuel‚ but they can also be used on their own. o Using ethanol or biodiesel means we don’t burn quite as much fossil fuel. Often more expensive than the fossil fuels that they
