The aim of this contribution is to measure the effect of the pretreatment of lignocellulosic phytomass utilization for bioethanol production. The first step of bioethanol production from lignocellulosic phytomass is pretreatment of raw material. The next step is hydrolysis, and then the...

Sediment and nutrient exports were evaluated in a small agriculture-dominated watershed that drains into Rondeau Bay, on the northern shore of Lake Erie in Southwestern Ontario, Canada. The following hypothesis was tested: the quantity and quality of suspended sediment yields in agricultural...

Zirconium diboride is widely applied to high-temperature materials, but it is easily oxidized at high temperature. To increase the oxidation resistance of zirconium diboride at high temperature, the A1(OH)3–Y(OH)3 is coated on the ZrB2 surface to prepare A1(OH)3–Y(OH)3/ZrB2 composite...

The process of microwave irradiation (MWI) pretreatment on microcrystalline cellulose (MCC) with different sizes with/without NaOH was investigated on the variation of the ratio of degradated solid residue (RDS), particle size, crystallinity index (CrI), crystallite size (Sc) and specific...

Cellulosic ethanol made from cellulosic biomass is a promising alternative to petroleum-based transportation fuels. Enzymatic hydrolysis is a crucial step in cellulosic ethanol production. In order to better understand the mechanisms of enzymatic hydrolysis, relationships between cellulosic...

Two different sugar yield definitions (cellulose-based and biomass-based) were used in reported studies investigating the relationship between biomass particle size and enzymatic hydrolysis sugar yield. It is noticed that these reported relationships are not consistent if sugar yield is defined...

Steam gasification of a phenolic board in the presence of molten carbonate was studied as a means to recover useful metals effectively from electronic waste while also converting its plastic fraction into clean fuel gas. In the steam gasification of the phenolic board, the presence of carbonate...

Sand filters are beds of granular material placed in cylindrical metal containers. They are used as one approach for irrigation water filtration, mainly to remove organic and algae contaminants. The field effectiveness of these devices depends on their proper operation. The objectives of this...

Niobium powder was fabricated by metallothermic reduction process using K2NbF7 as the raw material, KCl and KF as the diluents and Na as the reducing agent. The apparatus for the experiment was designed and built specifically for the present study. Varying properties of niobium powder depending...

Carbonisation experiments on samples of sugar cane bagasse were conducted in a static fixed bed reactor to determine the effect of process variables such as temperature, heating rate, inert sweep gas flow rate and particle size on the yield and composition of solid product char. Experiments were...
