In order to use Moroccan beet pulp and sugarcane bagasse for the production of bioethanol, we conducted in present work a comparative analysis of different methods published in the literature and those currently employed in the industry for the production of bioethanol. Based on technical and economic criteria the chemical process with dilute sulfuric acid was chosen for the first and the second step...
The straw ethanol residue, a complex material, mainly consists of lignin and its derivatives. Lignin is a three-dimensional phenolic polymer and can be renewable and biodegradable, which has received increasing attention from research and utilization. The focus of this paper is to show the effects of straw ethanol residue on SBS waterproofing membrane properties. The results indicated that physical...
An experiment was conducted under hydroponic culture conditions to determine effects of nitrogen (N), phosphorus (P) and sulfur (S) deficiency on Tagetes erecta L. growth, cadmium (Cd) accumulation and chemical forms. Seedlings of similar age and size were pre-cultured in either N-, P-, or S-deficient nutrition solution for 12 days before exposure to 0.1 mg Cd L-1 (nonphytotoxic). The control group...
The yield and properties of bio-oil are influenced by the species of spray medium used in the biomass fast pyrolysis. In this study, the GC-MS analysis of the whole bio-oil and of the mixture with isoparaffin and ethanol respectively gave information about the influence of spray medium on bio-oil composition. It is found that isoparaffin, compared with ethanol, has a slighter impact on the bio-oil...
