The major disadvantage of non-adaptive control systems is that these control systems cannot cope with fluctuation in the parameters of the process. One solution to this problem is to use high levels of feedback gain to ...

Lignocellulosic biomass has a great potential for biofuel and fine chemical productions. This study focused on the effective conversion of the lignocellulosic biomasses, particularly sugarcane bagasse to the most valuable ...

Cement industries are one of the major energy-intensive industries and heavy polluting process. To reduce the energy cost and environmental impact, cement producers are currently using alternative fuels. This study ...

Fossil fuels which are recognised as common sources of energy are continuously decreasing in quantity due to increasing demand, Moreover, the increase in atmospheric carbondioxide from chemical industries like cement ...

This work was done with the aim of producing biodiesel from vernonia galamensis oil by using ethanol with alkali catalyst, sodium hydroxide. Additionally it was investigated the effects of catalyst amount from 0.25 %( w/w) ...

The objective of this study was production of bioethanol from Barley spent grain by using two-stage diluted acid hydrolysis. The production process was carried out in four main stage such as pretreatment, hydrolysis (first ...

Waste brewery yeast has been used for biosorption of lead and nickel. The dried, ground and protonated yeast has been contacted with Lead (II) and Nickel (II) solutions so as to investigate impact of PH, Contact time, ...

Since the beginning of the twenty centuries molasses have been one of the major leading raw materials for yeast production. However molasses contains substances that inhibit the micro-organisms’ growth and can lead to ...

The main objective of the research was to prepare Fe iv 3+ -modified bentonite clay to be used as an adsorbent by optimizing the iron three loading through batch wise variation of agitation time, adsorbent dose, ...

Interest in biomass as a renewable energy source in Ethiopia has increased recently in response to a need to reduce greenhouse gas (GHG) emissions and to attain a green economy on 2025. The main objective of this study was ...
