Abstract: The aim of this paper is to increase the level of hydrogen produced in the refinery from heavy treated Naphtha of Nigerian crude oil during catalytic reforming process. An existing continuous catalyst regeneration catalytic reforming process plant with four beds reactor was simulated using Aspen Hysys while treated heavy Napthene from Bonga Crude and Bonny Crude were used as feed for the process. The temperature of reactors for the process was varied between 430 – 540°C and the outlet concentrations of hydrogen (Vol.%) produced was recorded. It was observed that an increase in temperature lead to an increase in the concentration of hydrogen produced as the volume of hydrogen at 430°C was 23.46% volume while at 540°C it was 51.38% volume showing a significant increase in the aromatic yield level. The results also showed that the naphthene content of feed affects the volume of hydrogen produced which made Bonga crude a better source for hydrogen when compared with Bonny crude.

Abstract: Cheka is the most commonly used traditional food and drink for people who live around Konso and Derashe special woredas. The characterization of carbohydrate, protein and alcohol with estimation of protein and carbohydrate in cheka was done. The result obtained for all tests of alcohol, carbohydrate and proteins is positive result confirming their prescience in cheka. Most of cheka users have a body mass index (BMI) in the normal range which shows the positive impact of cheka, on human health.

Abstract: The hemicellulose from sugarcane bagasse was extracted sequentially with steam treatment followed by alkali and were characterized by chemical methods, SEC-MALLS, FT-IR and 13C NMR. The hemicellulose from steam pre-treatment was found to contain gluco-arabinoxylans while alkaline peroxide extraction yielded predominately linear arabinoxylans with varying amount of lignin. These arabinoxylans with high lignin content were tested for barrier properties on cardboards, to be used as food packaging materials. Due to lignin content, these hemicelluloses were found to increase the water barrier properties of the cardboard.
