Methanol steam reforming plays a pivotal role to produce hydrogen for fuel cell systems in a low temperature range. To accomplish higher methanol conversion and lower CO production, the reaction was catalyzed by CuZnFe mixed oxides. Various ratios of Fe and Cu/Zn were coprecipitated in differential method to optimize the CuZnFe structure. The sample containing 45Cu50Zn5Fe (Wt. %) revealed its m...

In industrial scale of Gas to Liquid (GTL) process in Fischer-Tropsch (FT) synthesis, a part of reactor outlet gases such as CO2 and CH4 as side reaction products, is usually recycled. In this study, the influence of CO2 and CH4 on the performance and selectivity of Co-Ru/Al2O3 catalyst is investigated by injection of these gases (0-20 vol. % of feed) to the feed stream. The effect of temperatu...

Laboratory facilities use many varieties of contact bedding, including wood chips, paper products, and corncob, each with its own advantages and disadvantages. Corncob bedding, for example, is often used because of its high absorbency, ability to minimize detectable ammonia, and low cost. However, observations that mice eat the corncob lead to concerns that its use can interfere with dietary st...

this study was carried out to evaluate the impacts of organic (sel-plex® selenium yeast) and inorganic (sodium selenite) selenium and vitamin e (d1-α-tocopheryl acetate) on performance and carcass characteristics in broiler chickens. the effect of two types of house temperature and six treatments of feed additives were investigated in a 2×6 factorial experiment at 56 days period with 960 commer...

This research aimed to determine the effect of dietary treatments and age on fattening process in cattle. Thirty-six Ongole crossbred cattles were allotted into two different three groups, with six replications for 24 weeks period, 4 preliminary followed by 20 data collection at Beef Cattle Research Station (BCRS). The experimental design was completely randomized a 2 x 3 factorial. cattle plac...

an experiment with 240 one-day-old lohman male broilers was conducted to investigate the effects of different levels of palm kernel meal supplemented diet with/without enzyme on performance and lactic acid bacteria population of ceca. birds were distributed in 20 experimental units and data were analyzed in a complete randomized design with 2x2 arrangement plus a control diet.the levels of palm...

Objective: The effect of xylanase and fructooligosaccharides on broiler chickens body weight, feed conversion (kg feed/kg weight), caecal volatile fatty acids (VFA) concentration and glycolytic enzymes activity was investigated. Methods: Six hundred birds were divided into three groups and for 35 days were fed basal diet (control) and diets contained 0.1% xylanase and 2% fructooligosaccharides ...

Abstract Purpose Objective of this study is the valorisation mass rearing waste fruit flies from sterile insect technique facilities by black soldier into high quality and quantity products as a sustainable utilisation concept. Methods Different ratios medfly in hen feed were used for solder fly (BSF) larvae. The growth rate survival determined. Moreover, gains determined bioconversion rates as...

One hundred grams fat, based on blends of beef tallow and soya oil (0:100, 20:80, 40:60, 60:40, 80:20 and 100:0) which corresponded to dietary ratios of unsaturated to saturated fatty acids (U:S ratio) of 5.47, 3.23, 2.11, 1.45, 1.00 and 0.69, respectively, was incorporated into a rye-based broiler diet (610 g kgÿ1). All diets were tested without or with supplementation of a xylanase-containing...
