Biomass pyrolysis is an advanced process which leads to obtaining products as chars, primary tars and gases. Depending on conditions reactor construction, the could be divided into three categories: slow, intermediate fast. This work concerns experimental analysis of biomass residues in a fixed bed reactor. As raw materials, pine bark wheat straw were selected. Experiments carried out at temper...

Greenhouse gas (GHG) emissions need to be reduced limit global warming. Plastic production requires carbon raw materials and energy that are associated today with predominantly fossil GHG emissions. Worldwide, the plastic demand is increasing annually by 4%. Recycling technologies can help save or reduce emissions, but they require comparative assessment. Thus, we assess mechanical recycling, c...

This study aimed to experimentally investigate the effects of dry flue gas on biomass torrefaction. In this work, an oil palm frond (OPF) was torrefied in a laboratory-scale horizontal torrefaction reactor at temperatures 240, 260, and 280 °C, with residence time 20 40 min, using variable compositions (N2/CO2/O2: 76/16/8, 80/14/6, 74/12/4). addition, experiments conventional were conducted for ...

in this study, green pepper was dried by a laboratory scale microwave-convective dryer. the effects of microwave power on drying rate, effective moisture diffusivity, and energy consumption of green pepper were studied at four different microwave powers of 180, 360, 540, and 720w. the drying data were fitted to the four thin-layer drying models. the moisture reduction of the green pepper sample...

This study was conducted to determine the annual energy use and related greenhouse gas (GHG) emissions of individual deep well irrigation enterprise. That at farm belonging one farmer with volunteer preforming farming activities in Konya-Meram-Çarıklar location for growing season 2021. In that regard, using alfalfa dry bean production, total production inputs their amounts as crop yields were d...

Studies were conducted to evaluate effects of weaning and subsequent heifer development treatments within two herds located in the Northern Great Plains, USA. Heifer calves from predominantly Angus Hereford dams were stratified within dam age and calving date (Fort Keogh Livestock and Range Research Laboratory (LARRL), Miles City, MT, USA; n1⁄4328) and randomly assigned within study and strata ...

Two experiments were conducted to evaluate the effects of chemical composition of wheat shorts and red dog on energy and amino acid digestibility in growing pigs and to establish prediction models to estimate their digestible (DE) and metabolizable (ME) energy content and as well as their standardized ileal digestible (SID) amino acid content. For Exp. 1, sixteen diets were fed to thirty-two gr...

INTRODUCTION Rabbits' eyes were exposed to vitreous humor liquefaction with Q - switched (sometimes called " giant pulses") Neodymium-Doped Yttrium Aluminium Garnet (Nd:YAG) laser using two different energy protocols (5 mJ X 100 pulse and 10 mJ X 50 pulse)with and without vitamin C administration. The histological changes in the retina were investigated to evaluate the protective role of vitami...
