Oxygen-Carrier-Aided Combustion (OCAC) is a promising technology for the combustion of solid heterogeneous fuels such as biomass and waste. However, frequently encountered problem with waste their high alkali contents, which can lead to build-up deposits on heat transfer surfaces, leading corrosion increased maintenance costs. The addition elementary S one options used in processes mitigate cor...

Biomass chemical looping gasification (BCLG) is a complex process for the conversion of biomass using an oxygen carrier, which influenced by various operating parameters. For better understanding this process, steam ilmenite as carrier numerically investigated in work multiphase particle-in-cell (MP-PIC) method, modified Euler–Lagrange approach. As first step, reduced reaction network spouted b...

The Chemical Looping with Oxygen Uncoupling (CLOU) process is a derivative technology of the Combustion (CLC) for combustion both renewable and non-renewable solid fuels. present work studies CO2 capture efficiency burning coal or biomass using single Cu-based oxygen carrier magnetic properties as an carrier. two different coals three biomasses was performed in 1.5 kWth CLOU continuously operat...

This study investigated carrier compensation induced by thermal annealing in sputtered ZnO:Al (Al₂O₃: 0.25, 0.5, 1.0, and 2.0 wt %) films. The films were post-annealed in a N₂ atmosphere at low (1 × 10-23 atm) and high (1 × 10-4 atm) oxygen partial pressures (PO2). In ZnO:Al films with low Al contents (i.e., 0.25 wt %), the carrier density (n) began to decrease at annealing temperatures (Ta) of...

INTRODUCTION Physical plasma is a promising new technology regarding its antimicrobial effects. This is especially accounting for treatment of bacterial infection of chronic wounds. Plasma can be generated with different carrier gases causing various biological effects. Screening of different carrier gases and plasma generation setups is therefore needed to find suitable compositions for highly...

The heart and those striated muscles that contract for long periods, having available almost limitless oxygen, operate in sustained steady states of low sarcoplasmic oxygen pressure that resist change in response to changing muscle work or oxygen supply. Most of the oxygen pressure drop from the erythrocyte to the mitochondrion occurs across the capillary wall. Within the sarcoplasm, myoglobin,...
