This study presents a detailed kinetic mechanism conducted by CHEMKIN for the homogeneous decomposition of SO3–H2O vapor in the sulfur–iodine cycle. The kinetic mechanism involving 27 reactions and 11 species was validated by experimental results. The effects of temperature, SO3/H2O ratio,...

To enhance energy production efficiency (EPE) from microalgae Chlorella pyrenoidosa (CP), cassava starch (CS) was mixed with CP to optimise the carbon/nitrogen (C/N) ratio and facilitate efficient dark hydrogen fermentation, followed by photo hydrogen fermentation and methanogenesis. Steam...

A novel thermochemical cycle, which uses alternative energy sources (such as solar, geothermal, and safe nuclear) to dissociate CO2 and H2O, is proposed. The cycle can effectively reduce CO2 emission from the combustion of fossil fuels. The products of the cycle include carbon monoxide, hydrogen...

A micro Newcomen engine is proposed. To overcome the problems of friction and leakage of the micro mechanical parts during engine's operation, we use a flexible ripple tube to integrate piston and cylinder into one monolithic part. Heptane is used as the working fluid, and it works in the...

In order to promote the desulfurization efficiency of calcium-based sorbents during coal combustion in traveling grate boilers, the influences on sulfur removal of the thermal conditions and the sorbents were discussed in this paper. It was found that the SO2 concentration first rises, then...

16s rRNA gene sequence analysis is applied in the semi-continuous fermentation of Chlorella pyrenoidosa to monitor changes in the microbial community of HPB (hydrogen-producing bacteria). The microbial community of HPB on the 4th day is mainly composed of one genus (Clostridium) including one...

A micro steam engine is developed based on Newcomen steam engine. In the micro engine, a flexible ripple tube takes the place of piston and cylinder, to overcome the serious problems of friction and leakage in micro scale. We use two-phase octane as working fluid of the micro engine, because...
