Becoming a net importer of crude oil has encouraged China to develop new energy systems for heat and power generation. Increasing crude oil prices have increased the potential wide influence on China’s economic growth. This article explores the influence of domestic renewable energy policy regarding the China Energy Outlook for the years 2015–2035. Applying the national roadmap of renewable energy, three scenarios are constructed: wind energy, biomass energy, and solar energy. The advantages and disadvantages of these scenarios are studied and some suggestions are proposed to improve the economic aspects of renewable energy development.

This study aims to present an integrated process that can be used to produce biomedical and biological active components from the fruit shell of Camellia oleifera Abel. Through the Foss method, Aldehyde, acid compounds, acyl and alcohol compounds account for 22.7, 15.93, 0.24 and 61.13% of the extractives which were extracted from Camellia oleifera fruit shell by methanol solvents. Furfural, Pyrazole-4-carboxaldehyde, 1-methyl- and 5-Hydroxymethylfurfural account for 4.74, 1.22 and 58.78% of the extractives which were extracted from the fruit shell of Camellia oleifera Abel by ethanol solvents. Aldehyde, acid and amine compounds account for 5.01, 56.18 and 7.20% of the extractives which were extracted from the fruit shell of Camellia oleifera Abel by ethyl acetate solvents. The extractives of fresh flesh of bayberry were rich in rare drug, biomedical and biological activities.

The most important characteristics and limitations of solar energy were reviewed in this study. The analysis of different aspects indicated that the most important global challenges of solar energy development were climatic challenges, technical constraints, and unwillingness to make investments. After describing current conditions and predicting the future of solar energy, this study analyzed the policies formulated by developed countries to develop this from of energy. Accordingly, China has gotten ahead of other countries in this industry due to the technological production of solar panels and governmental supports. Finally, the economic estimation of solar energy was presented by dealing with the economic barriers to this form of energy in developed countries. According to the significant growth in the reduction of solar energy electricity production cost, this source of energy can be used as a major source in the future. It was then recommended to use a hybrid of solar energy with other sources such as wind to reduce the costs.

Sulfur particles, which could cause diseases, were the main powder of smog. And activated carbon had the very adsorption characteristics. Therefore, five sulfur particles were adsorbed by activated carbon and were analyzed by FT-IR. The optimal adsorption time were 120 min of Na2SO3, 120 min of Na2S2O8, 120 min of Na2SO4, 120 min of Fe2(SO4)3 and 120 min of S. FT-IR spectra showed that activated carbon had the eight characteristic absorption of S-S stretch, H2O stretch, O-H stretch, -C-H stretch, conjugated C 000000000000 000000000000 000000000000 111111111111 000000000000 111111111111 000000000000 000000000000 000000000000 O stretch or CC stretch, CH2 bend, C-O stretch and acetylenic C-H bend vibrations at 3850 cm-1, 3740 cm-1, 3430 cm-1, 2920 cm-1, 1630 cm-1, 1390 cm-1, 1110 cm-1 and 600 cm-1, respectively. For Na2SO3, the peaks at 2920 cm-1, 1630 cm-1, 1390 cm-1 and 1110 cm-1 achieved the maximum at 20 min. For Na2S2O8, the peaks at 3850 cm-1, 3740 cm-1 and 2920 cm-1 achieved the maximum at 60 min. The peaks at 1390 cm-1, 1110 cm-1 and 600 cm-1 achieved the maximum at 40 min. For Na2SO4, the peaks at 3430 cm-1, 2920 cm-1, 1630 cm-1, 1390 cm-1, 1110 cm-1 and 600 cm-1 achieved the maximum at 60 min. For Fe2(SO4)3, the peaks at 1390 cm-1, 1110 cm-1 and 600 cm-1 achieved the maximum at 20 min. For S, the peaks at 1630 cm-1, 1390 cm-1 and 600 cm-1 achieved the maximum at 120 min. It provided that activated carbon could remove sulfur particles from smog air to restrain many anaphylactic diseases.
