As one of the most developed provinces in China, Shandong has consumed large amount of energy and released a lot of CO2 during the economic development. Moreover, the power industry has consumed more than half of the energy and released the most CO2. In order to explorer the situation of carbon emissions in Shandong province, investigation and demonstration have been done based on the present power structure situation. The investigation and study result indicated that the low carbon development route and strategy in Shandong could be divided into two ways: making full use of the new clean energy and developing power generation technology with high efficient.

The effects of three kinds of red mud from alumina plant on limestone’s sulfation kinetics were investigated by thermogravimetric analysis method. Red mud can effectively improve the desulfurization performance of limestone in the whole temperature range. Red mud has little effect on the rate constant of the surface reaction (k), but it can significantly improve the effective diffusivity of reactant in the product layer (Ds). The enhancement of sulfation is more pronounced once the product layer has been formed and consequently the promoting effect becomes greater once the sulfation reaction becomes diffusion controlled.

The enhancement of alkaline industrial wastes on the desulfurization performance and utilization of limestone has already been found. In order to explore the reason of this phenomenon from the kinetic point of view, two typical alkaline wastes, carbide slag with a high calcium content and Bayer process red mud with more metal impurities, were adopted to research. Kinetic behavior of calcination reaction was calculated using the isoconversional method of Kissinger-Akahira-Sunose method (a differential method) and Flynn-Wall-Ozawa method (an integral method) at four different heating rates: 10, 20, 40 and 80 K•min-1. Values calculated by these two methods are very close, and the calculated result shows that calcination rate constant of modified limestone is obviously greater than that of original limestone, under the same calcination temperature, which means that alkaline wastes are advantageous to the thermal decomposition of limestone.
