The preparation of composite carrier by using diatomite and activated carbon for desulfurization in flue gas

In this study, the diatomite and activated carbon were selected as raw materials to prepare the composite carrier for desulfurization. The orthogonal experiments were performed to optimize the preparing conditions, and the influences of the mass ratio of activated carbon to diatomite, the content of acetic acid, calcination temperature and calcination time on desulfurization performance of composite carrier were investigated. The experimental results show that the desulfurization performance of composite carrier strongly depends on the preparing conditions, and the best preparing condition was shown as follow: the ratio of activated carbon to diatomite 2:3, acetic acid 3 ml/10 g composite carrier, calcination temperature 400 degrees C, calcination time 3 h.
