Method for producing fuel gas and co-producing cement from limestone
The invention discloses a method for producing fuel gas and co-producing cement from limestone, which comprises the following steps: adding a catalyst into limestone powder, uniformly mixing, adding into a preheating decomposition furnace, and reducing and decomposing to obtain fuel gas and lime containing the catalyst; performing magnetic separation on the lime containing the catalyst to obtain the catalyst and the lime; lime, a mineralizer and a silicon source are mixed to obtain a cement raw material, and the cement raw material is calcined to obtain the low-carbon Portland cement. Compared with the existing technical scheme, the method is simple to operate and low in cost, and resource utilization of carbon is realized.
本专利公开了一种石灰石生产燃气联产水泥的方法，在石灰石粉中加入催化剂混合均匀后，加入预热分解炉还原分解后得到燃气、含催化剂的石灰；含催化剂的石灰通过磁选分离，得到催化剂和石灰；将石灰、矿化剂与硅源配料后得到水泥生料，水泥生料煅烧后，得到低碳硅酸盐水泥。同已有技术方案相比，本方法操作简单，成本低，实现了碳的资源化利用。
