干酪根广泛分散于沉积物的矿物基质中,含量少,分离困难。对于干酪根的提取,现阶段广泛采用化学和物理相结合的方法进行分离提取。分离过程大致分为两个阶段,即酸处理阶段和分离难溶矿物(主要为黄铁矿)阶段。酸处理是指用盐酸和氢氟酸反复处理除去碳酸盐和硅酸盐。酸处理后获得的残余物中,除干酪根 Kerogens are widely dispersed in the mineral matrix of sediments, with low content and difficult separation. For kerogen extraction, widely used at this stage a combination of chemical and physical separation methods. The separation process is broadly divided into two stages, the acid treatment stage and the separation of the refractory minerals (mainly pyrite). Acid treatment refers to repeated treatment with hydrochloric acid and hydrofluoric acid to remove carbonates and silicates. In the residue obtained after acid treatment, except for kerogen
