以高岭土为主料的炼油裂化催化半合成剂（ＦＣＣ剂），已成为中外石化工业的主体催化剂，我国仅有苏州高岭土为适用资源，缺口大。贵州及川南地区为世界上埃洛石的唯一连片产区，已有产地近３００处，全区均为管状１０Ａ埃洛石。成矿模式归结为：新第三纪以来，高岭石母岩在表生条件下，遭受淋滤作用和合矿液对下伏碳酸盐基岩的溶蚀，两种作用同步进行的“埋藏溶蚀成矿作用”。在ＦＣＣ剂中，埃洛石的内外比表面积，孔容及煅烧保留率、孔径分布、微活指数、轻油转化率及渣（重）油裂解力等指标，均优于我国催化剂标准用土─—苏机Ｂ─１，这些优异的炼油催化特性，均源于埃洛石的独特矿物结构。
Kaolinite-based refining and cracking catalytic semi-synthetic agent (FCC agent), has become the main catalyst for Sino-foreign petrochemical industry, only our country kaolin as a suitable resource, a large gap. Guizhou and southern Sichuan is the only contiguous producing area in the world, which has nearly 300 producing places. The whole area is tubular 10A halloysite. The metallogenic model is summarized as follows: Since the Neogene, kaolinite rock under the surface conditions, subjected to leaching and dissolution of the underlying carbonate rock carbonate dissolution of the two simultaneous simultaneous “burial corrosion Mineralization. ” In the FCC agent, the specific surface area, pore volume and calcination retention, pore size distribution, micro-living index, light oil conversion and slag (cracker oil) cracking strength of halloysite are all better than those of China’s catalyst standard- - Soy machine B ─ 1, these excellent refining catalytic properties, are derived from the unique mineral structure of halloysite.
