摘要
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。
Semi-synthetic cracking catalyst for oil refining (FCC), whosecrude materials are dominated by kaoline, has become a main catalyst inpetrochemistry at home and abroad. In China, the kaoline only from Suzhou issuitable resource for FCC and thus it is very shortage. Guizhou and its adjacentSouthern Sichuan is only a continuous source area of halloysite ores in the world,where there are over 300 halloysite occurrences and all are tubular 10 Ahalloysite. Halloysite ore formational processes would include leaching ofmeteoric water to kaoline mother rocks under exogenic conditions and dissolvingof ore-bearing solution to underlying carbonate bedrocks and the both hadoperated simultanrously since Neogene.In FCC, such indexes as internal and external specific surface areas, porevolume, pore size distribution, reserved porosity ration after calcining, activatingcatalytic index, transformation ratio of light oil and cracking ability of residual(heavy) oil are advantageous over those of standard soil─Sun B-1 that is used ascatalyst in China, due to particular mineral texture of halloysite.
