    Abstract: 본발명은삼염화실란(trichlorosilane, 이하, TCS)의제조방법에관한것으로, 더욱상세하게는전자급혹은태양전지급실리콘(silicon) 생산을위해사염화실란(STC)으로삼염화실란(TCS)을제조하는공정에관한것이다. 본발명의실시예에따라사염화실란(STC)으로부터삼염화실란(TCS)을제조하는공정은, 트리클베드반응기(trickle bed reactor)에촉매를충진하는단계; 상기반응기로액상의사염화실란과기상의수소를공급하는단계; 상기반응기내 촉매상에서상기액상사염화실란과기상의수소에대하여하기반응식 1의반응이수행되는단계; 및상기반응을통해생성된기상의삼염화실란과염화수소생성물을분리하는단계를포함하며, 본발명에따르면 300℃이하반응조건에서도사염화실란의전환율을 40 % 이상으로얻을수 있고, 고순도의삼염화실란을연속적으로공정의중단없이얻을수 있는이점이있으며, 액상의미 반응사염화실란과기상의삼염화실란및 염화수소의분리가용이해져서반응속도가증가하고종전의기술과비교하여분리탑설치운전에따른분리비용이감소하는장점이있다: SiCl(l) + H(g) → SiHCl(g) + HCl(g).

    Abstract: A method of manufacturing light olefin from hydrocarbon is provided to manufacture light olefin with high selectivity and high purity from hydrocarbon material by maintaining high decomposition activity at low temperature. The method of manufacturing light olefin from hydrocarbon includes the steps of: (a) supplying hydrocarbon as a supply material; (b) transferring the supply material to inside of at least fixed bed or a fluidized bed, and reacting it under the presence of a catalyst; and (c) isolating and collecting light olefin from the effusion from the reaction area. The catalyst consists of a material produced by the moisture evaporation of law material mixture including 100 weight part of molecular sieve having -Si-OH-Al-, 0.01-5.0 weight part of water insoluble metal salt, and 0.05-17.0 weight part of phosphate compound.
