    Abstract: Reactor design and operating conditions enabling adiabatic direct chlorination of metallurgic silicon by hydrogen chloride are presented. The exothermic heat of reaction is absorbed by cooling fluid in admixture with the reactants and products of the reaction, thereby eliminating the necessity of external cooling for the reactor. Reactor temperature is managed by controlling the temperature and composition of reactor feedstock. Feedstock comprises hydrogen, STC, TCS, HCl, and metallurgic silicon. Exemplary feedstock composition, flow-rates, and temperatures are provided. Alternate means of producing the feedstock are described, including a method whereby the feedstock is the product of an upstream STC converter.
