A program was initiated in July of this year to study the hydrochlorination of silicon tetrachloride and metallurgical grade (m. g.) silicon metal to trichlorosilane, 3 SiCl/sub 4/ + 2 H/sub 2/ + Si reversible 4 SiHCl/sub 3/. A two inch-diameter stainless steel reactor is designed to operate at pressure up to 500 psig and at temperature up to 600/sup 0/C for the hydrochlorination studies. Experiments are planned to collect reaction kinetic data and to conduct corrosion tests for the material of construction for the hydrochlorination reactor. A concept of recycling HCl gas obtained from the hydrolysis of chloride wastes back to the hydrochlorination reactor will be tested. A four inch-diameter hydrochlorination reactor is planned to conduct experiments for the fluidization study. The merits of a fluidized-bed reactor design and a fixed-bed reactor design will be evaluated. The design of the hydrochlorination reactor system has been completed. Construction and installation of the hydrochlorination apparatus are in progress.
