SILICON POWDER COMPOSITION, METHOD, REACTOR AND DEVICE FOR PRODUCING HYDROGEN

摘要

A silicon powder composition, method, reactor and device for producing hydrogen. Silicon powder composition includes silicon powder, precipitation agent and alkaline substance; wherein alkaline substance is a weak acid salt of alkali metal; mass ratio of alkaline substance to silicon powder is greater than or equal to 0.06:1 and less than or equal to 4:1; silicon powder is a silicon powder with average particle diameter of less than or equal to 1 mm; molar stoichiometric ratio of precipitation agent to silicon in the silicon powder is greater than or equal to 0.12:1 and less than or equal to 4:1. Also presented is a method and reactor for producing hydrogen, and reaction device for producing hydrogen. Silicon powder composition of invention is an optimized formulation which needs no pre-treatment, contains no highly corrosive alkalis, and does not easily burn or explode. Reactor structure and device of invention have relatively high practicability.
