Abstract
Method for preparing acetylene and sodium bicarbonate comprising the operations of: (1) calcining calcium carbonate to produce carbon dioxide and calcium oxide (2) reacting a calcium oxide obtained in this way with carbon, to produce calcium carbide (3) react with water the resulting calcium carbide to produce acetylene and calcium hydroxide and separate the products. (4) reacting the calcium hydroxide thus obtained, with ammonium chloride, to produce ammonia and calcium chloride, (5) reacting the ammonia produced in step (4) and carbon dioxide with sodium chloride to produce ammonium chloride and sodium bicarbonate (6) separating ammonium chloride from sodium bicarbonate and (7) recycling the ammonium chloride thus produced to operation 4.
