Abstract
ในกรรมวิธีสำหรับรีดิวส์วัสดุที่มีเหล็กออกไซด์โดยตรง ผสมแก๊สสังเคราะห์กับแก๊สส่วนบนที่เกิดขึ้นจากการรีดิวส์วัสดุ ที่มีเหล็กออกไซด์โดยตรง และใช้เป็นรีดิวซิงแก๊สสำหรับการ รีดิวส์โดยตรงและสำหรับทำให้วัสดุที่มีเหล็กออกไซด์ร้อนถึง อุณหภูมิรีดิวส์ ในการปรับปริมาณของ H2S ให้ได้ค่าตามที่หาไว้ก่อนแล้วโดย หลีกเลี่ยงกรรมวิธีและโครงสร้างที่มีค่าใช้จ่ายสูง ป้อน กำมะถันที่มีอยู่ในวัสดุที่มีเหล็กออกไซด์อย่างน้อยส่วน หนึ่งร่วมกับแก๊สส่วนบนไปในรีดิวซิงแก๊สในรูปของ H2S ที่ เกิดจากการให้ความร้อนและในการรีดิวส์โดยตรงตามลำดับ In processes for direct redox material containing iron oxide. Mix synthetic gas with the upper gas formed by the reduction of material. With iron oxide directly And is used as a reducing gas for Direct redundant and for heating iron oxide-containing materials to Reduce temperature To adjust the amount of H2S to get the previously determined value by Avoid costly processes and structures to feed the sulfur contained in at least partially iron oxide-rich materials. One, in combination with the upper gas, goes into the reduction of the gas in the form of H2S generated by heating and in the direct reduction respectively.
