It has the following salient features:<\/p>\n<p>1. Reasonable heat utilization, optimized heat exchange method, and improved thermal efficiency.<\/p>\n<p>2. Select the anti-carbon evolution conversion catalyst, and the upper and lower catalysts have different sizes to ensure the conversion rate while fully considering the resistance of the furnace tube.<\/p>\n<p>3.
