What are the effects of high calcium and sulfur contents in hydrogenation feedstocks on hydrogenation? What aspects should be paid attention to in production? How to solve it?
A high calcium content can lead to an increase in pressure drop across the device, resulting in deviation from the optimal operating conditions; this issue cannot be resolved by using catalysts. Due to the high sulfur content, catalysts with high activity that offer good desulfurization performance must be selected; otherwise, the operating temperature will have to be increased, which reduces the catalyst’s service life.
A high sulfur content has an impact on the temperature rise during the reaction. Most importantly, an increased H2S level requires thorough desulfurization; otherwise, it will cause severe corrosion to the equipment
