When total sulfur content of the feedstock is 0.85% and NS FCC desulfuration agent occupies 4%～5% of the catalyst in the system, dry point of the FCC gasoline reduces from 186℃ to 177℃, and the total sulfur content in the gasoline has been decreased by 39% without negative influence on the catalyst and product slate.
The experiment results showed that under the conditions of a reaction temperature range of 400-500℃, a space velocity range of 0.5-1.0h~ -1 and low reaction pressure, the product slate and product properties as well as the operating cycle were met the requirement.
The ICR regenerated catalyst had been used in the hydrocracking unit of Shengli Refinery 8 months. The operating results showed that the catalyst kept good activity, and both of the product slate and quality met the requirements.
The results show that production distribution is good,the solidification point of diesel fuel reaches-29 ℃,and the solidification point of lubricating oil reaches-16 ℃ when reaction temperature is 400 ℃,reaction space velocity is 2 h~(-1) at normal pressure and without hydrogen.
The catalytic performance,production distribution and property were studied under the temperature of 340～380℃ and space velocity of 1～4 h-1.The experimental results showed that the production had good distribution and desired property.
The emulsified heavy oil and heavy oil are tested in FCC reaction at the same operating conditions to investigate their respective product slates, coke make, product quality and cracking catalyst performance.
The commercial trial of the Agent A on small fixed-bed FCC unit demonstrate that the addition of this agent has signifi-candy improved the product slates of CGO feed or mixed feed and increased light product yield and total conversion.
