Effect of slurry in cat cracking reactor on product yield and quality
- and others
Cracking on microbead zeolitic catalysts is becoming one of the most extensively used processes in petroleum refining. Many paths have been taken in improving the cat cracking process. One of these paths is based on logical application of the principles of physicochemical technology. Feasibility was demonstrated for intensifying the catalytic cracking of vacuum distillate by means of various activating additives, mainly refinery by-products, added to the feed in certain concentrations. By varying the concentration of the additive, the process parameters can be regulated. Of the various parameters, the coke deposition on the catalyst is the most sensitive to the action of additives. We have investigated the possibility of intensifying the cat cracking process by optimizing the quantity of slurry fed to the trapping device of the reactor. It was assumed that the slurry acts in the same manner as additions of products from a different source. In a laboratory unit, we determined the effect of small concentrations of slurry on the material balance in cracking.
