Spray nozzle for catalytic cracking experiment and application

Abstract

The invention relates to a spray nozzle for a catalytic cracking experiment and an application. The spray nozzle can simultaneously spray three raw materials and comprises a hydrocarbon oil I outer sleeve pipe, a hydrocarbon oil I inner sleeve pipe, a hydrocarbon oil I outer spray head, a hydrocarbon oil I inner spray head, a hydrocarbon oil II sleeve pipe, a hydrocarbon oil III sleeve pipe, a steam chamber, a hydrocarbon oil I and steam mixing chamber, a hydrocarbon oil II spray head, a hydrocarbon oil III spray head, a hydrocarbon oil II circular atomizing chamber and a hydrocarbon oil III circular atomizing chamber. According to the invention ,through arrangement of the hydrocarbon oil II circular atomizing chamber and the hydrocarbon oil III circular atomizing chamber on the spray nozzle, the spray nozzle provided by the invention can simultaneously spray three raw materials, and can be used for an experimental for experimental study of simultaneous contact and reaction of different catalytic raw materials with a catalyst; and light hydrocarbons sprayed by the hydrocarbon oil II spray head and the hydrocarbon oil III spray head preferentially contact with the catalyst for a reaction to generate a large amount of carbonium ions, so conversion of heavy hydrocarbons is accelerated, and the spray nozzle provided by the invention has the characteristics of increasing the yield of liquefied gas, gasoline and low-carbon olefins and improving total liquid yield and conversion rate.

AI Technical Summary

Benefits of technology

This new type of nozzled apparatus used during catalysis tests helps improve efficiency by allowing multiple types of material to react together quickly without forming channels or causing damage from other things that may come into play within it's own design. It allows for better control over the amount of each ingredient being injected while still providing effective results through various techniques such as mistracking.

Problems solved by technology

This patented technical solution describes a method called catalysis cracker testing (CAT) where different starting materials like petroleum hydrogen sulfur compounds or alcoholic liquids were mixed together before being applied onto a specific type of catalyst during experiments. By adjusting the amount of each ingredient added based upon factors including temperature differences across multiple stages within the apparatus, the resulting mixture could contain varying amounts of these substances depending on whether they should be separated separately when analyzing their effects on the final outcome of the experiment.
