| Abstract | ||
| The Reduced Crude Residue R.C.R it’s a product of atmosphere distillation from crude oil in the Al-Diwaneyah refinery, where the product from the lower distillation tower at 300 °C thein the atmospheric distillation unit. For Production of Light Petroleum fractions from Reduced Crude Residue R.C.R by Cracking Reaction. Catalytic cracking of reduced crude residue (R.C.R) was joined with a riser pressure continuous reactor was completed in an autoclave with different process selection, temperature about 350–450 °C, catalytic cracking time (60–120) minute, the dosage of catalyst (0.1-0.5) gm and pressure 1–5 bar in the existence of Nitrogen. Statistical program design of testing (RSM) by Box-Behnken (BB) was employed to predict the selection of necessary changes in the cracking by the catalyst of reduced crude residue (R.C.R), and to gain better process conditions. Depended on the (3) plane for the design of the factorial, the cubist system was progressing between the cracking by catalyst conditions to overall production, and the more influential operator for all testing system responses was selected. The prophecy yields and conversion of all upgrade liquid phase, gas phase, coke, and residue were found to agree satisfactory with the testing grade. At a temperature of 400 °C, a pressure of 1 bar, a dosage of 0.3 gm, and a longer residence time (2 h) the best experiment is to get the maximum yield of the liquid phase product. The better run for quality when temperature 400 °C, pressure 5 bar, dosage 0.5 gm and 90 minutes as running time depended on API, sp. gr, density, viscosity, and flash point. | ||
