PROCESS FOR RECYCLING HYDROCRACKING HYDROCRACKER RESIDUES IN AN HYDROCRACKER UNVER CONVERTED AFTER REMOVAL OF UNSTABLE POLYNUCLEAR HYDROCARBONS

摘要

P THE FIELD OF THE INVENTION IS THAT OF A HYDROCRACKING PROCESS FOR THE VALORIZATION OF NON-CONVERTED RESIDUES. / P P THE RESOLVED PROBLEM IS TO INCREASE PRODUCTION INTO LIQUID PRODUCTS, MAINTAIN THE ACTIVITY OF CATALYST, AND REDUCE REACTOR ENCRASSMENT. / P P THIS OBJECTIVE IS REACHED BY MEANS OF A CHARACTERIZED PROCESS IN THAT IT CONSISTS OF TREATING THE NON-CONVERTED RESIDUES OF THE HYDROCRACKING UNIT A A SEPARATION STEP FOR REMOVING THE POLYNUCLEAR HYDROCARBONS PRIOR TO THEIR RECYCLING IN THE HYDROCRACKING REACTOR. The invention provides a preferential application for the treatment of particularly heavy crude oils, such as Venezuelan petroleum. / P
