Claim Text:
1. A process for preparing a phosphorus containing mesoporous Al 2 O 3 catalyst, wherein said process comprising the steps of: a) preparing a first solution by i) mixing aluminum isopropoxide in ethanol to give a mixture; ii) adding phosphoric acid, nitric acid and ethanol into the mixture to form a solution; and iii) stirring the solution for a period of 9-11 hrs at 25° C. to 35° C.; b) preparing a second solution by mixing Poly(ethylene glycol)-block-poly(propylene glycol)-block-poly (ethylene glycol) in ethanol; c) mixing two solutions consisting of the first solution and the second solution as obtained in steps (a) and (b) and stirring for a period of 3-5 hrs at 25° C. to 35° C. to give a third solution; d) obtaining a crude phosphorus containing mesoporous Al e) calcining the crude phosphorus containing mesoporous Al
