Abstract
Official abstract text for this publication.
A catalyst composition is provided for isomerization of paraffins comprising of at least one heteropoly acid and reduced graphene oxide. Further provided are a process for preparation of the catalyst composition and a process for isomerization of paraffins using the catalytic composition.
First claim
Opening claim text (preview).
What is claimed is: 1. A catalyst composition comprising: at least one heteropoly acid; and reduced graphene oxide, said at least one heteropoly acid selected from the group consisting of tungstophosphoric acid (TPA), molybdophosphoric acid (MPA), and combinations thereof and said at least one heteropoly acid being present in said catalyst composition at an amount of from 15% to 85% by weight based on a total weight of the composition. 2. The catalyst composition as claimed in claim 1 , wherein said at least one heteropoly acid is present in an amount in the range of 15% to 30% by weight based on the total weight of the composition. 3. The catalyst composition as claimed in claim 1 , wherein the reduced graphene oxide is present in an amount in the range of 15% to 85% by weight based on the total weight of the composition. 4. The catalyst composition as claimed in claim 1 , wherein the catalyst is used for isomerization of paraffins. 5. A process for producing a catalyst composition as claimed in claim 1 , the process comprising; contacting at least one heteropoly acid with reduced graphene oxide to obtain a first solution; stirring the first solution for to obtain a second solution; drying the second solution to obtain a dried paste; calcining the dried paste to obtain a catalyst composition. 6. The process as claimed in claim 5 , wherein the first solution is stirred for 8-20 hours at 70-100° C. 7. The process as claimed in claim 5 , wherein the dried paste is calcined at 200-400° C. for a period of 2-6 hours.
