Abstract
The present disclosure provides a catalyst represented by Formula (I) X[(ROa)(QOb)]*Z (I), wherein the moiety X[(ROa)(QOb)] and the moiety Z are mechanically mixed; wherein the weight percentage of the moiety Z is about 1% to about 99% of the total weight of the catalyst. Furthermore, the present disclosure provides a tunable, low-temperature, energy-efficient process for hydrocracking plastics to form a fuel, a lubricant, or a mixture thereof.
Claims19
A process for hydrocracking plastics, comprising contacting the plastics with a catalyst in a hydrogen atmosphere at a temperature between about 150° C. and about 800° C. for a period of time between about 0.1 hours and about 120 hours to form a fuel, a lubricant, or a mixture thereof;
- wherein
- the catalyst is represented by formula:
- X[(ROa)(QOb)]*Z (I), and
- wherein
- X is a noble metal selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium, and platinum;
- R and Q independently are a transition metal;
- O is oxygen;
- a and b independently are 1, 2, 3, or 4;
- Z is a zeolite or a mesoporous material;
- and
- the symbol “*” means that the moiety X[(ROa)(QOb)] and the moiety Z are mechanically mixed;
- wherein the weight percentage of the moiety Z is about 1% to about 99% of the total weight of the catalyst.
