1. 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[(RO_a)(QO_b)]*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[(RO_a)(QO_b)] 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.
