1. A system for producing enhanced wax alternatives, the system comprising: a reactor comprising a reactor inlet and a reactor outlet; anda high shear device comprising a device inlet, a device outlet, a rotor, a stator, and a catalytic surface, wherein the device outlet is in fluid communication with the reactor inlet. 2. The system of claim 1, wherein the reactor comprises the reactor outlet for gaseous products, and another reactor outlet for liquid or waxy products. 3. The system of claim 1, wherein the rotor and the stator are separated by a shear gap, wherein the shear gap is the minimum distance between the rotor and the stator, and wherein the high shear mixing device operates at a tip speed of the rotor of greater than 4,500 ft/min. 4. The system of claim 1, wherein the high shear device comprises at least one catalytic surface. 5. The system of claim 1, wherein the high shear device is configured to process petroleum wax and base oil with a hydrogen-containing gas to form a feedstock at a shear rate in the range of from about 20,000 s−1 to about 1,600,000 s−1. 6. The system of claim 5, wherein the feedstock comprises gas bubbles with an average bubble size less than about 5 μm, and wherein the reactor is configured for hydrogenation of the feedstock for a time sufficient to produce enhanced hydrogenated products. 7. The system of claim 5, wherein the petroleum wax includes alkane hydrocarbons with formula CnH2n+2, wherein n=20-40. 8. The system of claim 5, wherein the base oil is selected from the group consisting of butterfat, cocoa butter, cocoa butter substitutes, illipe fat, kokum butter, milk fat, mowrah fat, phulwara butter, sal fat, shea fat, bomeo tallow, lard, lanolin, beef tallow, mutton tallow, other animal tallow, canola oil, castor oil, coconut oil, coriander oil, corn oil, cottonseed oil, hazelnut oil, hempseed oil, linseed oil, mango kernel oil, meadowfoam oil, neatsfoot oil, olive oil, palm oil, palm kernel oil, palm olein, palm stearin, palm kernel olein, palm kernel stearin, peanut oil, rapeseed oil, rice bran oil, safflower oil, sasanqua oil, soybean oil, sesame oil, sunflower seed oil, tall oil, tsubaki oil, vegetable oils, marine oils, and combinations thereof. 9. The system of claim 5, wherein the high shear device comprises a second rotor and a second stator, and wherein the shear rate varies along an axis of the high shear device. 10. The system of claim 1, wherein the rotor and the stator are separated by a shear gap, wherein the shear gap is the minimum distance between the rotor and the stator, and wherein shearing conditions comprise a shear rate in the range of from about 20,000 s−1 to about 1,600,000 s−1. 11. The system of claim 1, wherein the high shear device is configured to combine a wax, an oil, and a gas to provide a feedstock comprising gas bubbles with an average bubble diameter of less than about 5 μm. 12. The system of claim 1, further comprising a recycle line configured to transfer a recycle stream from the reactor to the high shear device, and wherein the reactor comprises a nickel catalyst disposed therein. 13. The system of claim 1 wherein at least one of the rotor and the stator comprises a toothed surface, and wherein the reactor comprises a nickel catalyst disposed therein. 14. The system of claim 1, wherein the high shear device comprises a second rotor and a second stator, whereby the shear rate can be varied along an axis of the high shear device. 15. The system of claim 1, wherein the reactor is configured for hydrogenation at a bulk reaction temperature in the range of from about 100° C. to about 260° C., and a bulk reaction pressure in the range of from about 202 kPa to about 6 MPa.
