  • Systems and methods for producing a supported catalyst
    Patent number: 11618791
    Abstract: A method of producing a supported catalyst includes introducing a dissolved catalyst solution into a catalyst mix vessel, and after introducing the dissolved catalyst solution into the catalyst mix vessel, introducing a porous support material into the catalyst mix vessel. The catalyst mix vessel is then operated to contact the dissolved catalyst solution on the porous support material and thereby generate the supported catalyst, and the supported catalyst is discharged from the catalyst mix vessel.

  • Truck having equipment for on-site heating and collecting used grease from containers
    Patent number: 4450828
    Abstract: A hinged-cover tank truck, for on-site collecting of used deep-frying grease, has a hydraulically powered winch for lifting, swinging and dumping the semi-solid grease from large containers to be emptied and then left at the collection site. A hot-water bath is mounted on the truck so that the container can be immersed therein long enough to melt the periphery of the semi-solid grease mass to facilitating its dumping.
