Recovery of Valuable Metals from Waste Petroleum Catalysts by Leaching-Solvent Extraction

We developed a Debaraj Mishra et containing from Ni, V, leaching valuable metals Mo spent catalyst in oil recovery - solvent extraction process. The spent catalyst was washed with acetone and leached with acid. The results showed that the recovery of other valuable metals except Mo was higher. The low recovery of Mo is due to the formation of a layer of impermeable sulfur on the Mo-based. The acid leaching effect is improved by the spent catalyst washed with acetone-carbon disulfide (CS 2 ). Leaching with a 1 mol/L H 2 SO 4 solution followed by washing with (NH 4 ) 2 CO 3 to recover Mo-Ni-V exceeded 90%. The acidic leachate was extracted with a solvent of LIX-841, and Mo and V were separated at different pHs.

1.8Ton electric forklift has DC motor and AC motor. It is widely using in warehouse, no air pollution, low noise, energy saving.

The forklift charger can be designed with different voltage meeting different countries requirement. The Forklift Truck mast has duplex and triplex with height 3 meter, 4 meter, 4.5 meter, 5 meter, 5.5 meter and 6 meter. Forklift tire has air and solid two models. 1.5 t mini electric forklifts can be installed with different attachments: side shifter, positioned, bale clamp, paper roll clamp, and others

The machine has following advantages:

Low noise: Noise <82AB (A)

Easy maintenance: battery cover is with gas-filled cylinder, the open range can be 78-90 degree

Safety: the cylinder is with dual safety system:. Lowing safety valve &lowing limited valve

           LCD digital display can fast monitor truck status

           The electric F/R lever with neutral safety start system
