Abstract
A process is disclosed for reducing the level of compounds of certain metals from hydrocarbon liquids by contacting said metal compound-bearing hydrocarbon with acidified active carbon. The process is particularly useful for preferentially removing organo lead compounds from gasolines at mild conditions, with only small removal of organo manganese antiknock compounds such as methyl cyclopentadienyl manganese tricarbonyl which may be present.
Claims9
A process for the reducing of levels of compounds of metals of Groups Ib, IVa, Vb, VIB and VIII in light hydrocarbon liquids which comprises contacting said liquids with a sorbent consisting essentially of particulate active carbon having at least a majority of its pore volume in pores having a diameter greater than 0.9 nm, which sorbent has previously been oxidized by contact with a highly acidic oxidizing fluid and substantially separated from said oxidizing fluid.
A process for selectively reducing the level of organoalkyl lead compounds present in gasoline with comparatively small reduction of organo manganese compounds present in the gasoline which process comprises contacting the gasoline with a sorbent consisting essentially of particulate active carbon having at least a majority of its pore volume in pores having a diameter in the range from 1 to 10 nm which sorbent has previously been oxidized by contact with a highly acidic oxidizing fluid.
A process for preferentially removing organo lead compounds from hydrocarbon liquids with only small removal of organo manganese compounds which comprises contacting said liquids with a sorbent consisting essentially of particulate active carbon having at least a majority of its pore volume in pores having a diameter greater than 0.9 nm, which sorbent has previously been oxidized by contact with a highly acidic oxidizing fluid and substantially separated from said oxidizing fluid.
