    Abstract: A multi-stage reforming process is described in which a conventional reforming catalyst (12) is used upstream of an intermediate pore size crystalline silicate containing a Group VIII metal (14). The conventional catalyst is operated at typical reforming conditions and the crystalline silicate is operated at lower pressures. At least a portion of the hydrogen and substantially all of the hydrogen sulfide present is removed (18) from the penultimate stage reformate before it is used in the feed to the final stage.

    Abstract: Poly(oxyalkylene) hydroxyaromatic ethers having formula (I), or a fuel-soluble salt thereof; where n is an integer from 5 to 100; x is an integer from 0 to 10; R1 and R2 are each independently hydrogen, hydroxy, lower alkyl having 1 to 6 carbon atoms, or lower alkoxy having 1 to 6 carbon atoms; R3 and R4 are each independently hydrogen or lower alkyl having 1 to 6 carbon atoms; R5 is an acyl group of formula (a), where y is 1, 2 or 3; R6 is a divalent hydrocarbyl radical, when y is 1, a trivalent hydrocarbyl radical, when y is 2, or tetravalent hydrocarbyl radical, when y is 3, said hydrocarbyl radicals having 1 to about 20 carbon atoms; and each Z is independently selected from the group consisting of (b) and (c) where each R7 is independently alkyl having 1 to 30 carbon atoms, phenyl aralkyl having 7 to 36 carbon atoms or alkaryl having 7 to 36 carbon atoms. The poly(oxyalkylene) hydroxyaromatic ethers of formula (I) are useful as fuel additives for the prevention and control of engine deposits.
