    摘要: A heat transfer component that is resistant to both corrosion and fouling is disclosed having a heat exchange surface formed from a silicon containing steel composition including an alloy and a non-metallic film formed on a surface of the alloy. The alloy is formed from the composition η, θ, and ι, in which η is a metal selected from the group consisting of Fe, Ni, Co, and mixtures thereof, θ is Si, and ι is at least one alloying element selected from the group consisting of Cr, Al, Mn, Ti, Zr, Hf, V, Nb, Ta, Mo, W, Sc, La, Y, Ce, Ru, Rh, Ir, Pd, Pt, Cu, Ag, Au, Ga, Ge, As, In, Sn, Sb, Pb, B, C, N, P, 0, S and mixtures thereof. The non-metallic film comprises sulfide, oxide, carbide, nitride, oxysulfide, oxycarbide, oxynitride and mixtures thereof. The surface roughness of the heat transfer component is less than 40 micro inches.

    摘要: The present invention relates to an integrated fluid coking/hydrogen production process. The fluid coking unit is comprised of a fluid coker reactor, a heater, and a gasifier. Solids from the fluidized beds are recycled between the coking zone and the heater and between the heater and the gasifier. A separate stream of hot solids from the gasifier is passed to the scrubbing zone of the reactor. Methane and steam are introduced into the stream of hot solids passing from the gasifier to the scrubbing zone. The hot particles act to catalyze the conversion of methane to carbon monoxide and hydrogen in the presence of steam.
