Abstract
In producing low sulfur fuel oil by the ebullated bed hydroconversion of petroleum residue, the resulting heavy vacuum bottoms sulfur-containing residue material is utilized to produce hydrogen. The residue material from the hydroconversion operation is gasified to provide a fuel gas, which is then used to fire a steam-methane reformer. The chemical requirements for hydrogen production are met by feeding a portion of light gaseous products from the hydroconversion step to the catalytic side of the steam-methane reformer. A low sulfur fuel oil distillate product is recovered from the reactor effluent streams and can be further hydrotreated as desired. Thus, all hydrogen required in the H-Oil reactor for hydroconversion and desulfurization is ultimately produced from the residual oil feed material, by using the heavy product residue material to produce a fuel gas and converting the light hydrocarbons to hydrogen.
