Processes for converting methane and/or other hydrocarbons to synthesis gas (i.e., a gaseous mixture comprising H.sub.2 and CO) are disclosed, in which at least a portion of the hydrocarbon(s) is reacted with CO.sub.2. At least a second portion of the methane may be reacted with H.sub.2O (steam), thereby improving overall thermodynamics of the process, in terms of reducing endothermicity (H) and the required energy input, compared to pure dry reforming in which no H.sub.2O is present. Such dry reforming (reaction with CO.sub.2 only) or CO.sub.2-steam reforming (reaction with both CO.sub.2 and steam) processes are advantageously integrated with Fischer-Tropsch synthesis to yield liquid hydrocarbon fuels. Further integration may involve the use of a downstream finishing stage involving hydroisomerization to remove FT wax. Yet other integration options involve the use of combined CO.sub.2-steam reforming and FT synthesis stages (optionally with finishing) for producing liquid fuels from gas streams generated in a number of possible processes, including the hydropyrolysis of biomass.

According to an embodiment of the present disclosure, petrochemicals may be produced from crude oil by a process which includes passing the crude oil and hydrogen into a hydroprocessing reactor, separating the hydrotreated oil into a lesser boiling point fraction and a greater boiling point fraction, passing the lesser boiling point fraction to a pyrolysis section of a steam cracker to produce a pyrolysis effluent comprising olefins, aromatics, or both, passing the greater boiling point fraction to a gasifier, where the gasifier produces hydrogen, and passing at least a portion of the hydrogen produced by the gasifier to the hydroprocessing reactor.

The present disclosure provides a process that employs glycerol and a catalyst for partial transformation of heavy petroleum oils to lighter hydrocarbon liquids under mild conditions without the need of external hydrogen gas. The process uses industrially produced glycerol to upgrade heavy crudes; hydrogenates aromatics to paraffin and/or olefins without the use of external hydrogen gas; operates at mild operating conditions; and employs inexpensive catalysts. This process is completely different from the hydroconversion process where high pressurized hydrogen gas is essential. The present process requires no pressurized hydrogen gas and can significantly reduce both operating and capital costs of the traditional hydrotreating process.
