Patent MX-158585-A (MX)
Inventor: HOLMES ARTHUR SHERWOOD
IPC: F25J3/08
Filed: 1981-02-24
Abstract: An improved distillative method of separating an acid gas (e.g. carbon dioxide or hydrogen sulfide) and light hydrocarbons (e.g. ethane, ethylene, or propane) using a distillation column (14) is disclosed in which the formation of an azeotrope between these components is prevented by addition of an additional component to the mixture under distillation.

Title: Producing methanol from methane-containing gas
Inventor: CUMMINGS D
IPC: C10G47/00
Filed: 1980-07-22
Abstract: An economic route to transport fuels from low grade feedstocks containing organic polycyclic components and mineral and/or metallic components comprises separating the feedstock into (a) a residue containing fuel values and substantially all of the mineral and metallic components and (b) a liquid hydrocarbon fraction; hydrogenating the liquid hydrocarbon fraction; providing hydrogen forthe hydrogenation by steam reforming methane-containing gas recovered from the hydrogenated material; and providing the heat for the steam reforming by immersing the reformer reactor tubes in a fluidised bed heated by combustion of residue from the separation step. If the fluidised bed is pressurised, the process can be made substantially self-contained with all the heat and ' power requirements for steam generation and feedstock compression for hydrogenation and steam reforming being recovered from the flue gas.
