Disclosed herein is a system and method for sulphur-assisted carbon capture and utilization. The system includes a sulphur depolarized electrolyser (SDE) for receiving electricity, H.sub.2O and SO.sub.2 and for electrolysing the H.sub.2O and SO.sub.2 to produce hydrogen and sulphuric acid (H.sub.2SO.sub.4), a decomposition reactor for receiving and decomposing the H.sub.2SO.sub.4 into SO.sub.3 and H.sub.2O, wherein the H.sub.2O is recycled to the SDE, a sulphur submerged combustor for converting the SO.sub.3 to SO.sub.2 and producing S.sub.n vapor, a sulphur power plant for combusting S.sub.n vapor to produce SO.sub.2, electricity and heat and for supplying the SO.sub.2 and the electricity to the SDE and for supplying the heat to the decomposition reactor. The hydrogen is delivered to a carbon capture and utilization facility. An optional Flue Gas Desulphurisation (FGD) regenerable system removes SO.sub.2 from flue gas, a CO.sub.2 converter generates COS, and a separator separates the COS from the flue gas.

This invention relates to a new process to directly produce transportation gasoline from synthesis gas containing principally carbon monoxide, carbon dioxide, and hydrogen, The process entails three sequential catalytic stages with intermediate heat exchange to provide the requisite temperature in each stage, but with no interstage separation. The recycle loop enhances the conversion of the synthesis gas to the desired products and also serves as heat sink for the highly exothermic reactions involved in each stage.

Processes for converting ethane into ethylene include the steps of subjecting a water feed stream to electrolysis to form O.sub.2 and H.sub.2, subjecting a mixture of ethane and O.sub.2 to oxidative dehydrogenation to form a reaction product containing ethylene, acetic acid, water, and CO/CO.sub.2, separating the reaction product into an ethylene product stream, an acetic acid product stream, a water product stream, and a gas stream containing CO/CO.sub.2, and introducing the water product stream into the water feed stream for electrolysis. The ethylene product stream can be contacted with a suitable polymerization or oligomerization catalyst composition to produce ethylene polymers or ethylene oligomers.

The invention relates to a method for improving the transportability of heavy crude oil. Proceeding from the disadvantages of the known prior art a method is to be provided, in which an additive can be used which is producible from a byproduct arising during mineral oil production. The method is to be performable with low expenditure and without any special safety precautions. Further the additive shall lead to an increased yield of conventional petroleum during subsequent refining. According to the invention, an aqueous hydrocarbon mixture having a chain length of predominantly C4 to C12 which does not contain any oxygen-containing hydrocarbon compounds is utilized. This is produced in the area of a mineral oil field from natural gas arising as by-product and/or mineral oil-associated gas. Thereby from the heavy crude oil a crude oil which is light in quality and transportable is obtained. During the subsequent refining of the light crude oil to give conventional petroleum, the amount of petroleum produced is increased by the amount of hydrocarbons present in the aqueous hydrocarbon mixture.
