    Abstract: Process and reaction system for the preparation of methanol. The process comprises the steps of (a) providing a fresh methanol synthesis gas containing hydrogen, carbon monoxide and carbon dioxide; (b)) introducing and reacting the fresh methanol synthesis gas stream in a first methanol reaction unit in presence of a methanol catalyst and obtaining a first effluent stream containing methanol and unconverted synthesis gas; (c) providing a recycle gas stream containing the unconverted methanol synthesis gas contained in the first effluent stream and unconverted methanol synthesis gas from a second methanol reaction unit; (d) introducing and reacting the recycle gas stream in the second methanol reaction unit in presence of a methanol catalyst; (e) withdrawing a second effluent stream containing methanol and the unconverted methanol synthesis gas from the second methanol reaction unit; (f)) combining the first and a part of the second effluent stream; (g) cooling and separating the combined effluent into a methanol-containing liquid stream and the recycle stream; and (h) withdrawing the remaining part of the second effluent stream a purge gas stream,wherein the remaining part of he second effluent stream is withdrawn as a purge gas stream prior to combining the first and second effluent stream.

    Abstract: A lithium positive electrode active material intermediate comprising less than 80 wt % spinel phase and a net chemical composition of LixNiyMn2-yO4-δ wherein 0.9≤x≤1.1; 0.4≤y≤0.5; and 0.1≤δ; where the lithium positive electrode active material intermediate has been heat treated in a reducing atmosphere at a temperature of from 300° C. to 1200° C. A process for the preparation of a lithium positive electrode active material with high tap density for a high voltage secondary battery where the cathode is fully or partially operated above 4.4 V vs. Li/Li+, comprising the steps of a) heating a precursor in a reducing atmosphere at a temperature of from 300° C. to 1200° C. to obtain a lithium positive electrode active material intermediate; b) heating the product of step a. in a non-reducing atmosphere at a temperature of from 300° C. to 1200° C.
