Abstract: A process can produce alcohols having at least two carbon atoms by catalytic conversion of synthesis gas into a mixture containing alkanes, alkenes, and alcohols. Alkenes are converted into corresponding alcohols in a subsequent step by hydration of the alkanes. Before the hydration and after the catalytic conversion, gas and liquid phases may be separated. Specific catalysts can be employed that have a markedly higher selectivity for alkenes than for alkanes. These catalysts comprise grains of non-graphitic carbon having cobalt nanoparticles dispersed therein. The cobalt nanoparticles have an average diameter dp from 1 to 20 nm, and an average distance D between nanoparticles is from 2 to 150 nm. The combined total mass fraction of metal ω in the grains ranges from 30% to 70% by weight of the total mass of the grains of non-graphitic carbon, wherein 4.5 dp/ω>D≥0.25 dp/ω.

Abstract: Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.

Abstract: A method to selectively remove metal compounds and sulfur from a petroleum feedstock is provided. The method comprising the steps of feeding a pre-heated water stream and a pre-heated petroleum feedstock to a mixing zone, mixing the pre-heated water stream and the pre-heated petroleum feedstock to form a mixed stream, introducing the mixed stream to a first supercritical water reactor to produce an upgraded stream, combining the upgraded stream and a make-up water stream in a make-up mixing zone to produce a diluted stream, wherein the make-up water stream increases the ratio of water to oil in the diluted stream as compared to the upgraded stream, and introducing the diluted stream to a second supercritical water reactor to produce a product effluent stream. The method can include mixing a carbon with the make-up water stream.
