A process for preparing Cto Colefins includes introducing a feed stream of hydrogen gas and a carbon-containing gas into a reaction zone of a reactor and converting the feed stream into a product stream including Cto Colefins in the reaction zone in the presence of a hybrid catalyst and in a non-oxidative atmosphere. The hybrid catalyst includes a metal oxide catalyst component comprising gallium oxide and zirconia, and a microporous catalyst component having an 8 membered ring structure. The process also includes periodically introducing an oxidative atmosphere into the reaction zone.

An ergonomic counter-balanced handled tool that is ergonomic and counter-balanced includes a tube that is angled proximate to a midpoint of the tube defining a lower section and an upper section of the tube. The lower section extends transversely from the upper section. A counterweight is slidably coupled to the upper section proximate to a first end of the tube. The counterweight is positionable at a user-selected distance from the first end. A tool is reversibly couplable to a second end of the tube. A harness is couplable to the upper section of the tube, such that the harness is configured to position around a user's shoulder. The counterweight is positioned to extend from the first end of the tube such that the tool and a respective load positioned at the second end are substantially balanced relative to the harness.
