  • Publication number: 20220146041
    Abstract: A wearable holder for securely holding an electronic device, for example, a laptop is disclosed. The wearable holder is configured to enable the user for securely holding the electronic device on a person's body in a hand-free manner, thereby effectively utilizing the electronic device while avoiding droppings. The wearable holder comprises two straps having a respective first and second ends, at least two corner support holders, and a buckle clip. The corner support holders are securely sewn underside of both straps at spaced locations, wherein the two corner support holders are adapted to support the corners of the electronic device. The buckle clip is disposed at respective first ends of both straps for adjusting the straps.

  • Patent number: 9840447
    Abstract: The invention relates to a method for extracting hydrocarbon mixtures that have an increased proportion of hydrocarbons of a medium chain length (8 to 16 carbon atoms), or the corresponding pure compounds. Firstly, a starting material is provided that includes at least 50 wt. % unsaturated hydrocarbon compounds having oxygen. The compounds include olefin fragments of the formula —C1CxH2x—CH?CH—CyH2y+1 with at least 14 carbon atoms, carbon atom (C1) being saturated with substituted or unsubstituted heteroatoms and/or hydrogen. In a conversion reactor, this starting material is brought into contact with a porous catalyst based on carbon, in the absence of oxygen, and at a temperature of between 200 and 800° C.; and a product mixture that contains hydrocarbons is produced containing an increased proportion of hydrocarbons with medium chain lengths. Finally, the product mixture including hydrocarbons is collected and fed to a separating device in which a product separation is carried out.

  • Patent number: 8686210
    Abstract: A process for obtaining gaseous hydrocarbons from a starting material which contains oxygen-containing hydrocarbons. The process includes providing the starting material and contacting the starting material with a porous catalyst at a temperature of 300-850° C. in the absence of oxygen in a converting reactor so as to form a hydrocarbon-containing product gas mixture in which a proportion by weight of gaseous hydrocarbons is greater than a proportion by weight of liquid hydrocarbons in the gas mixture. Additionally, the process includes collecting a hydrocarbon-containing product gas stream of the hydrocarbon-containing product gas mixture and introducing the product gas stream into a separation apparatus in which product fractionation is carried out.

  • Publication number: 20110237854
    Abstract: The invention relates to a method for extracting gaseous hydrocarbons, in particular liquid gas and/or a gas mixture resembling natural gas or one or more components contained in liquid gas or in the gas mixture resembling natural gas. The starting material used contains oxygen-containing hydrocarbons. The method comprises the following steps: providing the starting material—contacting the starting material with a porous catalyst in the absence of oxygen at a temperature of 300-850° C. in a converting reactor, resulting in a hydrocarbon-containing product gas mixture, in which the proportion by weight of the gaseous hydrocarbons is greater than that of the liquid hydrocarbons, —collecting the hydrocarbon-containing product gas stream and supplying the product gas stream to a separating device, where product separation is performed.
