Abstract: Described herein are methods for the continuous preparation of 1,2-di(furan-2-yl)ethane-1,2-diol from furan-2-carbaldehyde. The methods can proceed chemically or electrochemically. In certain examples, the methods further comprise the application of a static mixer. The present methods produce 1,2-di(furan-2-yl)ethane-1,2-diol in greater yield, purity, chemoselectivity, and stereoselectivity than traditional batch methods.

Abstract: Provided herein are one or more heating structures within a reactor for inductive heating, which greatly improve(s) the heating within the reactor. Placing the heating structure results in a more homogenous temperature distribution throughout the reactor interior, which may lead to higher yields, better selectivities, faster adsorbent regeneration, reduced catalyst degradation rates and higher heating rates. The heating structure is formed by connected strands of material which have a diameter of 0.5-100 mm. The heating structure has areas that are susceptible to induction heating. The volume of the total heating structures in the reactor is less than 20 vol. % of the total empty reactor volume. At least a part of the network is formed by strands with a thermal conductivity of 10 W·m−1·K−1 or more at the operating temperature of the reactor.

Abstract: A device for processing waste is described herein that comprises an ion generator, a furnace chamber, a heat exchanger, a pollution control system, and a chimney. The ion generator converts atmospheric air into an ionized gas and the furnace chamber thermally decays the waste by combining the waste with a product of an interaction of the ionized gas and heat generated by the furnace chamber. The heat exchanger cools the excess gas. A wet scrubber system removes heavy metals and/or acid gases from the cooled excess gas to generate scrubbed excess gas, and a fixed bed coke system detoxifies the scrubbed excess gas by converting carbon monoxide, water, and steam in the scrubbed excess gas to carbon dioxide and hydrogen, and removing remaining acid gas, a remaining heavy metal, and/or a remaining dioxin from the scrubbed excess gas. The chimney transfers remaining scrubbed excess gas out of the device.

Abstract: A fixed bed (10) is provided for a fixed-bed reactor (100). The fixed bed (10) contains a particulate carrier and at least one reactive substance. The carrier is a silicate compound and the reactive substance is an organometallic pyridine compound. A method for preparing such a fixed bed is provided. The method includes the steps of preparing the carrier, preparing an impregnation and treating the carrier with the impregnation. In addition, a gas-measuring tube is provided with a correspondingly prepared fixed bed as well. A method uses organometallic pyridinium compounds, especially pyridinium dichromate, in a fixed-bed reactor for detecting alcohol compounds and for preparing formaldehyde and/or acetaldehyde.

Abstract: A cracking reaction device includes a preheating section, a lightening section, a reduced-pressure gasification section and a cracking section that are connected sequentially. A method for producing olefins by cracking involves pressurizing a cracking feedstock and water; subjecting the pressurized cracking feedstock and water to a first heating; subjecting the first heated cracking feedstock and water to a second heating and lightening the cracking feedstock in the presence of water to obtain a lightened mixture; gasifying the lightened mixture under a reduced pressure and subjected to a third heating to obtain a third heated mixture; and cracking the third heated mixture at a cracking temperature in the presence of steam to obtain a cracked product containing olefins.

Abstract: A chemical reactor including reformer tubes for reforming a first feed stream including a hydrocarbon gas and steam. The chemical reactor includes one or more reformer tubes arranged to being heated by an electrically driven heat source. The reformer tube includes a first inlet for feeding said first feed stream into a first reforming reaction zone of the reformer tube, and a feed conduit arranged to allow a second feed stream into a second reforming reaction zone of the reformer tube. The second reforming reaction zone is positioned downstream of the first reforming reaction zone. The feed conduit is configured so that the second feed stream is only in contact with catalyst material in the second reforming reaction zone. A process of producing CO rich synthesis gas at low S/C conditions.
