摘要： A reactor includes a separation membrane, a non-permeation side flow path and a catalyst. The separation membrane is permeable to a product of a conversion reaction in which a raw material gas containing at least hydrogen and carbon oxide is converted to a liquid fuel. The non-permeation side flow path is provided on a non-permeation side of the separation membrane, the raw material gas flowing through the non-permeation side flow path. The catalyst is provided in the non-permeation side flow path and configured to promote the conversion reaction. The catalyst includes catalyst particles each constituted by a carrier and a supported catalytic component, and filler particles softer than the catalyst particles.

摘要： 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.

摘要： In a process for carrying out a chemical reaction gaseous reactants are supplied to a first reaction zone including a first catalyst having a first particle equivalent diameter. The first reaction zone is operated such that when the reactants are contacted with the first catalyst a portion of the reactants is converted to the desired product. An intermediate stream of unreacted reactants and the desired product is removed and passed to a second reaction zone including a tubular reactor. Tubes of the reactor are catalyst carriers containing a second catalyst having a second particle equivalent diameter smaller than the first particle equivalent diameter. The second reaction zone is operated such that when the unreacted reactants are contacted with the second catalyst, at least some of the unreacted reactants are converted to the desired product. A product stream is then recovered. Apparatus for carrying out the process is also described.

摘要： Feedback via an input device associated with an interaction with a point of interest (POI) and scribble recognition is provided. When using an input device to navigate a GUI, various POIs may be determined as elements beneficial for a user to notice, pay attention to, or avoid. When an input is received that may be associated with a POI, feedback may be provided. Feedback may include haptic, visual, or audible feedback. Scribble recognition may also be provided. When using an input device (e.g., digital pen), a user may “scribble” in a margin to test pen attributes. Upon recognizing a scribble, alternative pen attributes may be presented in a contextual menu. In addition, the scribble may be automatically erased upon selection of a pen attribute or upon receiving input in another area of the UI or alternatively, feedback may be provided prior to erasure of the scribble input.

摘要： Disclosed are ruthenium-based catalyst systems, hafnium-based catalyst systems, and yttrium-based catalyst systems for use in ammonia decomposition. Catalyst systems include ruthenium, hafnium, and/or yttrium optionally in combination with one or more additional metals that can be catalytic or catalyst promoters. Hafnium-based and yttrium-based catalyst systems can be free of ruthenium. The catalyst systems also include a support material. Disclosed catalyst systems can decompose ammonia at relatively low temperatures and can provide an efficient and cost-effective route to utilization of ammonia as a carbon-free hydrogen storage and generation material.
