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： The invention concerns particles which may include a catalytically active component, in the form of a three-dimensional ellipsoidal shape having three major axes at least two of which axes are of different lengths. Beds of such particles are useful for forming particle beds through which a fluid may flow.

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： A process includes reacting, in a reactor having a fixed bed containing a solid catalyst which contains a heterogeneous ion exchange resin, hydrogen sulfide and ethylene oxide in the presence of the solid catalyst to yield a reaction product which contains beta-mercaptoethanol. A reactor system includes the reactor, an ethylene oxide stream, a hydrogen sulfide stream, a fixed bed containing the solid catalyst placed in the reactor, and an effluent stream containing the reaction product. During steady state operation of the reactor in the process and the reactor system, the hydrogen sulfide and the ethylene oxide are present in a mole ratio in a range of about 9:1 to about 20:1.

摘要： In a reaction vessel for the purification of crude aromatic carboxylic acid, a bed of hydrogenation catalyst having a vapor space is located above the hydrogenation catalyst bed. A packed bed and a holdup section are located within the vapor space and spaced above the catalyst bed. The reaction vessel has means for introducing crude aromatic carboxylic acid and means for introducing hydrogen to the reaction vessel at respective locations such that in use the crude carboxylic acid contacts the hydrogen in the packed bed. The reaction vessel also has means for removing purified aromatic carboxylic acid.
