Undercarriage system for track-type machine

The undercarriage system of a track-type machine includes a plurality of track roller frame assemblies that are positioned adjacent to a longitudinally extending centerline of the machine. Each roller frame assembly is connected to a plurality of first and second track guiding rollers. The axes of rotation of the guide rollers are offset from the centerline. As a result, the track rollers toe out and in according to the movement of the machine. This design results in a longer wear life for the guide rollers.

The undercarriage system for a track-type machine may be equipped with debris-shunting awning assemblies. These awning assemblies may be retrofitted or factory-installed. A top view of the undercarriage system 22 after installing the awning supports is illustrated in FIG. 6. The right track roller frame 226 is also shown. In order to install the awning assembly 60 on track roller frame 26, follow the steps described in FIG. 6.

Undercarriage components for track-type machines include the main frame, a track roller frame, a drive sprocket, an idler, and a track chain. These components are positioned in a clearance with the main frame. An inboard side of the track roller frame faces the main frame while the outboard side faces the track roller frame.

The undercarriage system for track-type machines also includes track rollers and carrier rollers. These rollers are lubricated throughout their service life. Properly installed rollers enhance durability and extend the life of the machine. An undercarriage system for track-type machines is an important component for a smooth and safe operation.

An undercarriage system for a track-type machine represents up to 50% of its total maintenance and repair cost. As a result, choosing the best undercarriage for your needs will provide the greatest return on your investment. Whether you need a new undercarriage or just need parts, Tractor Supply Company has a complete inventory of undercarriage components for track-type machines. Their knowledgeable staff can help you select the right undercarriage for your machine.

The undercarriage system for track-type machines should also be capable of coping with the rough terrains that these machines are exposed to. This way, they can operate in a variety of environments. For example, they can be used in construction, road building, forestry, mining, and landfills. In these environments, the track-type machine is commonly used to distribute loose materials and dig over them.

Method for mixing two streams of catalyst

The present invention provides a method for mixing two streams of catalyst. In one version of the invention, the catalyst precursor is mixed with a heavy oil feedstock 208 through a metering pump. In another version, the catalyst precursor is mixed with a hydrocarbon diluent 204, which may include decant oil, vacuum gas oil, light gas oil, or start up diesel.

In a second embodiment, the catalyst precursor and feedstock are mixed by passing them along the chamber wall. After mixing, the catalyst precursor and feedstock are passed through a plurality of openings and into the space. This process provides a variety of benefits, including reducing the complexity of the process and operational costs.

In one embodiment, the catalyst precursor is mixed with the heavy oil feedstock, with the catalyst precursor containing a molybdenum salt or complex. This forms a hydroprocessing catalyst. The worldwide demand for refined fossil fuels is growing rapidly, and the supply of high quality crude oil will eventually be exhausted, resulting in an increasing demand for lower quality feedstocks.

Another alternative to the method of mixing two streams of catalyst is to pre-blend one of the streams. In this embodiment, the heavy oil feedstock is combined with the catalyst precursor, with the first stream containing approximately ten to ninety percent of the total flow. However, other mixing configurations may be used, such as one or more static in-line mixers, and one or more high-shear mixers.

The second stream of catalyst and the first stream of regenerated catalyst are mixed by passing through an enlarged lower section of the riser 10. Despite this, the mixture is still not completely mixed, which could lead to non-selective cracking and a composition containing more unwanted products. To prevent this, a ramp may be installed at the connection between the first and second streams.

In another embodiment, the catalyst precursor 102 is mixed with a hydrocarbon diluent 104. Suitable hydrocarbon diluents include cycle oil, light gas oil, and start up diesel. In one preferred embodiment, the catalyst diluent is within the range of fifteen parts per million by weight.

Process for improving catalyst function in auto-thermal and partial oxidation reformer-based processors

The present invention relates to a system and method for improving catalyst function in auto-thermal or partial oxidation reformer-based processor systems. This system allows for increased catalyst life and better separation of different catalysts for better chemical conversions.

The system and method comprises a catalyst support substrate 12, which is made of a heat-resistant material and has a high surface area. This substrate can consist of a single piece or multiple pieces. The substrate has a surface area of one to several m2/g.

The process improves catalyst function by controlling the amount of heat transferred upstream. The upstream catalysts undergo exothermic reactions, which generate high heat. This heat dissipates toward the downstream portion, thereby facilitating the endothermic reaction. During this process, the amount of heat transferred downstream is less than the amount of heat produced in the upstream portion.

Autothermal reforming is a combination of partial oxidation and steam reforming, and is one of the most promising technologies for hydrogen production. It has several advantages over steam reforming, such as easier operation, lower operational temperatures, lower energy requirements, and less coking. However, it requires a significant investment to build a gas-producing plant.

The process improves catalyst function in auto-thermal and partial-oxidation reformer-based processors by using a smaller catalyst volume. The oxidation catalyst’s volume is about one-third of the reformer catalyst’s volume.

The present process improves catalyst performance by using a dual-bed design and features a hexa-aluminate upstream catalyst and an RH catalyst for the downstream finishing catalyst. These features result in greater hydrogen production efficiency. In addition to these advantages, the autothermal reforming process is compact, has a short startup time, and is soot-free.

During the process, the catalysts can simultaneously preheat fuel and provide heat for the reforming reaction. The temperature is affected by the catalyst temperature, oxygen consumption, and reaction rate. When the temperature increases, the kinetics of the reaction are increased. This occurs at a higher temperature than at the inlet.

Various catalyst supports have been studied for their impact on reforming reactivity. While some studies concluded that the support had no effect on catalyst reactivity, others found a strong impact on reforming performance. Moreover, several studies focused on the role of a modifier or a promoter in improving the catalyst’s performance. For example, a catalyst with cerium dioxide as a promoter improves its stability and catalytic activity. It also prevents thermal sintering and carbon deposition.
