RH-KTB and RH-KTB/PB processes are two innovative technologies for producing high quality products from a number of different raw materials. The RH-KTB (Reduction–Hydrogenation–Ketone/TetraBromide) process utilizes a two-stage reaction of reduction and hydrogenation to produce valuable high quality products from feedstock with high moisture content and a low density. The RH-KTB/PB (Reduction–Hydrogenation–Ketone/TetraBromide-Peracetic acid) process utilizes a three-stage reaction consisting of reduction, hydrogenation and peracetic acid to produce high quality products with increased yields and improved product quality.
Both processes represent a major advancement in technology and have been developed to reduce operating costs while increasing production efficiency and capacity. The RH-KTB process offers cost-effective production of high-purity products due to the absence of solvents and consumption of relatively low quantities of materials. In addition, RH-KTB/PB process offers advantages such as yielding better results than the RH-KTB process, improved stability, increased yields and improved product qualities.
The RH-KTB process consists of several steps, beginning with the reduction of the feedstock to the desired level of purity. This is usually accomplished with a reaction of the feedstock with an aqueous solution of hydrazine. The reaction is typically conducted in a pressure reactor at an elevated temperature, usually in the range of 100 to 120°C, and pressure of up to 8 bars. The reaction is generally complete within 10 to 20 minutes.
The second step of the process is hydrogenation, which is performed to convert the contaminants present in the feedstock into soluble products that can be removed easily. This step is typically done in a closed reactor with a catalyst, at temperatures of up to 200°C and pressures of up to 10 bars.
The final step of the RH-KTB process is ketone/tetra bromide, which is used to reduce the high water content of the feedstock as well as to impart greater stability to the product. This reaction is typically done in a pressure-resistant vessel while the feedstock is heated to a temperature of up to 140°C and with a pressure of up to 8 bars.
The RH-KTB/PB process involves three main steps, beginning with the reduction of the feedstock in a similar manner to that of the RH-KTB process described above. The second step is hydrogenation, which is performed in a closed reactor with a catalyst and temperatures of up to 200°C and pressures of up to 10 bars.
The final step of the RH-KTB/PB process is peracetic acid, which is used to further reduce the water content of the feedstock and also to impart greater stability to the product. This step is usually performed in a pressure-resistant vessel while the feedstock is heated to a temperature of up to 140°C and with a pressure of up to 8 bars. The peracetic acid is added to the feedstock and the reaction is completed within 10 to 15 minutes.
Both the RH-KTB and RH-KTB/PB processes offer several advantages over conventional methods for producing high quality products from a number of different raw materials. Examples include: improved product yields and qualities, reduced energy requirements, reduced production costs, and improved stability. Furthermore, both processes can be easily integrated into existing production processes, making them attractive options for many manufacturers.
