Introduction to the Rumus alkylation process
Thread Content
Which friend has experience with Rums alkylation? Could you please introduce it, explain the characteristics of this process and its workflow, and discuss the fundamental differences between it and alkylation using liquid sulfuric acid? If possible, please share some relevant materials.
As one of the components used in high-quality gasoline blends, alkylated oils possess numerous advantages such as a high octane rating, low RVP, low sulfur content, and no aromatic compounds. Alkylated oils are primarily produced through an alkylation process, using C4 olefins and isobutane that are by-products of the catalytic cracking process in refineries as raw materials. China is making vigorous efforts to upgrade clean fuels by reducing the levels of sulfur, olefins, and aromatics in gasoline and diesel. Starting from January 1, 2017, national-wide supply of vehicle gasoline and diesel meeting National V standards will create favorable market opportunities for the alkylation oil industry. Current options for alkylation include liquid acid alkylation processes (using sulfuric acid or hydrofluoric acid as catalysts) and solid acid alkylation processes. The K-SAAT solid acid alkylation process utilizes technology transferred from KBR and proprietary advanced solid acid alkylation catalysts. The KBR solid acid alkylation technology offers the following advantages: 1. It utilizes conventional refining processes, resulting in lower investment costs compared to the sulfuric acid-based process; 2. It yields higher yields than processes using liquid acid catalysts; 3. It is not sensitive to the composition of the feedstock; 4. It has a relatively high tolerance for pollutants; 5. It allows for the modification of existing liquid acid alkylation units. Additionally, KBR’s proprietary advanced solid acid alkylation catalysts are zeolite catalysts that can be used in simple fixed-bed reactors. These catalysts have a much longer alkylation cycle life than other solid acid alkylation catalysts, enabling the production of high-octane alkylated oils without the formation of acid-soluble oils. Moreover, these catalysts can be regenerated using hydrogen.
Hello, are there any existing plants for these two types of alkylation you mentioned? ? Where are they located, and what is the capacity in ten thousand tons? . Thank you
