Catalytic Dealkylation Technology for Producing Benzene

Catalytic Dealkylation Technology utilizes toluene as a feedstock to produce benzene through a catalytic hydrodealkylation process. By optimizing the match between the hydrogenation active sites and acidic sites of the catalyst, this technology enhances side-chain cleavage activity while suppressing aromatic ring hydrogenation activity, thereby significantly improving benzene selectivity under relatively mild reaction conditions. This technology helps optimize the product structure of refineries, contributing to improved product quality and operational efficiency.

Key Features & Benefits

Superior catalyst performance

High catalyst activity, excellent stability, and high benzene yield and selectivity.

Simplified process flow

Single-stage fixed-bed process.

Mild operating conditions

Low reaction temperature, reduced energy consumption, and lower material requirements for reactors.

Technical Parameters

With the increasing trend of crude oil becoming heavier and of lower quality, there is an urgent demand for the chemical utilization of heavy aromatic resources. Meanwhile, under the new circumstances of refinery transformation, cost reduction and efficiency improvement, green and low-carbon development, and diversification of feedstock sources have become inevitable trends.

Additionally, the future aromatics market, particularly for para-xylene (PX), faces the risk of oversupply, prompting a shift of the aromatics industry toward high-end fine chemicals. The platform technology for aromatics enhancement and high-value utilization aligns with industry development trends, offering new ideas for enterprises to achieve green and efficient growth, with broad application prospects.
