VOCs Catalysts – Catalytic Oxidation Catalysts for Volatile Organic Compounds
Full name: Volatile Organic Compounds Oxidation Catalysts. Core principle: At moderate temperature of 200–400 ℃, catalysts activate oxygen to completely oxidize benzene, esters, ketones, alcohols and other VOCs in waste gas into carbon dioxide and water without secondary solid waste. They are core consumables for RCO & RTO regenerative catalytic Read more

Competitive Adsorption Mechanism of Multi‑Component VOCs and Catalyst Design for Synergistic Elimination
VOCs in industrial waste gas mostly exist in the form of mixtures, such as coexisting benzene series, esters and alkanes. Competitive adsorption widely occurs among different components on the catalyst surface. Some refractory components can inhibit the catalytic combustion efficiency of easily oxidized components. Catalyst formulation can rationally designed to Read more

Advantages of Sodium Methallyl Sulfonate (SMAS)-Based Polymers in Mid-to-Late Offshore Oilfield Development
In the middle and late development stage of offshore oilfields, harsh conditions such as high salinity, high temperature, strong ion corrosion, limited platform space and extremely high operating costs restrict the application of conventional polymers. SMAS-based polymers have become the preferred material for offshore development for the following reasons:
Technology
Cost Advantage Mechanism of SMAS-based Polymers in Middle and Late Oil Production
Although the monomer price of Sodium Methallyl Sulfonate (SMAS) is slightly higher than acrylamide, SMAS‑based polymers show outstanding advantages in cost control during middle and late oil production.
Technology
Adaptation Mechanism of Sodium Methallyl Sulfonate (SMAS) Modified Gel for Deep Profile Control in Middle and Late Waterflooding Reservoirs
In the middle and late stage of water flooding, reservoirs are featured with developed high-permeability channels, severe heterogeneity, high temperature and high salinity. Conventional gel systems are prone to dehydration, shrinkage, structural degradation and near-wellbore plugging, failing to reach deep formation. Compared with conventional gels, the gel system prepared with Read more
