Alkylation is a process used to produce highly branched isoparaffins from the reaction of lighter olefins and isobutane in the presence of sulfuric acid as a catalyst. This highly branched isoparaffins is called alkylate – a blending component that constitutes approximately 10% – 15% of the gasoline pool in the U.S. Besides the ability to increase octane and lower Reid vapor pressure (RVP) in the gasoline pool, alkylate also reduce vehicles exhaust emissions with zero olefins, zero aromatics and low sulfur.

Catalyst is at the heart of all sulphuric acid plants and plays a critical role
in plant performance. This article provides an overview of the specific design
features of two new types of MECS® sulphuric acid catalyst developed by DuPont Clean Technologies (DuPont), XLP-310 and SuperGEAR™, and explains how these more advanced catalyst types can be applied to reduce emissions or increase the capacity of a sulphuric acid plant.

Across the globe, governments and communities are focused on reducing pollutants that have adverse environmental and health effects. Particulate, sulfur dioxide and nitrogen oxides are of specific concern. Carbon black production has been recognized as an industry that needs to address stack emissions by many countries, communities and operators. By the nature of the feedstocks used, which are derivatives of coal, natural gas and oil, sulfur dioxide (SO2) is present in the off gas. The formation of nitrogen oxides (NOx) is also expected in the reactor
based on process temperatures. To curb emissions of SOx and NOx, many carbon black producers have incorporated low sulfur fuels, low NOx burners and heat recovery into their process. However, there is a direct relationship between carbon black production plant size and exhaust gas volume. Thus, with recent industry consolidation and construction of larger plants, exhaust gas volumes have increased. With environmental regulations continually tightening, producers may need to consider new, more robust exhaust gas emissions control options to further drive down emissions.
