NettetNaphtha reforming. The most widespread process for rearranging hydrocarbon molecules is naphtha reforming. The initial process, thermal reforming, was developed in the late 1920s. Thermal reforming employed temperatures of 510–565 °C (950–1,050 °F) at moderate pressures—about 40 bars (4 MPa), or 600 psi—to obtain gasolines (petrols ... NettetSteam cracking heavy 
feedstocks of naphtha and gas oils produces about 60% of the global propylene demand, while 30% comes from traditional FCC units that produce …

The initial process, thermal reforming, was developed in the late … NettetDifferent regions favor different feedstocks. For example, some ammonia producers use naphtha, petroleum coke, or even heavy fuel oil as their hydrogen source. Ammonia is the second-most synthesized chemical on the planet (behind sulfuric acid), with a global production in 2024 of around 170 million metric tons (m.t.) (2). strausbaugh law

Bionaphtha: The Renewable Alternative to Fossil-Based Naphtha

NettetThe products produced in the reaction depend on the composition of the feed, the hydrocarbon-to-steam ratio, and on the cracking temperature and furnace residence time. Light hydrocarbon feeds such as ethane , LPGs or light naphtha give product streams rich in the lighter alkenes, including ethylene, propylene, and butadiene . NettetNaphtha is an attractive feedstock for propylene production. Existing processes can convert naphtha into 15-20% propylene. Steam crackers cracking naphtha at high … NettetNatural gas liquids and naphtha that is created from crude oil during the refining process are used as feedstocks to manufacture a wide variety of petrochemicals. … strausbaugh polisher
