The catalytic co-pyrolysis of a seaweed biomass, Laminaria japonica, and a typical polymer material, polypropylene, was studied for the first time. A mesoporous material Al-SBA-15 was used as a catalyst. Pyrolysis experiments were conducted using a fixed-bed reactor and pyrolysis gas chromatography/mass spectrometry (Py-GC/MS). BET surface area, N2 adsorption-desorption isotherms, and NH3 tempe...

Steam reforming is one of the most important processes for producing hydrogen from hydrocarbon fuels such as LPG and has attracted much attention due to its high efficiency and economy. In this study, the LPG steam reforming reaction was investigated on nickel catalysts supported on four various zeolites (H-Y, Na-Y, HZSM5 and Ferrierite). The catalytic tests were performed in a tubular fixed be...

The techno-economic performance and CO2 equivalent (CO2eq) reduction potential of bio-based aromatic production cases with without capture storage (CCS) have been evaluated compared to those fossil-based production. bio-cases include tail gas reactive pyrolysis (TGRP), catalytic (CP), hydrothermal liquefaction (HTL), gasification-methanol-aromatics (GMA), Diels-Alder furan/furfural combined lig...

CO2 reforming of methane (CRM) over unpromoted and potassium promoted Ni/Al2O3 catalysts was studied. The catalysts were prepared by impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption (BET), temperature programmed reduction (TPR), temperature programmed oxidation (TPO) and scanning electron microscope (SEM) techniques. The obtained results showed that addition of K2...

Among the current IPPC installations, steam cracking for olefin production is the single most energy consuming process (ca. 30%) in the chemical industry, accounting for ca. 180 million tons of CO2 worldwide. This paper reviews steam cracking and innovative emerging olefin technologies in terms of energy efficiency. Pyrolysis section alone consumes ca. 65% of the total energy use and ca. 75% of...

whereas American industry has available large supplies of natural gas; the refiner in the U.S.A. can therefore produce high quality fuels partly by catalytic cracking of heavy distillates, but his European counterpart has no such opportunity and must rely to a much greater extent on catalytic reforming processes to produce high quality fuels from straightrun naphthas. Again, while demand for hi...

The naphtha reforming process converts low-octane gasoline blending components to high-octane components for use in high-performance gasoline fuels. The reformer also has an important function as the producer of hydrogen to the refinery hydrotreaters. A process model based on a unit model structure, is used for estimation of the process condition using data reconciliation. Measurements are clas...

Complex process networks featuring multiple energy integration agents (processto-process heat exchangers) offer significant cost benefits while adding additional operational constraints. These networks show potential for multi-time scale dynamics owing to the presence of energy flows spanning multiple orders of magnitude. In previous work, we have developed a graph-theoretic framework to system...
