Catalytic Steam Reforming

In the preparation of hydrogen, the bio-oil from pyrolysis of biomass must be further upgraded (catalytic steam reforming)SO as to improve its quality．However the catalyst used in the steam reforming reaction is easy to lose its activity due to being coked' SO that it is important to study the coke formation and its efects on the catalyst activity in the steam reforming process．Fourier Transform Infrared Spectroscopy were used to analyze the precursor of coke on the catalyst Ni/MgO-La2O3-Al2O3 used in steam reforming reaction and the mechanism of coking Was also discussed based on it．The results indicate that precursors of coke deposited inside the pore of the molecular sieve are mainly paraffin, alcohols, aldehydes and ketones, and aromatic compounds.

Catalytic Steam Reforming

In this research, catalytic steam reforming acetic acid derived from the aqueous portion of bio-oil for hydrogen production was investigated by using different Ni/ATC (Attapulgite Clay) catalysts prepared by precipitation, impregnation and mechanical blending methods. The fresh and reduced catalysts were characterized by XRD, N2 adsorption-desorption, TEM and H2-TPR. The comprehensive results demonstrated that the interaction between active metallic Ni and ATC carrier was significantly improved in Ni/ATC catalyst prepared by precipitation method, and in which the mean Ni particle size was the smallest (~13 nm) resulted in the highest metal dispersion (7.5%). The catalytic performance of the three catalysts was evaluated through the process of steam reforming of acetic acid in a fixed-bed reactor under atmospheric pressure at two different temperatures, such as 550 ℃ and 650 ℃. Results showed that the Ni/ATC (PM-N/ATC) prepared by precipitation method, achieved the highest H2 yield of ~82% and little lower acetic acid conversion efficiency of ~85% than that (~95%) of Ni/ATC (IM-NATC) prepared by impregnation method. In addition, the deactivation catalysts after reaction for 4 h were analyzed by XRD, TGA-DTG and TEM, which demonstrated that the catalyst deactivation was not caused by the amount of carbon deposition, but owed to the significant agglomeration and sintering of Ni particles in the carrier.

Catalytic Steam Reforming

Catalytic steam reforming of bio-oil is an economically feasible route producing renewable hydrogen. Ni/MgO-La2O3-Al2O3 catalyst was prepared with Ni as active agent, Al2O3 as support and MgO, La2O3 as promoters. The experiments were carried out in a fixed-bed reactor. The content of Ni, calcination temperature, and calcinations time, were investigated with hydrogen yield as index. The optimal preparation conditions were concluded as follows: the Ni content 18%, the calcination temperature 8500C and the calcinations time 6 h.

Artikel ini menjelaskan definisi pirolisis dan pentingnya proses pirolisis dalam konversi termokimia biomassa menjadi bahan bakar. Teknologi pirolisis berpotensi untuk dikembangkan karena ketersediaan sumber bahan biomassa yang sangat melimpah, teknologinya mudah untuk dikembangkan, bersifat ramah lingkungan dan menguntungkan secara ekonomi. Dalam teknik pirolisis, beberapa parameter yang mempengaruhi proses pirolisis adalah perlakuan awal biomassa, kadar air dan ukuran partikel bahan, komposisi senyawa biomassa, suhu, laju pemanasan, laju alir gas, waktu tinggal, jenis pirolisis, jenis reaktor pirolisis dan final produk pirolisis. Reaktor pirolisis adalah alat pengurai senyawa-senyawa organik yang dilakukan dengan proses pemanasan tanpa berhubungan langsung dengan udara luar dengan suhu 300-6000C. Beberapa jenis reaktor pirolisis yang sering digunakan adalah Fixed-Bed Pyrolyzer, Bubbling Fluidized-Bed Reactors, Circulating Fluidized Bed, Ultra–Rapid Pyrolyzer, Rotating Cone, Ablative Pyrolyzer dan Vacuum Pyrolyzer. Teknik pirolisis menghasilkan tiga macam produk akhir, yaitu bio-oil, arang (biochar) dan gas.
