摘要： The present disclosure relates to a method for adjusting grouting parameters in preparation of a ceramic composite fiber-based catalytic filter tube, and a method and a device for preparing a ceramic composite fiber-based catalytic filter tube. In the present disclosure, a loading reference value of a slurry is determined by a fiber length, a pH value, and a solid phase content of the slurry, thus evaluating a performance value of the slurry; initial working parameters for preparation are determined by comparing the loading reference value of the slurry with a preset value. During the actual preparation, a grouting amount is introduced to conduct conversion check on a quality of the slurry, so as to ensure a grouting pressure and a grouting pressure holding time during the grouting.

摘要： A process for the cleaning of a lean gas stream contaminated with volatile organic compounds (VOCs) and/or sulfur-containing compounds comprises the steps of adding ozone to the contaminated lean gas stream, subjecting the ozone-containing lean gas stream to ultraviolet irradiation, thereby transforming VOCs to particles, maintaining the irradiated gas stream in a stay zone for a sufficient time to allow aerosol particle growth, and passing the gas stream through a catalytic bag filter at a temperature down to room temperature to remove the formed particles and eliminate any remaining ozone. The bag filter has been made catalytic by impregnation with one or more metal oxides in which the metals are selected from V, W, Pd and Pt, supported on TiO2.

摘要： A catalyst comprising a Group IIIA metal, a Group VIII noble metal, and an optional promoter metal, on a support selected from silica, alumina, silica-alumina compositions, rare earth modified alumina, and combinations thereof, doped with iron, a Group VIB metal, a Group VB metal, or a combination thereof, offers decreased reactivation time under air soak in comparison with otherwise identical catalysts. Reducing reactivation time may, in turn, reduce costs, both in inventory and capital.

摘要： The present disclosure generally relates to processes for preparation of n-butanol, n-octanol and n-decanol from a reaction mixture comprising ethanoi and n-hexanol by Guerbet condensation. In some aspects, the present disclosure relates to improvements in n-octanol and n-decanol yield and selectivity by the selection of process reaction conditions such as, but not limited to, mole ratio of n-hexanol to ethanol. The present disclosure further generally relates to integrated processes for preparation of n-butanol in a n-butanol reactor from a reaction mixture comprising ethanol and hydrogen to produce a n-butanol product stream by Geurbet condensation comprising n-butanol and n-hexanol and for preparation of n-octanol in a n-octanol reactor from a reaction mixture comprising ethanol, n-hexanol and hydrogen to produce a n-octanol product stream by Geurbet condensation comprising n-butanol, n-hexanol and n-octanol. A predominant proportion of the n-hexanol contained in the n-butanol and n-octanol product streams is isolated and recycled to the n-octanol reaction mixture. In some aspects, the present disclosure relates to improvements in n-octanol and n-butanol yield and selectivity by the selection of process reaction conditions such as, but not limited to, mole ratio of n-hexanol to ethanol and recovery and recycle of n-hexanol.
