Enhancing the selectivity for light olefins through catalytic cracking of n-hexane by phosphorus doping on lanthanum-modified ZSM-5.

Naphtha, as the primary raw material in the production of light olefins, could well accommodate their increasing demand through the energy-efficient process of catalytic cracking with ZSM-5. In the current work, different amounts of lanthanum and phosphorous were loaded on ZSM-5 using the wet impregnation method to tune the acidic properties of ZSM-5 for selective catalytic cracking of n-hexane to produce light olefins. Various characterization techniques such as X-ray diffraction (XRD), Al nuclear magnetic resonance (NMR), temperature-programmed desorption of NH (NH-TPD), Py-Fourier transform infra-red (Py-FTIR), inductively coupled plasma optical emission spectroscopy (ICP-OES), N adsorption-desorption, X-ray photoelectron spectra (XPS), and scanning electron microscopy were adopted to investigate the modified zeolites.

Study on the Formation Mechanism of Cold-Rolled Sludge and the Biodiesel Production from Sludge.

Cold-rolled sludge (CRS) has become a challenge due to its large volumetric capacity and high toxicity and is difficult to be degraded under natural conditions. This article aims to explore the feasibility of the solvent extraction method for recovering oil and fat from CRS and utilizing it as a raw material to prepare biodiesel with the application of a homogeneous catalyst HSO to mediate esterification and transesterification. The formation mechanism of CRS was proposed with its detailed analysis; hydroxylates were preferentially adsorbed on the metal surface by hydrogen bonds, and free fatty acids were hooked by carbon chains to form a second layer of adsorption.

Study on the treatment of sulfite wastewater by Desulfovibrio.

In the wet flue gas desulfurization (WFGD) process, SO is adsorbed by alkaline liquor to produce alkaline wastewater containing sulfate and sulfite. Although the traditional chemical treatment method can achieve a high removal rate, it consumes a large number of chemicals and yields a large number of low-value by-products. The biological treatment process is a greener and more environmentally friendly treatment method.

Water-soluble essential oil components of flowers of cultivars and analysis with antidepressant targets.

The present study focused on water-soluble essential oil recovered from the hydrolate of ten cultivars. Thirty-seven components, mostly oxygenated compounds (94.6-99.

A randomized controlled trial of a coping-focused family resilience intervention program for breast cancer patients: Study protocol.

Background: Breast cancer patients and their families are under various pressures in the process of disease diagnosis and treatment, which seriously threaten their physical and mental health. Findings from existing research suggest that good family resilience can help breast cancer families better adapt and cope with adversity and challenges. However, there are only a few intervention studies on family resilience and no intervention studies on resilience among the families of breast cancer patients.

Family resilience, perceived social support, and individual resilience in cancer couples: Analysis using the actor-partner interdependence mediation model.

Purpose: This study aimed to examine the impact of family resilience on the individual resilience of couples during cancer and explore the potential mediating role of perceived social support and the moderating role of sex in this association in cancer patient-spouse dyads.

Method: The participants were 272 cancer patients and their spouses (N = 544) who completed the Family Resilience Assessment Scale, the Perceived Social Support Scale and the Resilience Scale. We adopted the actor-partner interdependence mediation model to examine whether and how patients' and their spouses' family resilience was associated with their own and their partners' perceived social support and individual resilience.
