My research question is high volume of carbon monoxide (CO) and carbon dioxide (CO₂) affect greenhouse effect in the world. How we will eliminate it or we will destroy it. Then CO and CO₂ will destroy atmosphere of earth and affect increasing temperature some research say it is very important.

Researchers who have looked at this subject are Qingjie Ge and Congming Li. They changed CO and CO₂ to LPG, chemical or high value product. They argue that this method used catalyst. It would help decreasing the amount of carbon monoxide, carbon dioxide and decreasing greenhouse effect within the world. 

Qingjie et al. (2008) argued that performance Cu–ZnO/Pd-B catalyst has been investigated under the suitable conditions, catalyst exhibit an excellent catalytic performance for syngas to LPG.

Congming et al. (2014) argued that hybrid catalysts consisting of Zr-Cu–Zn catalyst with Pd-B zeolite were found to show high and stable conversion for CO₂ hydrogenation.

Debate centers on the issue of Qingjie and Congming. The selectivity and conversion of catalyst was changed CO and CO₂ to LPG less than 75%

There is still work to be done on my research will improve catalyst with increasing selectivity and conversion of CO and CO₂ more than 90%

My research will be closest to Qingjie and Congming because I will add the other metal such as Ni, Mo, Ce, Pt, Au and etc into Cu–ZnO/Pd-B catalyst with increasing effective and stability of catalyst to high conversion. The catalyst will used for conversion CO and CO₂ to LPG.

Hopefully, my research will help to improve increasing effective and stability of catalyst and it also help to converse CO and CO₂ to LPG more than 95% when compared with previous catalyst and the product from reaction will get LPG only by the byproduct will not have obtained from reaction.

Stage 1: Carbon dioxide is one of the most abundant and widely distributed carbon resources, and has become the focus of attention because of its greenhouse effects. Therefore, the utilization of carbon dioxide is desirable for the effective method for reducing carbon dioxide emission. Many kinds of strategies with this regard have been proposed to solve this intractable problem (L. Congming et al., 2014). Liquefied Petroleum Gas (LPG), a mixture of propane and butanes, has environmentally benign characteristics and widely been used as clean fuels. Direct synthesis of LPG from syngas is an important choice for converting natural gas to high-value-added products (G. Qingjie et al., 2007).

Stage 2: Many previous studies have reported on the utilization of carbon dioxide for synthesis LPG or chemical. According to Qingjie et al. (2007), they study effect of Cu-ZnO over B-zeolite found that under the suitable conditions, Cu–ZnO/Pd-b catalyst exhibit an excellent catalytic performance for carbon dioxide to LPG: 72.2%. Kenji Asami et al. (2005) reported Co-Mo-Ni in hybrid catalyst could restrain the decomposition of DME into carbon dioxide, but the DME conversion and selectivity for LPG were not high. L. Congming et al. (2014) reported Hybrid catalysts consisting of Zr modified Cu–Zn catalyst with Pd-modified B-zeolite were found to show high and stable conversion for carbon dioxide hydrogenation. The stable activity of carbon dioxide conversion can be attributed to the high water resistant of CZZA. The hybrid catalyst consisting of CZZA with Pd-B was effective for LPG synthesis with selectivity as high as 75%.

Stage 3: From literature review found that the condition of carbon dioxide conversion to LPG was high condition such as high temperature, high pressure etc.

Stage 4&5: In this research work will study catalyst of conversion carbon dioxide to LPG at low condition and study condition of new catalyst. The selectivity of LPG as high as 90%.
